MQ Petrol Guage.
Hey, they are still floating around. Still got mine.
This question should relate to any vehicle so hopefully anyone can help me on this one.
the fuel guage is playing up.
it may as well not be working but now when the tanks full it shows on full on the guage but when its empty it only shows 3/4 full on the guage.
Nightmare to judge how much fuel you got left when travelling long distances.
Has anbody had this prob, can you fix it yourself or is it more techincal than that?
Cheers guys, any help would be great!
It's like the reader has possibly moved and not reading the fuel level properly. Havent done anything yet, i found this site and thought someone might have experienced it b4.
Thanks!

It definitely sounds like the fuel sender is having issues. At first, I always think "electrical" but being an MQ I'm tipping that there isn't a hell of a lot of electrical stuff on it! I could be wrong..
I don't know too much about fuel sender/floats, but I picture it a bit like the float in your toilet sistern.

Hope that helps a bit.

when its low on fuel gently tap the sender with a plastic tipped hammer it may well just be stuck.
Just a thought
Cheers

you must remember meakinelli, that yours is not ancient, but is an old truck, so things like wiring gremlins will possibly be there.
time and patience can fix anything - with a little knowledge on what your doing helps (are you mechanically minded, or electrically minded?)
when yours plays up, is it sticking, or going erratically all over the place?
I am guessing that Locks got his fixed, as there is no new replies from him about this

Hi, yes I realised the amount of problems it may produce when I bought it. It sat at zero for a while but then shot up. Hasn’t done it since the snow melted. I am actually a helicopter technician flying with the air ambulance. Sounds silly but they are miles apart. All black boxes and self diagnosing equipment. No rust, oil leaks or taping with hammers required. Half the reason I bought the bugger was to have fun playing with it and restoring the bits that go wrong.

it probably sat at zero, as it had been sitting for awhile, the fuel (petrol or diesel) has a small amount of varnish like substance in it. with it sitting for awhile, the varnish has dried out, and stuck the needle on the rheostat (think of a pencil, with copper wires wrapped around it tightly, then a needle passes along the edge, giving the reading to the dash gauge)
the major problem with ALL fuel gauges, is the previous user......
best way is to fill, and then use till nearly empty, then re-fill
most people fill, then use till about 1/2 full, then re-fill
thats why sometimes you think it has used the first 1/2 of the tank quickly, and the 2nd 1/2 slowly

I put myself out from these situations by getting along my fuel carrying essential with me, I never go out without my Desert Fox Fuel Bladder on Long Trips. This has been my companion for a long time. I recommend you to stop getting nightmares to judge how much fuel you got left, just buy one and enjoy your long trips.
