...still getting hit and miss readings...
087-2246059
I've the same problem in my 77 bay. It used to be better but has got worse recently. I just make sure and fill every 180K now. And always keep a can of petrol in the vanwhen its full, it reads full but when it gets to about 3/4 full ..... it falls to empty!
It is possible that the gauge is the fault, but unlikely. Test the sender with a mutimeter on the resistance setting, as you raise the float in a steady and slow movement, the reading should change on the meter in the same steady movement, if not this is the fault, usually a gauge either works or doesn't there is really no inbetween apart from a smooth but inacurate reading eg. too high or too low. Also earth the gauge wire at the sender end and gauge should go up full, and wriggle all wiring to check for a broken wire or bad connection.i fiited a new loom and fitted a new guage when i manually move the float to full the guage readfs full but as i lower it the reading fall and at half way it vanishes off the guage.
so my conclusion is the guage as all else is new
