OK guys, I need help. My MF35 hates me, or least the new gas. At least twice a year my Sediment bowl gasket starts leaking. What would anyone suggest for gasket material. Cork seems to work best but what would resolve this issue permanently, I am afraid to empty the sediment bowl for fear I cannot stop it from leaking. I have bought at least 4 new complete bowl assemblies in the last two years trying to I fix the issue but none have given me more that 6 months peace. Finally got tired of the same issue on an MF50 so took and replumbed the whole thing with a shut off valve and auto fuel filter. Help...?.
