Fuel pump

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have a simplicity sunstar with a kohler ch20.  The vacuum fuel pump would not work because there was too much crankcase pressure. I did not have the time to rebuild it so I bought the mechanical valve cover pump. 
It has been two years now since I put it on and I rebuilt the engine last year. 
My question is how long does the mechanical pump work before it is worn out and do any of the pieces of it break off and get into the valve springs, lifters and push rods.
