913, What should my idle fuel pressure be?
Posted by Greg, Jan-12-01 03:03 PM
I have the Vortech Fully Adjustible FMU and 440cc fuel injectors and I got it all in and started up the car and there was only like like 5psi of fuel pressure and it ran fine, I turned in the static screw and got it to 25 psi and it would not go any higher! I herd it should be like 38-40. Is it because my big injectors? What should I do? even if I turn the static screw almost all the way in it only reaches 25psi. I think my big injectors don't need that much anyways. And when I hit 25 psi at idle it chugged and then died. I have not drove it yet so I'm not sure about under throttle. I need to get my idle set first. Please help someone! Thanks!

I was told it should be arounf 40-42 psi, but that was with stock injectors. Being you have bigger injectors your fuel preasure will not need to be as high. I do not know forsure what it should be set at, but you can use use your Air/ fuel gauge for now to get an idea if you are lean or not. The chances are you are rich at 25 psi with those injectors. I would call a shop or the shop you got the injectors from that know a little about that and ask, if you do not get an answer you feel comfertable with here on the board. Let us know what you find out.
