        Cheap rails disguised by a high price

        These seem to be Cheaply made. They came poorly packaged and all scratched up (I wasn't worried about appearance since the intake will cover them anyways) These don't appear to be the same rails that are pictured... but similar enough. The fittings were very difficult to install, but nothing a vice and crescent wrench couldn't fix... and as I had expected... as soon as i pressurized the system, the rails leaked EVERYWHERE. Nothing I did could prevent this from happening. The worst part of the rail is the cap at the front of the driver side rail... no threads are in place for the option of a plug... so just an O ring and a screw on the corner... of course it leaks! Absolutely a waste of money and time... DO NOT PURCHASE! These are not the same quality that they use to be!

        Good product. Fast shipping and good price on shipping. Great guys here at American muscle. Way better than CJ Pony parts. Part was Stock replacement with no extra modifications. I have a built 331 and it was a perfect compliment to my build.

        Good fuel rails for the money.

        These fuel rails are designed to be used with the stock lines. However there is no reason why you cannot buy the NPT to AN fittings to convert them. I bought a 1/4"NPT to AN-6 and a 3/8"NPT to AN-8 for about $10 a piece. One draw back I see with these is that there isn't a good way to check the pressure at the rail. I am going to try and tap the aluminum plug by cylinder #5 and put the factory test port in it. The second draw back is that there is no fuel cross over in the front of the rails. This is why I want to check the pressure at cylinder #5.

      How much hp can these fuel rails support?

      • Overall hp support will depend on the brake specific fuel consumption (bsfc) of your build, as there is a large range depending on your individual build. On average these should support over 1000hp, but may be limited depending on the rest of your fuel system, such as the pump, lines and regulator, as well as the bsfc of your engine.
