Mystery fuel

[greenie]

I drove to the lake and back home when I noticed I used 1/2 a tank of fuel.The next day I had a full tank. Is there a diesel goddes,filling
SD's at night.
Or is someone steeling fuel?
Dumping water in the tank?
Guage broke?

I think I'll start with checking the fuel,at the bowel.I don't know who does a fuel analysis. Any suggestions??

I thought ya'll d like this one.

It is the fluctuation in the gauge. It goes down really fast but takes forever to come back up. Used to happen to me in my OBS F150 a lot.

I check it this morning and the gauge was reading alright.Later on I saw the gauge was off. Is it the gauge or the sending unit in the tank ,ya think.

It is just the fluctuation of thr fuel sloshing around as you drive. It is the float in the tank going up and down as the fuel moves around. For some reason those gauges REALLY reacted to fuel movement

the gauge will move really slow. if you park on a slope your gauge will be inaccurate for a short time. If you ever fill up your tank with your truck on you will notice that your gauge goes up EXTREMELY slow. once you turn the truck off and back on after filling up your gauge should shoot to full.

Mine can go from full to 1/2 just by going down hill for a minute and stay like that for a good 15 minutes.
