Reply To: Fuel Pump Conversion Issue

[JACQUES]

drifter…

I did a pressure test 3-5 lbs psi on the pulse nipple of a B&S pump…well I did get loss of pressure upon release my pump indicating loss of air from the gold screen. plugging it with my finger holds pressure a bit longer but it does drop to 0 psi

This would probably explain your loss (leak) of fuel/oil being pushed out of the engine air nipple into the pump cavity

although I can not explain why you get so much juices from your crankcase….. the alternative is to try a different pump and see what happens. not being on site makes things a bit hard to evaluate.

let us know if you find a cure
