Every time i turn the truck on it reads full, 95% sire its not full, the longer i drive the farther down it goes, but i still have no clue how much fuel i have, any ideas?
sounds like the fuel sending unit? someone correct me if I'm wrong but I had this problem a long time ago on my e99. Would read full most of the time and before I realized it was malfunctioning I ran out of fuel twice. Didn't wanna screw with it so I just started setting the trip odometer every fill up and went by that. Gauge started working normally again though about a year later.
