        don’t waste your time

        Don’t do it! Do not waste your time or money on this product. I read the bad reviews on these rails and still purchased. Install was easy. Fixing the multiple leaks wasn’t even the issue. Dealing with a pressurized system with so many removable sealed parts, leaks were expected. The only leak that could not be fixed was the fuel pressure regulator mount where it meets the rail. It is a very VERY poor design. The wonderful people at American Muscle informed me that it is a known issue and that there are mods to fix it. I do not want to modify something that was designed to fit my mustang. Please stop selling this poorly designed fuel rail. I would like to see something better. I suppose it’s back to the stock rails until I find a better solution. Thank you American Muscle for allowing me to return this!

        leaked on every single injector

        installed this fuel rail and did so correctly, i have installed fuel rails on my car many times and others, the seal with the injectors leaked on every single port except 1 and was a pure waste of time. the fuel pressure gauge housing does not clear the ford racing intake and throws it off a few mm. as well. went back to stock fuel rails and am now stuck with these.

        Had some hiccups

        I will say the customer service from American Muscle is wonderful. Pro’s- great finish on the fuel rails. I like how the fuel hose is hidden behind the intake manifold. Super easy instal, follow the instructions;) Cons- I found out I had two bad 9/16 18 inch thread pitch pushlock swivel fittings. I ordered two non swivel fittings from summit. After I replaced the fuel leak.

        not quite what I expected

        do not like small screws to hold fuel inlet part;also Would not directly line up with stock inlet line;also no clips to hold injectors to fuel rail;fuel line to connect to fuel rail on opposite side of engine a bit short and do not like barb style connections...prone to leak...would have to have a stainless line built

      will this work fine with my 2005 gt some write-ups say to use with high power cars......can i use it on my mildly modified n/a 05' gt ???......AND how many hoses are in the hose kit, please

      • Fuel rails can be installed on any motor, stock, mild, or highly modded cars. You will see no benefit on a stock or mildly modded car other than aesthetics. It should include one hose which is the cross-over. Your stock fuel line connects to the fuel rail. No other hoses needed.

      will they fit a wipple super charger I have a wipple twin screw super charger. will they fit on that or am I stuck with the stock fuel rails

      • Hi,This BBK High Flow Aluminum Fuel Rail Kit can be used with a Whipple supercharger since you use your stock fuel rails with the Whipple, and this fuel rail kit is designed as a direct upgrade replacement.

      I recently purchased and installed these fuel rails. I'm having an issue with the seal from the pressure sensor and the PS bracket/plate/adapter. Tried new o-rings on both the PS and the one that sits between the rail and bracket. Still leaks... How can I remedy this situation?

      Can you return these if they turn out to be bad? its has mixed reviews ive read. From leaking to working fine.

      • You can return the fuel rail if it is found to be defective, or if it is uninstalled. We recommend a professional installation as AM does not cover damage as a result of a bad installation.

      Would it fit with a roush r2300 tvs installed? Because roush uses different fuel rails than the stock fuel rails.

      • Unfortunately we have not tested the BBK High Flow Aluminum Fuel Rail Kit with a TVS supercharger to be able to confirm fitment
