The fuel pump I’m using on my new 235 will be the one I pulled off the 216. Every time I see fuel pumping through that glass bowl, I smile! I think it’s one of the coolest things under the hood of my old stovebolt.
The fuel pump rebuild isn’t complicated. And although the existing diaphragm looks salvageable, a failure of the diaphragm allows fuel to flow right into the block and rest in the oil pan!
A rebuild kit is $40 US. A new pump is only $60. I still plan to use a rebuild kit, mostly because of the “Made in Canada” stamped on the body.
To clean it up I pulled it apart, and let it soak in carb cleaner over night. Polished it up with a small wire wheel on a Dremel, and what you have is a renewed 60 year old fuel pump.
