Having just bought my son a 110 to match mine, (better nic than mine!) there are a few gremlins to sort out. One of these is the fuel guage reading just over quarter full although has had £85 worth of Diesel put in. Have done a search but not found the answer I need. I do seem to recall this may be a sympton of the wrong fuel pump, or to be more precise, the wrong sender unit being fitted. Ie a defender 90 fuel pump/sender unit rather than the 110 unit. Ring any bells anybody?

It could be. The other alternative is that the sender was damaged or bent when the pump was fitted.

When I fitted my new pump the seal didn't locate fully so it had a leak. I removed the pump and re-fitted the seal. I must of caught the sender when putting the pump back in as it now drops like a stone and I'm down to 1/4 tank when I actually have 2/3's. As I'm planning on fitting an under arch tank in the near future I haven't done anything about it as it will be pretty accurate then.

Mine does exactly the same Ratty. I've had that pump in and out too many times to try and sort it. Tried adjusting the arm etc but given up now as nothing obviously bent and gauge works just fine with the pump out of the tank. ??????

more likely catching in the tube part sender pump sits in on bottom of tank

are you saying that the arm needs lifting up and clear as the pump is put in?

Looks like I will have to cut out a hatch in this one as I had to do in my own one to get access to the pump without dropping the tank. Something else for the ever lengthening todo list!
