Jerry77 1,218 #2 Posted July 7, 2017 (edited) Don't see why not...I would seal off the inlet/outlet on the original pump - be sure to add an inline fuse for the electric pump - output pressure of the pump should be less than 3psi to prevent blowing out the seat on your carb...some use a relay off the accessories tab on your key switch to activate the pump - I wired mine direct to the key switch accessories tab - pump doesn't draw much current..I did add a switch for the pump so I could have the key on for maintenance without having the pump running at the same time..Be sure to locate the pump as low as possible on the tractor - electrics push better than they pull...
