Hi all. Today I filled up the petrol tank with about £25 worth of super unleaded, not just to have a load in there in order to start and run the engine every now and then but mainly to see if the needle will move on the gauge. Unfortunately it didn't even flinch.
The gauge is brand new, albeit 10 years old unused.
The wiring hasn't been touched since it worked last time.
The sender is the original one. I've never touched it.
My bet would be that the sender isn't working. I don't know anything about petrol tank senders having never replaced one. Can they easily go wrong after being laid up for 15 years? Can they get stuck? Can they be repaired or is it better to get a new one? etc...
Could someone please help me with a series of instructions, in process of elimination order, for me to work out what the problem is? For example, first how to test the wiring. If it comes down to being the sender, how I best remove it. I'm pretty sure that it won't come out very easily as the rear bulkhead overhang is in the way but if it can be taken out at an angle then maybe it's possible. Here's a photo. Thanks for any help about this.
The fiberglass you can see above the tank overhangs the sender almost exactly.
