Find the fuel pump prime lead. It'* an empty green connector located above the battery. Get a piece of 8 gauge wire, put a 20 amp (I think that size) fuse on it and connect the battery positive to the lead. That should make the fuel pump try to run continuosly without the car running.

Sorry to interject here... why are you pulling a fuel tank w/o knowing the fuel pressure?

If your pressure is bad..you get to repeat it again.

First because a mechanic replaced the pump over a year ago with one from Kragens.
(I am not a fan of Master fuel pumps, and it has always bugged me that someone else worked on my car)

also the pressure/volume was poor. I dont need a gauge to see fuel only trickle from the schrader valve.

A Taxi cost me $40 to get the pump and it would have been the same if I went and bought a fuel pressure gauge. $40 Taxi + $40 Gauge. I havent needed a fuel pressure gauge in 47 Years so I felt no real need to get one now. I would rather take a chance and get a better pump.

So I knew from the beginning that I wanted a new Delco pump and screen.(no matter what)

When I removed the sending unit I noticed the pump wasent connected correctly to the tube (poor mount or installation) that would let the pressure leak out.

I installed the new pump and it fits very nice on the tube and now I have piece of mind as well.

I will install the tank tomorrow and see if it runs.

Has anyone here ever needed to replace the fuel pump relay?

Sorry...I missed the low volume low pressure post. and agree on your approach once you knew it was an issue.

Holler if we can help further.

On the FP relay. It'* a relay..so it can go bad, however your small amount of fuel would make one thnk it'* working. You could pull it, test it for continutiy in the energized state.

I have seen the contacts in some relays get carboned and while the relay engergizes..it can be making poor or no contact if the build up is too great. Although I haven't seen that in normal automotive relays to date.

No prob at all. I really want to say thanks for all the advise i have received here, it has reminded me why I became a mechanic in the first place.

Heck..I wouldn't swap. I'd run power and ground to test for it reacting and then test for continuity

FIXED! I almost forgot how excited I get after I fix stuff.

before when I turned the key to on I could here the pump go on to pressurize so I could hear it run.

when i depressed the schraeder valve there was very little pressure or volume for that matter. But for me to get to the store to buy a fuel pump gauge it was almost as much to get the pump (Taxi Ride).

So I FINALLY got up the nerve to remove the tank and noticed the pump wasent seated well on the tube I was hopeful that was the problem (technically the fuel was just leaking back into the tank and wasent able to pressurize the line correctly.

So swap the pump for a new Delco, install a new sock and filter, replace the tank and VOILA!

BigRed is alive again.

Thanks to everyone here that took the time to read the thread and offer advise.
