Fuel tank sender repair

Fuel gauge hasn't worked since I purchased the car and the re-wire is an opportunity to fix. Fuel sender is located in the top of the fuel tank and fixed with 6 allen head screws. Fuel sender is lower than the top of the tank so expect a flood of fuel if the fuel level is above this. 


The float on the sender was stuck but freed up easily enough by moving it about. The resistance reading were very erratic. Taking off the cover and cleaning with a contact cleaner got it working and apart from a new gasket being needed this was an easy fix.

 



Neighbour has 3d printed a TPU gasket which is resistant to fuel. 

Resistance tank full = 90 ohms
Resistance tank empty = 5 ohms

It is important to connect a 0v wire to the sender body ensuring it is at the same potential as the gauge 0v.

Dashboard


Some success cleaning the dashboard with Bilt Hamber Surfex-HD. Sprayed on at 50% and watched the years of brown tobacco and other gunge come away. Overall quite faded compared to the reverse.
