fuel gauge has lost it

[TheLonelyIsland]

bought a 91 nissan king cab today , on the way home i put some gas in it , 3/4 of a tank and once it got to half it dropped instantly to 1/4 and didn't come back up.....what could this be? other then this the truck is perfect! can i do this repair by myself? mechanics are rip off artists....most anyhow.


anybody got any idea?
thanks

Probably the fuel sending unit that is in the tank.

It could be a easy driveway job.

I would guess there are 6 bolts holding the box onto the frame, and the gas filler gauge, and electrical would have to come out. But seriously... A mechanic would know best. You may think that they are just there to rip you off, but they go to school for that stuff.

Learn how to fix ch!t yourself or pay people to do it for the rest of your life.

Sounds like a good plan. They can do tests on it too to see if that really is the problem. Not just some guys on the internet saying what they think it is.

run the truck low on fuel , pull the tank 2 staps , spray wd40 on the treads 2 day before the job starts disconnect filler & vent hoses wear safty glasses you'll get crap in your eyes price out the parts first you may need more than 1 paycheck

Joey, this is all good advice, but lets start with something easy....the truck my kid just bought (King cab) had the same problem. The guage defaulted to 1/4 tank regardless of how much fuel there was in it.

Very simple fix.......empty the tank, syphon if you have to, reove the straps, as instructed above, the wiring conections are on the top of the tank. The ground wire corroded of Brents. We made a new connection with a new crimp connector........presto. Whole job took less than 2 hrs, with air tools.....double the time without. EASILY fixed in the driveway
