fuel gauge issues - Benzworld.org

I have a very minor issue with the fuel level gauge.

When I fill the tank, the gauge reads full as it should. However, after driving as little as 15 miles, the needle reads 7/8ths full.

The last quarter tank seems to be about 6 gallons though, indicating that its a touch off.

Is there any way to fiddle with the sender to fix this?

when I get to the tank, what should I be looking to do?

thanks

I also have a fuel gage problem.Mine is when I fill up it only goes to the last line but not all the way up. The tank is full but the gage doesn't indicate as full.

I think both of you have a sending unit problem but I don't remember reading about any fixes on here; typically, I think people just replace them. Hopefully someone will know of a way to fix or tweak them back to accuracy. Good Luck!

^^1+...yes it sounds like you need to replace your fuel sending unit.

well, since mine still is accurate when it gets low (or at least reads conservative), I won't bother with it.

Can't it be just the gage that isn't precise or stuck.
I think I had read somewhere that someone had adjusted how the needle in his gage goes up.So it would be at the full level instead of being at the lower line.

Good point here I think Oliver. I ran out of gas once in my life and that was enough. If it's accurate enough to prevent that, so be it.

I guess it's possible that the needle sticks, needs to be re-calibrated, or is dragging along the clear covering because it became mis-aligned. This might be worthy of a search, but I only remember the "replace the sending unit" fix already mentioned.

Have never seen reliable fuel gauge in my life. I always set daily meter at fill up and drive by it. When I get new (for me) vehicle I usually take a full fuel can with me and drive on reserve. Diesels don't like to be run dry, but I ran on reserve light for 60 miles and when I need it, I know I am safe on reserve for at least 50.
