So my jeep sat on stands for about 6 months for some upgrades. Before that happened I could put the pump nozzle in, pull the trigger and the gas would go into the tank as fast as it would pump. Fast forward to present day apocalypse, I can barely get gas into the tank with out the nozzle kicking off. This is extremely frustrating as it takes about 10 mins or so to fill up the Jeep. When the jeep was out of commission, I never messed with the fueling system. Only suspension and drive train upgrades. Any ideas on what could be causing this? Help a dumb redneck out!
