    Review & Install Video

    The BBK High Flow Aluminum Fuel Rail Kit is available for the '99 to '04 Mustang GT owners who are looking to push the horsepower limit of their 4.6-Liter motor and need a more capable fuel rail system in order to handle the proper amount of fuel needed for their setup. This particular kit is finished in blue and includes everything you need at a more affordable price than most options on the site. The installation for fuel rails and lines aren't exactly a walk in the park, as they do require you to remove the manifold and have a little mechanical knowledge, so I'm giving this one full three out of three wrenches on our difficulty meter, which I'll talk more about later on. First and foremost, why would you need to upgrade your fuel lines and rails to a high-flow kit like this? Well, plain and simple, you might need more fuel delivered to your cylinders to keep up with the power you wanna put to the tires. Fuel rails and lines are a part of that system. There are three main components to the delivery system, which consist of fuel pump, fuel lines and rails like here, and the fuel injectors. The stock setup can only handle so much, so when you're pushing your motor to and past the limit, you need to start replacing those parts with aftermarket ones that you know can get the job done. Now, the reason I said you might need more fuel delivered is because it really depends on your particular setup. The factory fuel rails can tend to limit the amount of fuel being delivered because it can only handle so much. You're pushing more power than it can handle, which is typically right around the 500 wheel horsepower mark. They can tend to act as a bottleneck and even bend, in some cases, and break. The stock pump and injectors are known to handle more than the rails, so this might be the first stop in upgrading the fuel delivery system.With the high-flow system I've got here, you're able to open up the passageway when your motor is chugging the fuel going in in order to output its maximum potential. Since these are CNC-machined out of a lightweight billet aluminum, they're able to handle maximization far better than the stock wimpy rails ever could. The blue anodized finish helps with longevity, but it also looks pretty good peeking out under the manifold as well, which is always a plus.BBK typically makes some pretty budget-friendly parts, and this one is absolutely no different. For just above the $200 mark, this kit comes with the two rails you see here as well as the proper hose fitments and all the hardware needed for the installation. It's not a bad idea to pick up a set of braided stainless steel fuel lines as well to help complete the flow to your cylinders with some more reliable parts. Keep in mind this is going to need a tune since you're altering the amount of fuel being delivered, and you can work with your tuner to determine whether or not you wanna pick up some upgraded injectors and/or a new fuel pump to help with the delivery system completion. It really all depends on your particular setup. I know I've said that a bunch of times, but it's very important. The amount of fuel pressure, the boost levels, and if you're going with forced induction is all up between you and your tuner. There's a lot of variables that can come into play, so you wanna take that into account. The installation is definitely gonna require some mechanical expertise, as I mentioned in the beginning. As far as tools, you'll need a spring lock type fuel line disconnecting tool, which, if you don't have, you can get at your local auto parts store. Most of them will rent it out for you, so you don't have to worry about buying it for a one-time use. Also, having an 11/16ths-inch wrench, a 12-millimeter, 10-millimeter, and 8-millimeter socket and a ratchet, 5-millimeter and 5/32nds Allen wrench, white lithium grease, Teflon tape, and anti-seize locking grease as well. Obviously, very specific tools here, so you wanna make sure you have the right ones on deck before you get started. If you don't have the expertise or a helping hand to get this one installed, there's no shame handing it over to a professional to get done properly. Definitely give this one full three out of three wrenches on our difficulty meter. It'll take a couple of hours from start to finish. There have been some reports and controversy over the fitment issues with different sets of coil-on plugs and different aftermarket manifolds. The truth is this is made to work with most aftermarket manifolds and almost all plugs, include MSD. You'll definitely wanna make sure you're using the correct tools I mentioned a second ago, but other than that, there is some good, old-fashioned elbow grease involved to do the trick. There are instructions provided in the kit to help you along your way, of course, and our customer service team is always willing to give you a hand.That just about wraps this one up. So if you're the owner of a '99 to '04 GT Mustang, you might wanna check out the BBK High Flow Aluminum Fuel Rail Kit, available right here at americamuscle.com.

    Better Fuel Flow. BBK High Flow Aluminum Fuel Rails replace those skinny stock fuel rails to reliably flow more fuel to your high performance engine.

    More Power. Whether your fuel system is bone stock or already has several upgrades these BBK Aluminum Fuel Rails will make a noticeable improvement in fuel flow for more power. It is well known that the stock injectors will handle a significant amount more power than your thin and often bent factory fuel rails can provide, so upgrade to BBK's High Flow rail kit for maximum flow.

    Quality Construction. Crafted from lightweight aluminum each fuel rail is CNC machined to precise tolerances for maximum performance and completed in a blue anodized finish for longevity.

    Application. The BBK High Flow Aluminum Fuel Rails are specifically designed for use on the 1999 to 2004 4.6L 2V GT Mustangs with either stock or aftermarket intake manifolds.

