i have a 1998 summit 583, accidentally pulled the grommet for the main fuel line out of the fuel tank. whats the best way to push it back onto place, do i put a rod inside the tank to give me resistance? it seems the tank is flexible at the area, when i try to push the grommet it it just pushes in the tank. or should i use a small screwdriver and try and fold the corners into the hole a little bit at a time? thanks for your help.
