ok for anyone following my nitrous thread, this will be repetitive, but i need to get some broader impact...
I just got the car running yesterday, new walbro 255 fuel pump installed( don't even bother on your car if it has over 100k on it, at least not in our rust belt)
i broke all 3 of the lines going to the tank, and replaced them with rubber fuel hoses, and just barbed the lines. dealer cost for just one of the 3 lines i broke was $130, thats a 12 inch line or so, so i did them myself.
so after the second time i dropped the tank, all the lines are repaired, and the fuel pump is working.
now i've got another problem..
fuel pressure reg has been giving me a few issues. i've gotta be honest i don't know how to tune it, but it didn't come with instructions besides which is input/output.
it's an ebay billet FPR
does turning the adjustment in restrict, or allow more fuel?
and how should i go about tuning the FPR for use with the car.
Fuel pressure is reading like 50-60psi on the gauge, regardless of where i turn the screw, seems pretty high to me.
i went out and drove the car today (first time in a year and a half ), and when i got on it, the fuel cut off around 5500, and there was really no power in higher RPMs, so i brought it back to the garage, turned the FPR in a couple turns, and now the fuel shuts off around like 4k, but it runs good under 4k, good power in midrange 2-3k. so my guess is i'm having a fuel delivery problem, not enough fuel. might be the FPR i dunno. also, i did a timing belt before i put the engine in the car, so there's a possibility that the timing is off, but seems to me, that if it was off by a full tooth it wouldn't run good at all.
i need to get the car running good under normal circumstances, then i'm putting the nitrous in!
anyone know about these FPRs, and what i have to do to tune it correctly?
