Hi Everyone - I have a 1968 Series 2a 109 2.25 petrol and recently noticed the engine oil has a strong gasoline smell when checking the dipstick.

There is an electric fuel pump running inline with the original mechanical fuel pump on the block.

- Is it likely that the diaphragm on the mechanical fuel pump ruptured into the block? Any other source to be leaking fuel into the oil?

- Can i bypass the mechanical fuel pump and just run the electric pump to the carburetor?

I have been debating switching back to a mechanical fuel pump. I appreciate your thoughts.

Thanks for the help! Ben
