I'm using stock fuel rails. It has worked fine for the last 2 years.

Jody,

It looks like he ran a new supply line after FPR to the fuel rails. It looks like it is a -6 line. I think we have that size intlet fittings on the rails so it should be a more or less direct hook up.

As far as connection 1. He probably cut the line and flared it and then put a flare to an adaptor on it. DKPhoenix correct me if I am wrong.


Is the higher pressure he is reading at his rails a common problem with running a larger pump and billet rails???

I think you are thinking of a pressure relief on areturn style system.

I Agree. A return style regulator should be run after the rails. You want to regulate your fuel pressure after the rails to correct for pressure drop.

The two ports on the sides of the regulator are inlets, which should be attached to the fuel rails. The port on the bottom is the return, it should go to the fuel tank. If you're not using one of the inlet ports, it can be capped off or plugged.

I don't quite understand how you would use this return style regulator in a non-return type system. The regulator has two inlets, and one return. There is no outlet to go to the rails.

There will be a pressure drop across the rails. That is why you want to regulate it after the injectors.

Is there any onther FPR that might not be so confusing? I mean, one of the vendors has to have some kind of kit..

Yea, I see that one is an inline with only 2 conections.. I guess ill contact summit on teh return policy. Thanks. AEI-13105 is the part number at summit, anyone ran this one before?

Well, I just talked with Nate over at Nasty Performance. And what I understood was, if you run the regulator before the fuel rails, you will need a return line.

The proper way to do it he said was to run the fuel line, exiting the other fuel rail, and back to the tank with a no return line FPR somewhere between. He said I could use mine like that and cap the other end..

That is the one I have (except I have the billet version tho). If you do a search, I have recommended it a few times before on this site

And where would you put that one?

LOL after the fuel rails, and you need a return. I used my evap line as the return...

Thanks C5Fire, some good info.

Well, here is how it looks.. Everything went pretty smooth and ran the hose all the way back to the tank. Still need to get the 90* going to the fuel noid though. Part is sitting on coffee table just have not had time to hook it up yet. So, I hope there are no nasty leaks.

There ya go! Looks nice

If it is like on a drag race car the regulator controls the amount of fuel going back to the tank. If it is after the fuel rails, it can release only enough fuel that the pressure at the rails will be the required amount. The pressure between the regulator and the tank could be substantially less.
