SARD FPR in a returnless setup - do I have the right idea??

[savage1987]

I reckon i might have to set fuel pressure with a gauge in the FPR, then once I get it set to 60psi, depressurise, remove gauge, replace gauge with fitting to returnless line to engine rail.

Sound about right?

I can scan up a quick sketch if that was stupid or confusing...

why does it have to be returnless?

[savage1987]

Want to use the factory LS1 rail if I can get away with it, and I have been told by a few people it's easy as anything to set up. Don't know enough about the two options to make a proper list of pros and cons, only thing I know of is fuel temp is higher with a returnless setup but I'm running it N/A so I really don't think it'll matter too much..

Thanks, good read.


Looks like I'll need another 8mm nipple for the SARD reg since I won't be running a gauge from it.. are these readily available anywhere?

Enzed or Pirtek will surely have something suitable.. I've always bought my barbed screw-in fittings from there.

From LS1 forum

This is what I'll be doing:

permanantly fit a gauge
helps heaps down the track if u have to diagnose a prob

easiest way i describe a fuel sytem for ls1 ls2 etc is

from efi pump run high press fuel line directly to motor

now anywhere along that line cut it and fit a t piece
off that t piece run a hose to a pres reg then from reg back to tank

preferably back of car is best spot for press reg as its out of the way
but if u have ti fit it in engine bay it still works the same

some press regs have another fitting so u can fit a gauge
