Reply To: Fuel pump replacement advice Evinrude 4006E

There are various ways to approach this, including buying some bulk diaphragm material and making your own, and cobbling up a lawnmower pump–cost about $5-10.

But I note there are clone pumps on Amazon for $16 and change. https://www.amazon.com/OMC-Johnson-Evinrude-BRP-Assembly/dp/B07D8Y74RW This might be the most painless way to go.

OMC at one time did, I think, list parts for these small pumps, and someone can probably post a breakdown. My recollection is that they are somewhat fussy and fiddly to assemble, but far from impossible. If it really isn’t pumping, you likely have nothing to lose by taking it apart–being careful to retain little springs, etc. The diaphragm may be hard, or ripped. 1970 was before the days of alcohol-containing fuels and organic materials used then didn’t necessarily stand up well to ethanol content….
