Walk me thru some fuel upgrades.. Regulator concerns.
For some reason, I have researched every possible angle of these crazy F cars (LSx) just not the darn fuel system. I was tech talking w/ my ASE Cert Master Tech of an Uncle, and he asked me what fuel pressure regulator I was going to settle w/... I couldn't answer that Q.
Ok. I have a hook up for MSD parts.. (I'll explain that at a future point, got some stuff in the mail.. *crosses fingers*). I am looking to get some 42lb injectors soon and some high flow rails from LS1 Speed (I buy all my parts from them).. I am also about sold on a Racetronix system for next year maybe.
Regulator recommends? This is for my 2000 Z28 BTW. I am running roughly 400FWHP on current mods. I can't fit all my mods in the sig, no internals yet. LS6 intake, full EXH, 160 stat. -Basically.

I've had pretty good success with my adjustable boost referenced Aeromotive reg. Granted it's for the LT1, but i'm sure you can get one for your LSX. You gonna run your setup over at Area 51 in Roswell when your done?

Our car club will be planning 1/4 mi trips and dyno days soon. We really need to get organized.
I have done minimal reading on the LS1 fuel system. I know it has a constant 'bath' fuel pump in a bucket. The unused fuel is used for cooling then spilled over back into the tank. The bowl also serves to provide fuel to the pump during high 'g' corners, braking/stopping. I am unsure about the return side of the operation.
I'll have to dig up some GMHTP archives I have stacked in the corner of my living room.

^ huh.. Come to think of it, I only have a supply line under the hood. The other is for the EVAP system. THe regulator is between the fuel rails, from what I understand.
That seems like an odd system not to have a return. ... I'll have to do some reading when I get time. How in the heck does that regulate fuel pressure then??? Regulate what hits the injectors I guess..
