Hi all,
Just picked up a 1998 discovery,

was at the gas station and I was not able to add gas.

It was almost on empty, light was on, but when I was filling up, the
pump will stop like it was full and I was topping off. air was coming
out of the fill hole, I had to add about 1/4 to 1/3 gallon, stop and
try again, was able to get 3 gallons in before I gave up, enough to
continue my trip

any ideas???

many thanks

 

Sounds like one of the vent lines is not allowing the tank to breathe. You are going to need to have some check all the fuel filler lines and vent to find the cause.
By chance you might also want to try another fuel pump, some gas stations have warn out filler handles and they just shut off early.

I tried 2 different pumps, and someone got to the first pump Iwas using, and he had no trouble

I am going to see if Ican check the vent lines

thanks

 

might want to check to see if the fuel gauge is faulty and reading empty instead of full?? just a thought
