Hey guys i have a 702 k161s 7hp it has the vacuum fuel pump that bolts to the case where a mechanical pump goes and i wanted to know if i could put a mechanical in place of it?  Do all the camshafts have a lobe for the pump? 

 

where do you suggest i get one from i think the new ones are plastic.

Mechanical one is no better than a vacuum one when working properly. Any reason for wanting the mechanical over the vacuum?

You will have to get the spec number off your engine and find the part number for the camshaft. Cross-reference that number and see if it is the same as a camshaft from an engine that uses a mechanical pump.

or pull eh pump and crank the engine  you will see a cam action if there is one  Hold your finger on it and turn the engine by hand (Spark plug out!!!)

i just think i would trust mechanical more than vacuum and think just more reliable 

 

i just looked up the camshaft and shows the same with mechanical
