Ok – I must have been brain dead when I wrote that last post – Of course the fuel pump does not work from the exhaust port – but when I took the pump apart, it looked like soot inside the pump on that side of the diaphragm, but I think it was just fine powdered black stuff that came off the diaphragm over time.
Upon further examination, all the pump parts look fine,but I put a finger on one side of the filter and tried to blow through it and it was difficult, so I think I found my fuel-starvation after 5 seconds at WOT problem. I will try it on the lake tomorrow with no filter, as I don’t have another one here. I’ll order a filter.
Frank – thanks for the info about the 18-7351 pump – I’ll order one if I still have fuel starvation problems. I’ve already swapped tanks and gaslines with ones that work fine on a 40 HP on another boat.
Thx,
Dave
