Is there any way to test the fuel level sending unit before I put it back in the tank. It has alot of rust film on it and sounds like some rust flakes got in it. I have a cleaner looker unit out of a parts car but want to make sure it works.
Thanks |

Not another one! Group: Benefactors Posts: 4,526 Joined: 1-March 04 From: San Mateo, CA Member No.: 1,743  |
One of the terminals is the sender, the other is for the low fuel light. Ground is the lid of the unit. Between ground and the light terminal, you should get 0-5 ohms with the float at the bottom, and infinite resistance with the float off the bottom. That's the light terminal. The other terminal and ground should show 0-10 ohms when the float is at the top (full), and 75-100 ohms when the float is at the bottom (empty).
