Reply To: Fuel Pump Conversion Issue

[JACQUES]

the 5.5 I sold to a neigbour with the modified channel trolls all day long yet…he does mention that the plugs foul up faster than he likes.

Obviously the unburnt fuel oil mix which should,,…just drain out the purge valve are causing an overly rich mixture but the pump works fine

yours seems to be pushing juices it out the “reassigned” pulse nipple normally these juices would end up back in the pressurized tank via the air line.

I am still suspicious that your crankcase drain valve and/ or internal crankcase drain orifices may not be doing a good a job as they should ending up as excess juices in your pulse line

pressure pulse wise I don’t think a fuel pump would care if it was being pumped with… liquids or just air but your B&S pumps don’t seem to like it . I can see the gold screen as an atmospheric balance feature to let the diaphragm flex both ways but why fuel actually leaks across the diaphragm and reach the screen is odd to say the least . could be crappy diaphragms being destroyed by the fuel ….

if you plan to junk the B&S may as well open one up and look-see inside..for us!
