When I was filling the tank about a month ago, I must have overfilled it. Heard a big pop. I think the tank expanded and the fuel sender began leaking. When I pulled out the screws they felt wrong (cross threaded?). Sure enough three of the five new screws dont fit well into the exisitng screw holes. Tried other screws but none worked. I could screw them in half way but then felt the resistance. I think the 3 screw holes got ruined (streched) when the tank popped. Im keeping the tank filled about 3/4 an the new sender is not leaking, but I need to address this. Any suggesstions appreciated.
