Fuel Gauge not working ???

[NOSGT]

Recently my fuel gauge stopped working almost completely. It will only read up to about 1/8 of a tank and down, the fuel light also still works. I installed a new fuel pump about three years ago and its been working fine up until now, so I know i didn't mess it up then. No fuses are out, all my other intruments are working fine.... this one have me stumped.....

your fuel sending unit is bad, and you need to replace it, new for about $80-$115 bucks, or pull it out and fix it with a sealant if your low on cash, but you'll probably have to pull it again earlier down the road. By the way, its the other hole on the gas tank next to the fuel pump! comes right out, can do it within a hour!

so i have to drop the tank???

yes. also, if you start troubleshooting the wiring for it (i would, to confirm what is at fault), dont overlook the anti-slosh module. if the signal is mangled coming in or out of it, there is a good place to look.

good luck.

You wont have to take it all the way out just drop it enough to pull it out,might want to replace the rubber seal that goes under the lock ring,I didnt the first time and when I filled up with gas it leaked.

i would also consult a service manual for proper safety concerns. dont play around with electricity or spark (et al) around a gas tank, even if it is bone dry.

good luck.

And to add to the safety part as mentioned above,if you dont have the proper tool to remove the lock ring that holds the sending unit ,you can use a brass rod and a hard rubber mallet to take it off-dont use anything thats made out of steel-if you get a spark= BOOM not saying that would happen but it could.Its an easy job but be careful
