Faulty fuel gauge diagnosis

<< < (2/3) > >>

Neil Jones:
I lost my fuel gauge also, I took out the old gauge, dismantled the sender and discovered a mash of wires.  The new sender is great, although I don't like the rate at which its going down at the moment!

hobbit:
The temp on the series 2 1/4 engines if anything are very efficient, one of mine has no fan at all, and I only switch the fan in when running low speed, as soon as I get on open road over 40 the flaming thing cools right down, even when it was summer, in this weather it needs a rad cover to keep it warm, bit like me really :wink:

Miniman:
I had alot of problems with my fuel guage and it all came down to a bad Earth. Check its still connected and strong. Also if you have done this and its still the same sounds like all the wires in the fuel sender have perished and needs a new one. Take the sender out of the tank and do a risitance check on it then slowly move the fuel float see what happens if its all over the place then its the tiny coil of wires in the sender that are stuffed. If it gives a good reading clean all the way then we may need to think about another solution to your prob....

jimthelandyman:
I have the same problem with my fuel gauge but it flickers on and off when it gets below the half tank mark, its so annoying.

MisterC:
Thanks for all the replies and advice.  I put £20 quids worth of juice in today and the fuel gauge registered around half full!  On todays rate that's in the right ball park.  When I first noticed the problem it did appear to manifest itself once it got below half full, like jimthelandyman.  Bad earth seems a likely cause (thanks Miniman), where was your bad earth, as the route to earth appears to be the fuel sander unit itself via the fuel tank?  Thanks in advance.
