Lately I've noticed it takes a few more gallons of fuel to fill my tank than
usual. I normally only need about 26 gallons to fill up when the gauge is at
about 1/8th of a tank. The last few fills required 30 gallons or more. I
didn't think too much of it until yesterday. I ran out of fuel on the
highway pulling a trailer with just under 1/8th of a tank. Luckily, I was
close enough to home to call my wife and have her rescue me with a can of
diesel and my tool box. What a pain in the a.s to get started again after
you run a diesel dry. It takes much longer to bleed the air out of the
system than it does after a fuel filter change. I ran out only three miles
from where I planed to stop for fuel. After adding almost all of a 5 gallon
can of fuel to the tank (some was dumped into the mostly empty filter
canister, some dumped on myself) it took 29.7 gallons to finish filling up.
I have a 34 gallon tank on my '99 2500 QC SB so now I'm convinced the gauge
is reading too high. Anyone have any ideas why the fuel gauge is reading
higher than it should? Does the sending unit have resistance values that I
can verify with a meter?
