The fuel tank on my new-to-me boat must have been replaced sometime in the past. There is no gauge fitted to the tank but there is a fuel gauge on the instrument panel and a pair of wires adjacent to the tank.
Easy, I thought - measure the resistance required for empty and full, then buy a standard sender unit.
However, Empty equates to 80ohms and full requires a near short; 22ohms equates to the 3/4 mark. This range does not appear to be standard?
A google search on ybw.com didn't reveal any useful information, but a general search turned up some shallow (for cars) senders that were 0 to 73ohms. [I need a 75cm sensor]
Before I chase any more wild geese, can anyone throw any light on the subject (The boat is a Moody c.1990)
Regards & Thanks in advance
