Title: Fulvia series 1 fuel sender problems Post by: zagatoman on 02 May, 2010, 01:51:27 PM Is anyone able to help me on fixing my fuel gauge or sender unit on my series 1 Fulvia?
After having completed renovating my Fulvia the only thing I cant get sorted is the fuel gauge. I have two wires that go from the fuel gage on the dashboard then to the sender, I have no movement on the clock although I have plenty of fuel in the tank. I have earthed each wire at the tank end, one eliminates the warning light the other moves the fuel clock to show full so I presume the clock is fine. How do I test a fuel sender unit on a Lancia Fulvia series 1? Is the sender the same on all series Fulvias? Do I have to earth the tank? Am I right in thinking the gauge is fine?

I've got loads of photos of it if you need. Title: Re: Fulvia series 1 fuel sender problems Post by: zagatoman on 02 May, 2010, 02:14:02 PM Hi Neil
Will be taking out tomorrow. If it all looks fine and moves but still will not register on the gauge is the sender at fault or do I have to do something else? Should I run an earth from the tank?

I took it to bits, cleaned and de-scaled it then re-assembled it. The other thing is to check that the float doesn't have a hole in it.
The circuit should be earthed via the fixings and the tank. Check it with a multimeter. Title: Re: Fulvia series 1 fuel sender problems Post by: zagatoman on 03 May, 2010, 11:31:15 AM Hi Neil, all sorted now.
You were right about giving it a good clean, now works perfectly. Thanks for your advice. Paul |
