every other week or so mine will go from full to E when i start it and sit on E until i turn the ignition off and back on again then it starts working fine again. Not that that helps solve your problem just one i have been having.

 

Just throwing this out there...

I bought a Dodge Dakota a while ago and I was told the fuel pump had recently been replaced. Soon after I bought it the fuel gauge got stuck on full. I pulled the bed off (MUCH easier than dropping the tank btw) and found that when the PO installed the sending unit/fuel pump, he didn't put it in perfectly straight. This caused the float to hit the side of the tank and stick, giving me a false reading.

 

^thanks for the input, im gunna frig around with the tank later today

 

Good idea,...I'm leaving mine until the spring time...my garage is slowly getting cleaned up...but I still need to locate/buy a wood burning stove, install chimney pipe,... and wire the whole garage. A lot of work yet...and last night it was -38 C with the wind chill,...BRRRR!!

 

that is cold

speaking of fuel readings, i got 150 miles of of a quarter tank of fuel (from full) all 2 lane highway at about 60 or so, seems a little odd to me

 

Mine too,...I put in gas, the guage shows just over 1/2 of a tank.. and I drove 230 miles this past week,...according to my trip meter,...and I still have over 1/4 tank! (I just throw in $10.00 here...$20.00 there...not really sure how much gas is in there). I'm scared to fill it all the way up due to the "deer" that hit the truck when the last owner had it....and I don't know if it will leak?...I don't smell gas but the side where the filler neck is was pushed in a bit, (about 7"), and he pushed it out some....but I'm not sure about the filler neck. Too cold out to go crawling on the ground...plus I'm 6'-1",...232 lbs.,..I'd have to jack it up...I need my garage!

 

thats normal for me...usually i go 125-150 miles (from full) and it only uses a bit less than a quarter tank...its always done that so i believe its acuarate...its weird though

Also i just relized that since ive done a part of my rebuild, and i filled it with Super Mobil gas from empty for the first time, and now the gas gauge just dies...now is it possible that the more "potency" in the gas could have killed the sensor?

 

If you've never "filled" the tank,.. from empty especially,..the float mechanism could just have crud in it?....or damage..from wear?...many variables. Only thing sucks is having to take the tank out for such a simple fix proceedure.

 

Don't drop the tank, just remove the bed. Trust me, it's a whole lot easier. Just undo the 6 (or 8, I don't know exactly how many there are) bolts holding on the bed, unplug the taillights, remove the fill tube (4 or so screws), wrap some shop towels around the corners of the bumper so you don't accidentally smash the bed into bumper, and get 3 or 4 friends to help you left the bed off. Once the bed is off you have full access to the fuel tank. You don't have to drain the tank, and when you try to fix whatever is wrong with the gauge, you don't have to reinstall the tank every single time you want to test it out.

 

I get that with my v6... thats bad for me or good for you.
