i take it that you dont have one to measure? do you have the fuel gauge? do you have a decade box? if so then you can hook up the decade box to the fuel gauge and try out ohms values till you get full and empty readings on the gauge. these are then the ohms values for the sender.

see.... air and water do mix 😉

I bought a replacement for VW # 113-919-049-D, which fits Beetles from '68 - '77 & Ghia from '74 on. It is a Flotamex brand, #BAA-919-051.
Resistance range for this sender is: Full (float up) = 2 ohms, empty (float down) = 73 ohms. When I installed it the float must have been resting on the bottom as it read 60 ohms empty, so I took it out and bent the float arm up a bit until it read 73 Ohm empty.

For anyone doing an engine conversion, this sender is fairly compatible with the fuel gauge in a Mazda RX-7 series 6 instrument cluster, which wants 7 ohm full & 76 ohm empty.
