im installing my budget eturn system today and am not sure what to set the fuel pressure regulator at, any suggestions? im installing 80lb injectors, 2.9 whipple, sct ba 3000, jlt high boost intake, and running 93 pump gas.

sorry I can't help you with your question (though I hear 40 is a starting point?) but I had a question about the kit, how do you like it? do you think it automatically needs the upgraded fuel line? Looking at getting one by monday.
Any input appreciated!
Thanks and good luck!

OP, this is a question for your tuner. I have seen different tuners like to use a different base pressure. So ask your tuner and you should be good to go.
You know the process on how to set it right?
Stagedz, automatically needs upgraded? Nothing automatic about it. It is your decision. Some people have experienced fuel smell weep from the rubber hose. If that is a concern for you, upgrade.

Oh I totally...asked my question wrong...what I meant was are you getting enough flow with the stock line or do you think one should go ahead and upgrade to the 8an line that comes with the more expensive kits?
i cant really give you an answer yet, i just put the return kit in tonight and waiting for my whipple to get here on wednesday. the install wasnt too bad except the return line is a PITA to get on the fitting on the fuel pressure regulator and the fuel hat. its almost like the hose is just a hair too small to fit over the fittings. im going to be doing a remote tune with john lund since i dont have any tuners at all anywhere near me. i was just looking for a safe base pressure to start it up once im finished. looks like in going to be going with 39psi. thanks to can04cobra for the info.
It depends on the power you plan to make. I supported well over 700rwhp with stock feed line. If you want to upgrade the feed line, it is easy to do later. You will need a filter as well though.

Can anyone tell a dummy like me why an upgraded feed line needs a filter but the factory one doesn't?
The factory line has a filter, but it has a smaller inlet/outlet diameter then the upgraded lines. Why put in bigger lines if you want to restrict them at the filter?
That and the connections are different between the stock filter and upgraded line.
I usually go off 40 psi on gas and 50 psi for E-85. That is the starting point and can be moved around. I set my base pressure at 50 psi for E-85 and Ken B. said that was perfect. Since he tuned my car then I'll go with whatever the tuner says.
I spoke with Jon lund, he will be tuning it and he told me to set it at 45psi.
Cool, good to know...thanks for the info...im just gonna run a budget kit for now but I did go ahead and order the 405 pumps so I wont have to replace them in the future. If anyone wants a good deal on some Brand New GSS342's pm me :beer:
