Truck intake on LS1
Truck intake on LS1 I'm swapping stock ls1 from 2000ish camaro (i think) with 230/230 cam into a 1994 bmw 318is.
In the process of buttoning things up and then getting it tuned. I figured it wouldn't be a bad idea to swap the stock LS1 intake to a truck one for extra torque.
What do I do about the fuel lines. The truck intake that i got doesn't seem to have a fuel regulator(or whatever that regulator looking thing between the rails that ls1 has). Is that something that I need to address or is the fuel can be controlled by stock ls1 ecu without the regulator? I.e just plug the fuel in and thats it?

Yep, the early LS1 rails had a dampener and were regulated at the pump (f body) or with an external filter/regulator (corvette). Early truck intakes had a regulator in the rail and a return line. Later ones, only an inlet. If your truck rail has no regulator and return, you'll be fine as long as your pump is regulated.

I was under impression that all I have to do is connect fuel in, and the fuel vapour return line(not sure the actual name). And cap off my existing fuel return line on the car and good to go.
Guessing that's a 411 ecu. And I have no idea how the bosch pump is regulated or the pressure it puts out. Most GM efi pumps put out over 90 psi, but use a regulator to bring it down to the 60psi that the LS system requires.
Also note, I think some systems use pwm from the ecu to regulate pressure, so just because the bmw may be rated at "x" pressure doesn't mean that pump will put that out with the 411 ecu controlling it.

I think i figured it out may be. I need the corvette pressure regulator/filter piece. https://www.speedwaymotors.com/Speed...PSI,41791.html.
I connect that to fuel in and return lines and run one line to the engine for fuel in. And the vapour line from the engine back to tank and im good. Thanks guys.

I did a 99 E36 swap and used the C5 Corvette filter regulator. Per the guys on Bimmer forums the stock BMW fuel pump will work on a stock LS1. I upgraded to the 255 pump.
I don't know if the truck intake will clear your hood. It a bunch taller than the LS1 intake.
I had 3.91 gears in mine and there was no lack on torque. Besides the LS1 intake looks so much better. Those truck intakes aren't very pretty.
Here's a pic of mine.

Good call on the walbro i actually have one somewhere I just forgot to install it.
Ima shave the intake and cut the hood. It'll look ok.
On a sidenote does anybody know if i need these weird injector caps/seals from the injector ports on the truck manifold to install the ls1 injectors?
