Keep in mind this ONLY works on the old 3 cylinder loop charged engines, and the older cross flow engines. The newer loopers WILL starve for fuel with this style pump as the new loopers don't have enough crankcase pressure differential to make them work at higher RPM's. I tried it on my 140, and made it almost on plane before it ran out of fuel. It would pump ALOT of fuel at idle, but open the throttle and it would stop pumping. I hooked up an electric fuel pump and ran the engien at different RPM's and you could watch it stop pumping at anything over 4000 or so.
Quite a few loopers have been burnt up by people trying to swap in the old style pumps to the loopers and starved em under load.
