Hello all,
Fuel has been entering into my oil on my Cockshutt 1650D. It has been mentioned to start with the fuel lift pump as they are known to fail. I have the pump off and disassembled. I can't see any tears in the upper or lower diaphragm. When they let fuel past where do they fail? Lower diaphragm seems to be the critical last stop before getting to the block but can't see any obvious damage.
