1968 Johnson FD-22M Cant find replacement fuel pump

[sparkplug619]

Hello. I recently purchased my first boat, cool little aluminum thing equipped with a 1968 Johnson 20HP FD-22M. The thing sat for quite some time so im doing all the necessaries to get it ready for the water again.

The fuel pump it comes equipped with is a 0388685 as per the Marineengine website. I have found the replacement online for 70 bux. In an attempt to save a couple bucks does anyone know of a rebuild kit for these pumps or if a sierra 18-7350 can replace it? They look similar and believe I saw a thread where it came into question but never found an answer.

I have no issue paying the 70 bux, but im sure we all like to save, dont convict me.


This is my 0388685


This is a sierra 18-7350

Everything from the stacks,nipples, hardware and mounting gasket(not shown in the image) seem to match up. But i dunno

About the only thing you would need for a pump like that is a diaphragm.---Readily available.----Infact I am installing one tomorrow on a 67 model 6 HP.

I accidentally posted 2 identical threads on this matter. In my other thread I received a bit of info but not a complete answer.

In my other thread I was referred to the fuel rebuild kit #393088. I read about this kit but I was under the impression it was for lower HP fuel pumps. Think that kit will work for my pump? From how it looks this kit covers the diaphragm as well.


The previous owner informed me fuel sat in the tank for 4 years. He then went ahead and tried to pump the fuel through the siphon pump to demonstrate "the fuel lines and pump are good" while showing the motor to me. A ridiculous amount of garbage immediately stained the fuel filter. Don't wanna take any chances after what I witnessed.

I already cleaned the gas tank with denatured alcohol and a few bearings from my be gun, changed the fuel filter and ran new gas thru the lines until it came out clean.

Also changed lower unit oil, plugs, and ordered a carb rebuild kit, coils, magneto kit, impeller kit, the little pin that slides on the shaft allowing the propeller to spin, and propeller bolt. Hopefully this is everything to get this thing pushing water
