I cant seem to find the problem the guage, always full. When I remove the connection from the tank the guage drops to zero. I cleaned the contacts but it will still reads full when reconnected. Mine is an 87 (951) any advice???

Sounds like your sending unit took a proverbial crap. the gauge works, the sending unit I believe is just stuck.

Could I have also lost a ground some where?
If so where would I find it. I know in the 87+ the ground is under the dash I just dont know where to look.
I will also check the sending unit.

IIRC full ground is when the tank is full, then using a variable resistor in the sending unit, tha gauge drops as fuel level drops. This is why the gauge drops after you lose the ground/unplug the connector. I am speaking generaly on modern vehicles, Pcars should not be too different.

thank you
one of many projects.
Have you ever done a rear main seal???

Spidey944

Same procedure as replacing the clutch. If you can't do it yourself, you can buy a lot of oil for the cost involved with paying someone to do it.

im going to give it a shot (clarkes) will guide me through
any advice ( doing clutch at the same time)

what are the odds of the seal scoring the crank??

Spidey944

Next to none I'd imagine. If the rubber is completely gone off the seal then maybe i guess, but should be OK.
