[none]

i need help on what fuel rails will fit my my 06 mustang gt with a kenne bell 3.2 supercharger i m looking at the fore rails but not sure there going to fit so what are u guys useing on the kb thanks

Why don't you think they will fit?

This is on a Whippele manifold... the Fore rails can be set up in a number of configurations so fuel lines should not be an issue. I have moved the pressure sensor to the drivers strut mount and run a distribution block instead of a crossover.


I mean if they accept the stock fuel rails they should take any replacement rails out there, no?

kenne bell has a issue with the aftermarket rails hitting the bypass valve

If I remember correctly the clearance issue had more to do with the fuel line as opposed to the actual rail. But I believe Metco makes a flat style rail as opposed to the round style Fore rails. But if memory is correct the problem was solved with either configuring the fuel line to the front or using a 180* connector into the rail by the bypass valve. Also you might check if they produce a "drop down" kit for their rails. You'll have to get shorter injectors but I think I've seen it done on Hellcats.

its the fuel rail that hits nothing with the line i got areomotive rails and i have to grind 3/16 off the rail where it hits the bypass i just dont like the rails dont have a spot for the presure sensor

I put my sensor on the distribution block I used to feed both rails (2nd pic) but I rerouted my fuel lines into a dual feed set up. Are you using a crossover or feeding each rail separately?

im feeding each fuel rail seprately im feeding the fuel rails in the front and plugging both back ports is that a good setup

That's what I did. Where did you mount your rail pressure sensor?

That's a massive blower. How much hp are you expecting ?

i didnt mount it yet but with the fuel rails feeding from the front and both ports plugged back of rails what is this set up called and there is no return to the tank?

It's called a return less system. It regulates pressure by reading the sensor and cycling the fuel pump(s) as needed to maintain rail pressure. unlike a return system that runs the pump constantly and uses a regulator to maintain pressure.
