92' Ford Ranger with 2.9 V6. My truck failed emissions inspection last month in the fuel system pressure category. I installed a new fuel tank filler neck today because the old one had cracks in the rubber.
I had it re-inspected yesterday and it failed again for the same reason. Today, I'm going to replace the vapor hose that trails from the gas tank to the charcoal canister in the engine bay. The guys at the emissions station said they smelled gasoline vapor under the left side of the truck, where the fuel/vapor lines are
Last year, I replaced the charcoal canister and fuel pump. My fuel vapor system has no electronic function.
There is something else that concerns me. When I replaced the fuel pump last year, I was unable to secure one fuel pump locking ring tab under one of the notches on top of the gas tank. When I put my nose close to the fuel pump mounting point, there is a slight smell of gas fumes.
There is a rubber seal under the locking ring. And the locking ring seems tight. But could this be one of the causes of escaping gas fumes? I had great difficulty trying to slide that last locking ring tab under the notch. I finally gave up when I was installing it last year.
