Fuel System

Hoping the LS swap experts can clear up my confusion here:

I was planning on using a new stock tank with the Vaporworx insert to operate a 2010 - 2015 Camaro SS or ZL-1 returnless pump. My LS3 arrived yesterday and while reading the installation instructions it occurred to me that perhaps the E-38 ECM doesn't support PWM fuel control and I may be hosed (no pun intended). All of the GM diagrams I am looking at show a return line which I was not planning on.

I know just enough about this stuff to be dangerous so just trying to clarify what I can and can't do. I believe I can add an aftermarket PWM controller but would prefer not too. Should I just abandon my return-less system or am I off track here?

You'll need the control box from Vaporworx in order to take advantage of PWM. You'll use the wire from the ECU as a signal wire to turn it on, the control box will take care of the rest.

Re: Fuel System

You can use these if you donít want to use the Vaporworx PWM controller. Gives you returnless 60 psi.

Don -

I actually purchased those pieces to go with the pump I bought so maybe I am good to go? I really only decided to go this route because I had a brand new tank which I had purchased when I was going to go the stroker route. Then I went to the dark side, I mean LS side and thought it would be nice to incorporate my tank with an in tank pump (saw this on Pro-Touring forum) and here we are.

This is what I have so far:

Yes you are good to go. Just use your relay to supply constant 12 volts to the pump.
