Thread: '94/'04 swap -- Fuel system

Alright, as some of you may know, I am swapping an L32 into my '94 GP. Wiring is like 2 sensors away from being done (finally!), so while that's in progress, I decided to tackle the fuel system.

I am going to assume that because there is only 1 fuel like actually attached to the fuel rail, that a stock L32 has a returnless fuel system. Since the 94 GP is good ol feed&return, is there a fuel rail conversion that is available to switch to my feed/return method? Any positive experiences from any1 who's done this?

If it fits over the Gen V blower, you could use the fuel rail from a series II engine. Just make sure to connect the vacuum fitting on the FPR to somewhere that sees vacuum and boost.

I had thought since the '04+ cars had a returnless system you couldn't do that swap...but I guess anything is possible right?

As long as it physically fits there's no reason you can't use the Series II fuel rail. Just have to make sure the FPR can see boost and vacuum and the engine will be none the wiser.

cool. I'll let u know how it goes. Thnx sabre. <3

alright, and going to another point I needed some quick help with, do you sabre or any1 else have a vacuum diagram for the L32 to save me some internet searchin? I found one for an L67 but i'm not sure if there is any major difference between these 2 engines vacuum flow
