2005 Grand Cherokee Hard to fill fuel tank

[ksucowboy84]

Looking for some guidance. We have a 2005 Grand Cherokee Laredo that builds up prssure in teh fuel system. When we pull up to fill it and remove the fuel cap, it releases a lot of pressure. It is hard to keep the fuel pump running because it keeps tripping off, while filling. I've replaced the fuel carbon canister, pulled the tank and blew air thru all the lines. I've also replace the evap purge valve. Any ideas would be appreciated. Thank you./

maybe try a try a new gas cap. I've had a few vehicles that you needed to pump gas in a little slower to avoid tripping.

2005 TJs do this when full. Pukes gas. Some have changed the fill tube and others found the vent tube bent/clogged.

Being you have lots of pressure it sounds like a vent is not working properly. Are you certain the pressure is positive not a vacuum?
