Ducato Fuel Gauge (1 Viewer)

[Johnnie Gee]

Hi, wonder if anyone else has found this problem.
On a long journey in my Hymer 584, (2.8 engine)I found that the fuel gauge suddenly dropped to nearly empty.
If I stop and start again it goes back up to the correct reading, I also noticed that(and this is the bizarre bit) if you sound the horn the fuel gauge goes back up to the correct reading again
I guess it must be a bad earth somewhere on the dash panel, as the horn may be a means of earthing the system????
Anybody had this problem, or better still how can I fix itoh:???

got exactly the same fault......

is your hymer built on the original ducato cab floor panel or hymer build from the bare chassis up?

ok....didnt know if they used the fiat cab floor or not.

the reason i asked is fiat have a plate in the left hand footwell to access the tank sender unit.

right....on my kontiki i removed the inspection plate above the tank and disconnected the tank sender plug, cleaned it as best i could (electronic contact cleaner spray) then replaced the plug.

seems to be ok 99.9% of the time.

i did notice, when it happened the first time, the tank was somewhere between 1/4 and empty according to mileage.

needle moved anywhere between full and empty but not a steady reading.

once i put more fuel in it behaved as it should but happened again as the fuel level dropped to around half full/empty.

as it worked ok when refilled i assume its the sender at fault but i can live with it when it does go wrong ( .1% of the time.)

Thanks Pappajohn,

I'll locate the plate and clean the sender connector when I get home(I'm rolling about on a boat on the North Sea just now)

Cheers
