Gas Gauge Adjustment

My LT never indicates full on the fuel gauge. I am considering the addition of a small resistor across the wires on the sending unit connection to solve this. Has anyone tried this before with any success? Thanks for any input.

Re: Gas Gauge Adjustment

Dean,

Your sending unit may have been crushed. The tube in the gas tank will bend when you get a vacum in your tank. Have you ever noticed the rushing air sound when you remove the gas cap or had it hard to unscrew? I had this happen and discovered it going across the desert. My gas tank wouldn't show full, but more important it didn't show just how empty I really was either.

Re: Gas Gauge Adjustment

As mentioned in other threads, it may not just be from the tank collapse. It could also be dented from a gas nozzle. One way or the other it sounds like you'll be pulling it out. The dents are easy enough to push out. You just need to find something with the same I.D. as the sending tube.
If you find it's not dented, I've heard that the dealer can recalibrate, but that might just be for the 1 gallon to empty setting.

Good luck,
Jer

Re: Gas Gauge Adjustment

The tube can also get "Dinged" by the fuel nozzle during fill up causing the sending unit to not go all the way up inside the tube. Don't put the nozzle in to far.

Re: Gas Gauge Adjustment

I've pulled the sending unit and it's fine. The gauge just needs to be tweaked about 1/10 of a tank to read completely full. I'm pretty sure adding some ohms across the connection would do the trick and just wondered if anyone else had adjusted their gauge this way. There's probably an adjustment screw on the gauge itself but getting to the sending unit is only a 10 minute job versus pulling the gauge assembly.

Re: Gas Gauge Adjustment

I have just the opposite issue with my Lincoln, the guage reads above full untill I have driven 100 miles. I am more worried about the other end of the guage because when I fill the LT up I KNOW it is full.

Re: Gas Gauge Adjustment

If you fill the tank with the bike on the centerstand ou will never get a full tank. Try filling up on the sidestand, if you haven't already.
