Just wondering if any old run-of-the-mill electronic fuel guage will work with LPG.
My point of interest is whether or not the signal from the guage at the tank is the same as an ordinary fuel sender unit.

Thanks heaps.
Paul.

usually you can use the std gauge. just need to check the resistance values coming out of the gas senderr and compare with resistance coming from petrol sender. If the resistances are the same you should be able to easily adapt a manual change over switch to select either gas or petrol. If the resistances are different you may be able to change the gas sender resistance to match the petrol and still setup a change over switch.
I dont think I've got hold of it, so I hope this helps.

I understand all the electronic wiring as such but how would I check the resistances of the sender signals?
Thanks for the reply.
