Every time I fill up my car the gas gauge only goes a little pass half a tank. Anyone know how to fix this so that when I fill it up it actually shows a full tank in the cluster? I have a 94 rs

 

First of all, you need to make sure if your gas tank is filled. Integra takes around 13 gallons to fill up completely. Just borrow a friend's cluster and swap it in with yours to test if your cluster is reading properly. If not, then you'll know it's not your cluster. Always start with ways that doesn't involve spending money first.

 

Has it always been doing that? Did you just get the car?
