Fuel Gauge Problem?

[HotRod73]

My fuel gauge seems to be sluggish... when im driving i really cant tell how much gas i have unless i stop. sometimes i can. it just acts slow and fluxuates alot. what would fix this? a new guage? new sending unit? im sure its common on these trucks..

Yep.. that is pretty common as far as my experiences have been. They normally fluctuate at quick accellation or stopping... in short "ALWAYS". A fix would be nice... but I'm not for sure of one.

I checked the ground wir eon mine, cleaned it's connections and plugged the ground wire back on the stud, and crimped it around it pretty tight. it really helped stop it from jumping so bad. Doesn't jump around alot now.

lol thanks, I se them mentioned alot on montecarloss.com which I'm on all the time. My monte was my project while we drove the truck, now I'm just about finished except for things I want to do, it's all driveable and xcrap so it's not have to anymore just want to, now it's time to try and fix up the truck which is being a PITA.

thread unjacked LOL.

Also, I changed the dash guage cluster out because I had already changed sending units for temp and oil and they didn't work, plus my fuel guage jumped like crazy, so i changed it, and cleaned that terminal on the unit up, crimped the wire connect onto that terminal good and tight and it didn't jump much at all anymore. I say clean connections and make sure they are almost impossible to move, then see what happens.
