With the ignition on the needle on the gauge lifts to E but goes no further despite the tank being full.
I pulled the sender, wired up a new ground and hooked up a new wire from the gauge to the sender and tested the sender manually by turning it upside down and then back. The needle goes from empty to full and back to empty. Just to double check I test the resistance, 0.2 ohms right side up, 89.9 ohms upside down (the range is 0-90 ohms). So I put the sender back in the tank with the new wiring, switch on the ignition and... the needle rises to E and goes no further. So I think maybe, somehow, the floats not lifting. So I pull the sender, fill a bucket of water, dip it in, and the needle on the gauge rises and tells me I have half a tank - or less or more depending how much I submerge it. In other words, the damn thing is working. So I put it back in the tank and nothing, the gauge rises to E and stays!!! What the hell am I missing here? It works in a bucket of water but move it a foot and put it in my gas tank and nothing. John |

Yah, something isn't right with that sender. If it wasn't so new and possibly under warranty, I would say take it apart. Get on the phone with them, maybe they will take all of it back.
Why are you using an aftermarket sender and gas gauge? Does your old combo gauge not work? |

Why are you using an aftermarket sender and gas gauge? Does your old combo gauge not work? It's a 6 conversion with a 2.7RS. The guy that built it swapped out the gas gauge for a 911 oil temp/oil pressure gauge. The sender and gauge aren't new, the set up just wasn't working when I bought the car. So I could take it apart, I'd just need to find a plate to cover the hole in the tank... And probably increase my skill level... I'll give the guy a call Monday and if my only option is to replace them I'll consider taking them apart. |
