faulty petrol gauge

[beesbal]

hi guys.my petrol guage seems to be faulty,filled up the tank,the guage only showed half,then later in the day it showed full,now it has a mind of its own.Any suggestion as to what may be the cause

If you have a elec. sender, the coils in the sender unit have started comming apart and it's catching. You are looking at a new sender and they are pretty expensive.

Mine also does that...I don't trust it anymore... Thanks for the advice. Prob: Must lift bonnet on Beamish buggy to get to sender unit. Sod that. Buy little jerrycan...

hey my petrol gauge does the same! its like an erratic bunny. from what i can see on mine it seems as though the metal contacts where all the wires under the bonet go into the dash are connected are rusted. so i took them off and scraped and cleaned the pieces a little and then it worked like new for awhile. The connecters to the bulbs that light up my dash were also rusted and a simple clean made the bulb work again aswell.

Sorted out my petrol gauge,got a replacement sender unit and a little control box that fits behind the dash,all for under 100 bucks(second hand corse)
