does this engine have a vacuum type fuel pump ? Would a split vacuum hose from the valve cover to the fuel pump cause it not to run?
 
Some Briggs engines use a fuel-pump ... it depends on whether the gas-tank is a gravity feed or not
yes if the "PULSE-HOSE" from the valve cover to the pump is damaged ...you need to replace it ... it is
not really a vacuum hose per say .. I hope this is what we are conversing about .. ( click on image )

.MAGIC .... ( LOL )

actually the movement of the piston in the cylinder (with the valve cover with hose) moves a diaphragm inside
the pump back and forth pulling from the tank and pushing to the carb.
