Gas cap hissing. Can’t barely pump gas.

When I replaced my canister, while the lines were still disconnected, I blew air into the tank from the filler neck to clean out the lines. I just used an air nozzle and a rag to seal the filler tube. Quite a bit of charcoal came out without having to drop the tank.

Good idea man. Did you do this on a near empty tank?

Mine does not do it but it did at one time, I replaced everything and is fixed. Not gonna mess around and piece by piece it. I have gotten in to the habit with all my vehicles and anyone else's I may be putting gas in, and I never stick the nozzle all the way in and I never pump it on the fastest step/click.
