Hey everyone - I've seen a lot of similar threads but not this exact one so I am hoping someone can help?
I took out the factory instrument cluster on my 88' 4.2L since they weren't working right. Hooked up the new autometer fuel gauge (it is the correct one for the Jeep) and the gauge barely moved up.
1) Is the ground on the gauge supposed to go directly to the fuel sending unit? Now, it's grounded to the same place as the bulb lights and new clock. I am planning on running the 18 gauge, two conductor wire back to the sending unit, then hooking into the brown wire that powered the factory gauge. Am I on the right track?
2) Does anyone have a write up on replacing the fuel sending unit, or any advise? Does the tank need to be completely removed? Where's the best place to get one -- and is there anything else that should be replaced while doing the procedure? Thanks!