      Quality

      First things first, I am going to put some other reviews' rumors to rest. If you have MSD COP's...these fuel rails fit just fine. About the crossover hose popping off - you have to use some serious man-hands to put them on the elbow fittings in the first place. Then, if you're still unsure, get some hose clamps. Bottom line is, these are made well, and are a great upgrade. I liked how solid they were compared to the stock rails, both beefy and secure when mounted to the intake manifold. The provided instructions SUCK, lack of quality pictures, and no installation video on their website (even though it said there was?). Anyway - install went decent - just remember that that driver side rail and the passenger side rail are actually flipped to oppose each other - meaning if you assembled both rails to 'look' the same side by side - one of them is backwards. One last piece of advice - have an A/C and Fuel Line Disconnect Tool (supplied directions call them Snap Lok Pliers - and no one knows what those things are). Can get them at most auto parts stores. They are a weird looking little tool that are a -must have- to remove the spring-locking quick disconnect fitting on the factory fuel rail. After anguishing over that for more time than I needed to, we got them, used them, and bam, the install was done. They fit great, work great, look great, and are the final word when it comes to fuel rails for the pony. Great buy!

      bbk rails for bullitt

      first off let me say, they look great and provide a decent power increase, about 15 horsepower; but if you have a bullitt you need to know what your getting into. there is a bracket on the driver side near the rear of the stock fuel rail that will have to be modified in order to get the bbk rails to fit do to the fact that they are longer. (i used a small cut off wheel on an air tool) you must widen the hole thru the center of the bracket about an inch on the left side(it is also very difficult to get the bracket off). on the passenger side, the intake manifold stretches out over the stock rails, and because bbk's are also taller it can be difficult to get them in. the easiest way is to insert the fuel rails (with the injectors in them) at a 45 degree angle under the jutting intake manifold and twist them up and the injectors SHOULD go in the holes. i also advise getting a better quality hose. i had to pull the hose off the hose barb and the inside of the hose came out, its just low quality. buy a quality hose from NAPA. 5 bucks, its worth it. even though it was a pain in the a** i am still pleased with them. 4*s because of the lack of warning, low quality hose, and horrid instructions.

      Let put this issue to rest, these fuel rails work just fine with the MSD blaster copds. Originally when I bought the BBK fuel rails I had a authorized Ford dealer install them, they said they couldn't Install them because the injectors wouldn't seat right. My Neighbor is a Ex mechanic (Dodge) he insltalled them in 1 hr. So much for Ford mechanics! LOL

      does not fit bullitt

      It says these fuel rails fit a mustang bullitt. They do not!!!! The intake maniifold on the bullitt juts out over the stock fuel rails and ignition coils. These fuel rails are too tall and will not fit under the area where the throttle body connects to the intake manifold. Very misleading and made me very angry. Don't make the same mistake I did if you are a bullitt owner.

      Don't buy!

      I guess my review was deleted not sure, bought these last year and I wish I didn't. Poor fitment, hits the top of the coil packs. The worst part is having a constant worry that my car will catch fire from the injectors spewing fuel all over my engine. Used the spacers, took some out anything I try still fuel comes out of the right side fuel rail. Terrible terrible design will not buy anything bbk anymore. The rails feel secure but either spews fuel from the front injector or the back... my guess is because it's not sitting flush due to the rail hitting the coilpacks and thus does not allow the injectors to sit flush. Left side is perfectly fine and never had any issues with but the right side has given me issues since day one.

      Poor fitment

      I purchased this fuel rail kit, among other upgrades, and was pretty disappointed. The bolts that bolt the hangers onto the fuel rail were either too long, or the holes weren't drilled deep enough. I had to grind them down to get them to fit. Also, the bolts hit on the tops of the ignition coils. I am using stock injectors so I don't know if that's playing a part in the clearance or what. I did notice a power increase and good throttle response, but I did install a few other upgrades at the same time, so I can't quite narrow down the gains from this product.

      BBK Fuel Rails

      Overall this aid a great product. Well crafted, sleek, and straight forward. The fittment of the producing is quite tight. 1. The height of the fuel rails almost comes to the very top of the coil packs. Which means you are more than likely going to pull the fuel rails to change the spark plugs. On a forced induction application this will happen often. 2. The intake plenium is extremely close to the top of the fuel rail as well. I would recommend buying the intake spacer with these rails for more workable space under the throttle body plate. Overall I would recommend this product.

      If your looking for some bigger fuel rails these are the ones. Look good under the hood, and aluminum. Easy install took me about 45 min to install. You may need to bend the mounting brackets so the fuel rail sets parallel with the intake. But other than that a great product.

      This High Flow Fuel Rail is made very well. My Mustang is now considered very heavily modified and it was time to upgrade my stock fuel rail. (I also have their High flow fuel pump) After installing and setting tune the car is running much smoother and feel the extra torque this pony putting down. Overall great setup and great buy. You do have to do a little adjusting with the Coil packs with the install, but not a big deal in my book.
