stupid fuel gauge
 

hey guys ive researched trouble searching on fuel gauges but this ones got me twisted. 6 months ago I put a new sending unit in my blazer. so I could see how much gas I had well recently it started to mark 1/2 no matter what was in the tank. and every so often it would mark correctly and then go back. well the last 5 days its just stayed on 1/2 tank. i know i have at least 3/4 tank. i switched the fuel gauge and same thing. any ideas? i bought the sending unit at oreillys they aint to fun to put i either LOLthanx

I'd suspect the sending unit again. The new floats are garbage.

oops I just called oreillys I guess ive had it a year and 2 months now dam throw away parts.

Went through that sending unit issue with the bad float on a 68 last year, replaced it twice and the new junk wouldn't work a day. It would be nice if you could spray them with something to seal them that wouldn't dissolve in your gas and foul it up.

was reading on another website were guys just cut a access hole in the bed instead of removing the whole tank. this sucks cause I really enjoyed having a fuel gauge

Not discounting new equipment being junk, but did you check your grounds. My '79 K10 used to read 1/4 no matter what. I installed a new ground from tank to frame and the gauge has been reading true ever since. With any electrical issues,gauges incl., 90% of the time a ground is the culprit. Cheap fix first.

Thanx I'll check that out funny thing it started marking a little less than 1/4 of a tank and it was right but after a fill up back to the center it went

Re: stupid fuel gauge
 

for sure check the tank/sender ground.may even want to add one for the cluster
i bought a spectra sender last year for the 79 no problems
and it sat 5 months over the winter,parked again now
