82 BRAT gas guage full??


Recommended Posts

I put my brat partly back together tonight because of the issues my 87 is having.. it needs to be ready to take me to work at a moments notice. But tonight when I started it to make sure everything still worked (ive only put like 300 miles on it in 9 months) the fuel guage read full!

 

I had removed the battery a while ago and used it to move the 88 into the garage and then put it back in.. but anyway the brat SHOULD be near empty.

 

Since the last time I really drove it I yanked the bumper and stuff... do you think I loosened a wire while crawling around under there? Or is it more likely that I just need to fill it with gas and let the guage figure itsself out.

 

I'm hoping its the later, as the fuel guage really never was all that accurate since I only drive it once every 2-3 weeks.

I am not 100% sure, but I think that when the wire going to the sending unit is grounded, the gauge should read full, and the sending unit on those is on theback of the tank (look underneath and you will see a round thing with like, 8 phillips head screws holding it on, with a wire coming out of it, that is the sending unit. Pull the wire off and ground it, gauge should read full, apply 12V and it should read empty. it MIGHT read the other way around (ground = empty) but I am not positve. Turn the key on and unplug the wire and see if the gauge changes posistion... That would help to isolate whether it's the wire or the sending unit...

Your tank could also somehow be full of water, if the tank is rusted out on top, which could be the case as much cancer as that thing has..
