ok i was just sittin in the smiths parkin lot waitin on someone jammin to music and i hear a chime i look at my dash and my fuel gauge went from a little under half a tank to well below a quarter and the fuel light was on so i shut it off jumped out to check for a puddle nothin jumped back in just turned the key on and it was back under half a tank turned key off and when i started it back up it was at a quarter again i just rolled with it and it came back up any way sorry this is two hours long and probably nothin to lose sleep over but anyone else had this happen all comments welcome thanks in advance.

 

hmmm weird must be a loose wire or a bad level sensor

The connector to the fuel sender is accessible with the box on, but can be tricky to remove. If you can remove it, check the contacts for debris. If you have a multi meter and are handy using it, check continuity between the sender and junction block under the front, left cab support. If all the wiring is good, it is probably the sender itself. My buddy had a level sender problem in his '00. The tank would be empty when the gauge read higher, and everyday it got worse. He finally changed it when 1/2 tank was actually empty.

 

alright i got to replace the pickup box any way i was already goin to add a drawstraw while im doin that ill check all that thanks for the help

 

When mine started doing this on the '02 it was time to replace the sender as that was the issue. $70 from the dealer at the time. You might want to consider just getting the complete canister assembly with the draw straw included from Vulcan if you are going to go that route. Probably save yourself some headache...

 

is it best to raise the bed to change the fuel sending unit on a 2001 dodge 2500 with 5.9 Cummings engine

 

in my opinion yes pulling the box off is way easier than dropping the tank i dropped the tank installing my fass but i aint never going to do that again theres only 4 bolt holding the box on pull them then just lift the box off i used a tractor pulling my box off but thats cause i was a one man crew and had a tractor easily available there really light two people could lift one off easy
by the way

 

thanks a lot PUREBRED REDNECK
