We sell lot of these Onan Prime switch kits and receive lot of positive
feedback.
Keep in mind the pump is LOW Pressure so there is less chance of flooding.
When they were new, all the items on fuel delivery system worked, so the
prime pump was not necessary.
Grace would push the prime pump and count to 10 then hit the starter switch
and fires up almost immediately.
