gas gauge reading wrong??
I just recently installed a new gas tank sender while the bed was off but I filled up tonight and it only took 8.1 gallons and the gauge was reading under a 1/4. That's not right is it?? I have a 79 reg. cab short bed and the tank is at the very back.

There are several different types for the aft axle tanks, it depends on the year, whether the tank is steel or plastic (please don't say you got it from lmc!).
If you can only get 8 gallons or so in the tank, it sounds like to me that the vent hose is pinched. The vent hose was taped to the fill hose originally in three places.
This prevented the vent hose from collapsing.

I'm having this same kind of problem. for example last week I filled up. I let the pump shut off. it said 8 gallons. when I got going down the road it never went above 1/2 tank on the gauge. now I'm driving around and the needle is sitting below "E".
I have been noticing the guage is messing up.
no, I didn't replace anything. this is the way I bought the truck.

Where did you get the new sending unit from?
