fuel pump leaked into oil

[brucepinpoint]

My fuel pump leaked fuel into the oil on the sea water pump. Have to replace fuel pump. What is the difference between Mercruiser and Sierra and Airtex. The prices vary greatly

Only difference is price. mercruiser buys from someone and marks it up.

Forget the mechanical abomination and use the electric fuel pump for a carb application ans oil pressure switch.
I install a cube relay to power the electric pump. protects the pressure switch from high fuel pump current
