Recently my 03 fuel tank hasstarted not venting. I do have custom paint but it's been installed since January. About the last 1500 miles the tank is not venting pressure. When I fill up the tank has a vacum type hiss when the cap is opened and now if it sits in the sun the same things happens but it's pressurized from the heat. Has anybody else had their vent stop venting and what couldbe the cause of this sudden blockage?

Im doing a service next week so I'll pull the tank to clean the filter, replace the plugs and I'll check the vent and lines then.
