Fuel Sending Unit Repair

[RnR]

My Grand Prix hasn't had a functional fuel gauge in quite awhile now and while researching the issue, I came across this outfit that apparently repairs sending units...

http://www.fuelsender.com/services.html

Has anyone had a good/bad experience with them?

It could just as likely be the instrument cluster.

I'd be inclined to suspect the instrument cluster if the guage was totally dead, however it comes active on occasion (but never accurate). Just a suspicion on my part, but I think the issue is back in the tank.

Getting out the sender maybe easier said than done. Does the tank need to come down or is there an access panel? When I went to replace the fuel pump on my Suburban, the steel lines coming from the fuel sender snapped when unscrewing from the flex hose. So now I had to replace the sender assembly also. Can this place fix that also? And you should replace the fuel pump and sock if you are pulling the sender assembly if its part of it.

I had to replace fuel pump a 2nd time and it was much faster the 2nd time and nothing snapped.

It's accessible from between the two rear seats. I've already been in there once to vacuum the top of the tank at the pump location. (BTW - it was filthy!!) So no, the tank would not have to come down. Tried reseating the electrical connections, but that didn't help any.

The company appears to be quite practiced at refurbing sender units... check out their site and pics.

Can you put a resistor or potentiometer that simulates the gauge in line [unplug the sending unit at the tank]? This would show if the sender or the wring/gauge is bad.

Probably could... do you know specifically where I should be placing it; connector/pins? (1999 Pontiac Grand Prix)
