Fuel gauge not accurate...

Mine has differen't connections and a pressure sensor on the top. That one i don't believe does.

Is the pressure sensor itself in the plate that fastens to the tank? Reason im asking is because the new unit reuses most of the module. you remove the original fuel gauge sending unit and the new one bolts in its place on the fuel pump module.

It's on the top plate external to the tank. there is a set of wires that goes to fuel pump and gauge, then also a pressure sensor for EVAP i believe.

its most likely the sender, the off brand ones can do odd stuff when the contact points get worn. I had one that would work just fine but when the fuel in the tank would slosh around the needle would freak out spinning around and smacking the oil pressure needle below, all it was is the sender in the tank. switched to a delphi sender and it works perfectly now...

here's a video of the crazyness I took when I was trying to figure out what the problem was.

Mine doesn't go anything like that. It just doesn't read accurately. at all. I wish i could just drill a new hole and add another one.

LMFAO thats hilarious! mine just maxes out pointing to the right

 

[JonZ71]

atleast its moving with the bass ahah

heh, yeah, its hard to see, but when the oil pressure needle twitches, its because its getting hit with the fuel needle.

mine was an extreme case, I'd still put my money on it being the sender judging from your description

 

[JonZ71]

Yeah i just gotta find out what to do with it. im trying to find a GM unit for cheap

LOL! GM Part + cheap, don't usually go together in the same sentence!
