take it back and get the other one for lt1. one is up one is down. this is what yours should look like. http://shbox.com/1/fp_reg.jpg

 

Oh that sucks....I bought one off a running car....A friend at the parts store knew a guy...lol, So we went over and I bought it and the guy took it off....I never paid any atten.t to it He was parting it out since it was totalled from the rearend.

So there no way to rig it up just to check to see if that was my prob? If it proved to be my prob Id go buy a new one.

 

never though about it,,, have a look at it and see if it looks like theres a way to hold in on there. would be a bummer if it came lose and sprayed gas all over and poof.

 

Well, I went to work and cut the old bracket off, and made one to wrap around it so it wouldnt move....but anyways...

With the stock one on, my fuel pressure went from 25-30 to 37-40. and it hold the fuel pressure for a will when it shut off. Guess Im gonna buy a new FPR. Now when I remove the vaccum line off the pressure goes up alittle, is that normal?

and at idle its at 38-39 lbs, and if I rev it to about 3-4000 it drops to about 30lbs, how quickly should it rebound back to normal?

 

when you throttle up the pressure should go up to 40-42 lbs. something is goin on. fuel pump or fpr or injector. the used fpr may be getting tired.

 

It would drop with the accel regulator also...i drove it down the road....done good....idled good...didnt flood as....but after 3 gears of hard throttle it, when I tried to give it some throttle it acted like it was running out gas....it could be...but that could be from pressure droppage also, right?

 

yes the computer will also try and make up for it with longer signals to the injectors. how old is the fuel punp?

 

No sure. but i have 2, for the nos system... i flipped the 2nd one on and it didnt help....i actually could be out of gas tho....its laying on E..lol

 

Opps..sry..im on my phone. I meant, Not sure.

 

are the pumps in line or is there two pickups? you may have air getting in there or if in line one pump interfering with the other. oh and you may be running out of gas. lol that might be the most expensive fix
