This is a non return and the pump uses pulse width modulation to get x amount of pressure to the rails via a pressure sensor on the rail and a fuel control module. ****** retarded if u ask me but I'm sure there is a reason behind that just tryin to see what my options are before I just opt out and do a dual pump setup and rerun all new fuel lines and ditch the factory shiz.

 

Who did ur fuel setup? I need to figure this out soon my truck will be going in the shop for a trick performance t76 and a little cam action in about 2 weeks so I want to make sure I got everything I need beforehand

 

I did my own but mine is not a '07 i didnt realize they changed it from how its always been. I guess im no help at all. Good luck. Who ever is going to be doing your tuning may have the answer for you though.

 

Just wondering cuz I have no clue.... But would the fuel pump from a Camaro ZL1 work?

 

I did, but smokeshow gave me the idea...I just put an a340 pump in the bucket and y'ed it into the stock line. Then ran a wire to a hobbs switch and bam good to go.

 

Any way u could show me or draw me a diagram that actually sounds like something worth looking into I'm using a fuel cell at the moment but my stock pump drops right in so any help would definitely be appreciated

What i did is simple, i put an a340 in the thank, bulkhead fitting on the top of the tank -6an to the engine compartment, got a y block and a check valve to the factory fuel line which connects to the rails ( i have the fast rails ) the a340 is on a hobbs switch set to kick on at 3psi. So far so good no problem.

 

I wished someone with a NNBS truck would chime in and help a brotha out (BUMP)
