briggs fuel pump leaks oil

tractorguy2 · Aug 12, 2014

I trouble with an 18hp Briggs with a vacuum fuel
pump.The Vacuum line connect to the dip stick
tube. The pump seems to be sucking oil and is
leaking oil out the vent hole.

I replaced the pump. It worked for about three
days and is leaking oil out the vent again.

It is not over full and I don't think gas is
getting in the crank case.

Any ideas??

You may have a plugged vent tube going to the air breather box, letting the engine build up too much pressure. How much pressure do you feel when you remove the dipstick with the engine running?

Might take the crankcase breather tube and filter out and check for restriction. Building crankcase pressure?
