needing a pulse fuel pump, thoughts?

[deejaaa]

OldMiniBikes has 3 to choose from. this is going on the GX390. lift is no more than 3 inches. tank outlet is lower than it should and moving the tank is not an option. i could build another tank but want to ride. not sure if these will pump enough for a 390 or not. any thoughts on these?

I bought the Walbro one from OldMiniBikes for my 390.

Dunno yet if it will work, not that far in my build yet....

These little pumps work surprising well. Get one that has replacement diaphrams available. I have used them on several motors. One needed a 8 inch lift for a dunegote. I tapped a hose barb into the intake manifold for the pulse. You could also use a crankcase vent for a pulse.

did you research it to see if it will be enough for the 390? i was going to use the valve cover for my pulse.

looks like the Kawasaki isn't serviceable so i will go with the Walbro.
might as well get a sprocket from OldMiniBikes while i place the order.

did some reading.
Walbro unit is serviceable, good to 25 hp, 4-stroke pulse is better from intake, flow/lift/pressure dependent on application.
i will still get pulse from vc because i have all the fittings/tubing i need.
