Having a couple of issues with my fuel system :
1. I can't seem to get my fuel pressure below 9 psi, no matter what I do with my regulator. See attached pictures. When the adjusting screw is all the way in, or all the way out, no change in fuel pressure. Which, coincidentally brings us to problem number 2.
2. When starting my engine, I have my Holley Blue electric pump wired to a oil pressure cut out switch (5 psi op cutout). This in turn is wired to a toggle switch inside the car for manual on/off option. It's been working properly until today, when the switch wouldn't turn it on or off...even when I disconnected it completely
This has really got me perplexed. I do run the pump through a relay, battery feed, pump feed, ground, and hot line from relay to o.p. cutout switch.
Sounds crazy, but how could the switch work before, and now not ? I know the pump is pumping because I had a friend watch the pressure gauge. Bizarre.
3. This is the biggest headache. I run a Holley 750 dual feed, and I'm getting major grief over it. The problems started with gas geysering
out of the front bowl.
So I swapped the needle and seat front to back...voila, the back bowl is spouting now. Ok, buy new needle and seat and replace.
Guess what ? Now I've got gas gushing out of both the front and rear bowls.
I even replaced both
needle and seats front and rear.
Are they spouting because I can't get my fuel pressure below 9 psi with my regulator issues ?
suggestions would be appreciated. I've got to go clean up, as I reek of gas from my afternoon antics.
Just an example of how I had the regulator set. Motor not running in example photos.
regulator fully threaded in ...still 9psi
regulator all the way out...still 9psi
