Weird trivia question & shot in the dark.


Does anyone know what the Stock or Stock replacement Fuel Sending Unit (can I call it that?) ohm range reading should be in a late 60's dodge?

i.e. how many ohms should empty be and how many should full be?

Thanks!

Actually, that one is beyond me right now. You will need to track down a parts book ar a true Dodge part guru.

In the meantime, these links might help:

Oh cool links. Thanks Reed.


It would appear the approximate Stock range for the Mopar OE non linear fuel senders would be around 73Ωs Empty / 8-12Ωs Full

Means I got the wrong Gauge. BAHHHH!. ;-)



This one should work better: Autometer Fuel Product #:3315



Thanks guys!

I forgot I bought the A100 service manual. Had some useful info on how the cluster works.
