Hello,

My gas tank indicator only goes as high as 3/4 when I fill up the tank. Do I need a new one...how do I fix it? Any tips?

Thanks, Greg.

Sounds like the fuel level sending unit in the tank is going bad.

Ours was something like that, went only half way at full. Found the float rod had been bent
somehow, was all whacked out, bent it back and worked fine.

First step is to pull the sender out and move it full throw and see if the guage reads full and empty. If not check the sender for proper resistance, 10 ohms full - 80 empty. Then for resistance in the wiring to the guage, should be near zero. If all that is good it could be the CVR.

Thanks, good advice. Do I have to drain the gas tank first? if so, how do I do that? Also, do I use some kind of sealer when I put it back in?

Thanks, Greg.

Yes, you need to drain the gas tank first. No sealer, just the rubber gasket that's already there. Wouldn't hurt to get a new gasket.

Most tanks have a drain plug located forward and on the passenger side. If not then use an electric pump to drain it.
