hi.. i just recently noticed about a week now that i cannot add gas to my 1995 gmc yukon. dont know what is wrong but i do know that the fuel guage doesnt work.. any advice
truck seems to be low in gas but i cannot add gas to tank because it comes right back out. i drive less than 50 miles per week and btw this truck has over 300,00 miles but is all i have
Must be some blockage in the gas filler line,
Hi ya TST. Could be that, a blockage in the filler or the EVAP system is kicking it back out. If the evap line to charcoal canister gets clogged ..same thing will happen. Or even the vacuum switch to the canister is stuck closed, not allowing the air and fumes out. Hence, no gas will go in
