Fueling up

Asked by Apr 12, 2017 at 09:32 PM about the 1988 Chevrolet C/K 2500 Scottsdale Standard Cab LB

Question type: General

Trying to fuel up and the nozzle from the pump
only fills the neck of the tank and kicks it off. Tried
pulling the nozzle out and still does same thing
only fills neck up. Ran a siphon hose down the
neck and it went all the way into the tank. Doesn't
seem to have a blockage in it. Any suggestions?

Sounds like the EVAP system is plugged up, may be the canister, or a line. There is no where for the air to escape when putting gas into the tank.

THATS RIGHT ..NO VENTING..YOU CAN REMOVE THE LITTLE EVAP CANISTER AND SHAKEIT UP..LOTS OF TIMES IT WILL ALLOW BETTER VENTING.OR IF YOUR HANDY YOU CAN OPEN IT UP AND CLEA IT UP.. .. OR GET ONE FROM THE JUNK YARD..OR BUY ONE....THE BEST PRICE I HAVE FOUND WAS $47.00 ..A RIP OFF EVEN AT THAT PRICE.. .THEN PUT IT BACK IN

Took the charcoal canister out tryied blowing it out. It exploded all over my shop. Don't do like the u tube video says! You'll be cleaning charcoal out of everything!

Have also blew air through the line back to the tank. It's all clear only thing I haven't done is take the fill tube and auxiliary hose of the truck and check for blockages.
