[Rhodes22-list] Dead Battery (Again)

Rummy,

While you're solving engine problems, have you ever dealt with a pulse fuel pump before?  My airplane tug (Kubota lawnmower with a Kawasaki 14 hp motor) quit running.  I replaced the fuel filter and discovered it isn't gravity feed and it doesn't have an electric fuel pump.  A little research on the net revealed a new critter I'd never heard of before - a pulse fuel pump.  It basically works like a heart, pressure on one side with a diaphragm that increases pressure on the other side.  I took it apart and the diaphragm looks fine.  It could be a lack of vacuum on the low pressure side due to intake valve clearances (their pretty close and this thing hasn't been touched in 15 years).  Anyway, never heard of this animal before today.  Have you got any experience with them?

Brad
