Not sure where to put this really. But I bought an aftermarket bezel and gauges for my 51 Cambridge. the supplied fuel level gauge is a 240-33 ohm setup. Most older mopars use 73-10. Well in 1951 Mopar was 90-10, probably more years than that. Both use 10 ohms for full but differ on the reading for empty which means it won't read empty correctly. I suppose that isn't a bad thing as it will show empty early which is better than showing a quarter tank and actually being empty. there is no gauge matching the rest I am running that uses the stock sending unit spread though.



Speedway sells an interface module that makes any sender work with any gauge, though at $105 it's cheaper to buy the right gauge if available.

Might just spring for the 73-10 gauge.
