2459412 发表于 2024-06-12 01:12:34 Depends how are the gaskets, orings? They get old and need to be replaced. How are the necks? The necks get worn and scratched and need to be filed flat with a file. How are the vents? are they plugged? How are the fuel lines especially above the trans? they get cracked and pull air or make the pump cavitate and air is put into tank. \nLots of reasons for your issues.Try a walmart bag under the cap and see if it stops.

","text":"They also have replacement caps called leak defender they coast a lot but money well spent","replyToPid":480838}
