I'm in need of a set of 50 lb injectors or larger. If I cant find a set, I need at least 2 GOOD 50 lb injectors. My car currently has 50 lb injectors and 2 of them are bad and right now I just cant afford a new set of 60's with a 5 year old and school starting back. Thanks

That's what I'm gonna try to do. Even when the 50s were first installed I was borderline lean at wot. I just noticed today on the body of each injector they were flowed in 2001, they're tired. Time passes quickly. My car would run 7.40-7.60s in 1/8 with the old 40 lb injectors and they were...

I just pulled the plugs and injectors #5 & 6 are leaking. Is it a coincidence both rears are leaking or is something else going on? Does anyone have 2 good 50 lb injectors they want to sell?

It's a 255 pump from Racetronix. Ill hafta check voltage at boost to make sure but I think last time I checked on Scanmaster it was 13.1. I'm still wondering why as soon as I turn the car off the fp instantly goes to 25 lbs then 0 after about 30 mins. The bad fpr I took off would stay at 40 on...

Ok. Thanks for all the input. I only have about 4 days per month to work on my GN due to work and custody of my son. When I check some of these things Ill let you know what I find. I'm ready to drive my car but won't until I know I can run it hard if I need to.

If I drop the tank how do I get the restrictors out of the return line?

I might take the fpr apart tomorrow and check it out

Just thought of something. I drove it to put gas in it today, it seemed like there was alot of pressure when I removed the cap. I've owned this car since 1988 and don't recall that much in the past.

Ill try to check them tomorrow. Which fpr do you recommend ?

Should've mentioned I installed new DENSO O2. Haven't pulled plugs to check, less than 500 miles on NGKs gapped at .32

I was watching traffic and trying to look at boost ,fp and scanmaster. I saw a steady 60 psi at 15 lbs. FP at idle was bouncing around 44-46

Is the return line issue or fpr gonna cause low O2 readings at WOT? Pressure seems normal at WOT

Wish I had known. Which regulator do u prefer?

Not yet. I'm guessing I could take it loose from fuel rail and blow air thru it?

They're still stock lines. How hard is it to change them and who offers a bigger return line?

C Chuck what was it doing or not doing before you cleaned it out?

The old fpr wouldn't hold vacuum. I couldn't get close to the correct O2 readings. Since changing the fpr those things are alot better and fuel pressure rises with boost. I'm thinking the reason the fuel pressure is dropping after shut down is the new fpr is now keeping pressure on a leaking...

I've been chasing a low O2 problem. Installed new Accufab adjustable fpr today replacing a 15 yr old ATR unit. It brought O2 numbers up from around 600 at idle to 777-789. AF 04,INT 128,BL 137,TPS .44, IAC 25, Turbo Tweak chip,new Racetronix pump month ago. FP set at 44-46 but it will not go...

I installed a new fuel pump a few days ago and noticed that there seemed to be a lot of fuel come from the return line. Ive never noticed that much in the past but its been a long time since Ive had the tank out and maybe its just normal. Im chasing a low O2 millivolts condition at WOT and...
