Evinrude 70 fuel pump
Back to the ancient Evinrude 70. I had a burst of enthusiasm yesterday and so stripped the carbs and fuel pump. All were clean as you like, but a few of the fuel pipes a bit lose on the in side, so I put proper clips on instead of cable ties. It worked a bit better, but would still accellerate and then run out of beans, but pumping the priming bulb enthusiastically would make it run steadily. That sounds definitely like a fuel pump.
The guts of the pump looked OK, except for a pin-hole in the casting on the crankcase side. The pin hole has probably been there for ever and probably makes no difference...
I could either refurbish the pump, at about £30 parts, buy a new pump at about £70, or bin it and buy an electric pump for between £10 and £30. I am pretty tempted by the electric option as I get a new guaranteed pump that is easy to test. Do you think replacing the pump with an electric one is daft? There are plenty of electric pumps that are desiged for use with carbs and run at about 4psi.
All the best
