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.

I don't see where the AN size for the rails or the hoses are listed. What is the Aeromotive AN size of the rails, and hoses. Stock is AN 6.

Las97GT12

  • The rails in this BBK High Flow Aluminum Fuel Rail Kit are 9/16" and the hoses are 3/8". The 9/16" thread on the rails and the 3/8" diameter of the hose are both equivalent of 6AN.

    I Installed these for cosmetic purposes only and they look great. I'm not sure where these other guys are saying they gained more power by installing them but whatever. 42 LB injectors? Are you supercharged? There is no reason to put larger injectors unless you are changing cams, intake, heads or installing a supercharger.

    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.

    I ordered this part because the dealer wanted 336 for theirs and another 335 for labor to install it. This part increased my MPG and the amount of power is unbelievable. Especially love the look of the blue when the hood is raised. Awesome.

    Awesome!

    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.

    More Fuel? Yes Please!

    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.
