    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.

    Was wandering what size AN fittings work on these fuel rails for stainless line attachment?

    • You will need an AN-6 fitting in order to install stainless steel fuel lines. I recommend the Russell Stainless Steel -AN Fuel Line Kit (87-93 5.0L), item # 56543, ( since these Fuel Lines already come with the AN fittings.

      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.

      Great Construction. Good Fit.

      The BBK High Flow Fuel Rail Kit looks and works great. The only feature that prevented a 5 star review is the fact that the fuel lines are rubber and not braided fuel lines. Thanks American Muscle for the quick shipment of this fuel delivery system.

      BBK Fuel Rails

      The overall finish and quality of the product wasn't bad. It's just that if I spend $170 on a product I would expect the hardware they supply to work. In this case it didn't. The supplied bolts to mount the brackets to the intake were to long and did not secure the fuel rails properly to the manifold.I also needed to enlarge the holes in the bracket that bolt to the manifold. They would not allow the rails to seat properly on the intake manifold. As well as the bolt to plug one end of the fuel rail. It would not secure the plug into the rail at all & at 40psi or more that would be a disaster. As for performance I haven't been able to test the set-up yet, but I'm confident that with the modification to the mounting issue they will perform well. Buy at your own risk.

      Look the part for now

      Rails installed nice and easy, good fit, haven't pressured up the lines yet so can't comment on any leak issues. hopefully none. Using an Aeromotive AFPR meant for stock Ford rails.. fit nicely. Rails look sharp and do not impede with injector harnass either. Would love to see some AN fittings and braided hose - not the rubber stuff that's supplied.
