`83 fuel gauge problem

[68c10owner]

So my 83 C10 has dual tanks. I only use the left tankWhen I first got it the fuel gauge would`nt go past half tank. Now it wont go past 1/.4 tank. I decided to start using the right tank thinking at least the guage "should" work. Well it still only goes to 1/4 tank. Is it a sending unit issue or is my gauge bad?

I had a problem on my 82 gas gauge with dual tanks. Regardless of wich tank it was on the fuel gauge would read 1/4 when the tank was full and read empty when the tank was empty. I install a new gauge and now it works properly.

Thanks. I was afraid of that. I really didnt want to crack open my dash but Id like to get the fual gauge working. Its the only one that doesnt.

You don't have to remove the whole cluster to change the gauge. Just remove the bezel and lense to get access to it.

Ok Thanks. I thought I had to pull the whole dash out. I havent had to mess with the dash stuff before so Ive never had one out.
