Banjo Washers

[sailaway78]

When I posted up about finding the vacum leak in my fuel system, there was an interesting post by Kloudie1 that just in case you missed, is well worth knowing. I had found some fiber washers at Ace Hardware, that work well for the Yanmar banjo washers, for 45 cents each, and had posted that. Kloudie posted up that he found some copper oil pan drain bolt washers, in metric sizes at O'Reilly auto parts, that had the exact ID and were a little larger OD, but worked fine. I had not thought of that, and it sure sounds like a winner. So a reminder, lets all keep our thinking caps on straight, and keep in mind that it does not have to be Yanmar, or marine, or expensive all the time to work.

Any good automotive speed shop should stock banjo washers. McMaster probably does too.

Speaking of McMasters and Split Rings...

...inserting a modest subject rerouting, I was very unhappy with the split rings I purchased at WM since they unraveled very easily. Not a good thing on turnbuckles and they turn into meat hooks. I wanted some of the 'old kind' Found them in S/S at McMaster Carr, bags of ten for $6 for one inch and $10 for 1 1/2. WAY less than WM, one day delivery and really good quality.

I take it the fiber washers are diesel-proof and stay sealed over the long haul (?)

"Nylon" washer top of engine fuel filter

The last time I bought Yanmar washers (a bunch) they gave me some "nylon" washers to use on the center bleed screw on the engine fuel filter. At least they look like Nylon because they're plastic and a milky-white color. If I remember right, the reason they changed to/ or recommended these, is because the center screw strips easily.

I saved my old engine fuel filter case with the idea of drilling and taping a larger hole for the center bleed screw so I could re-use it. That was probably 15 years ago now and it's still rattling around somewhere in the garage.

Nice n easy: Amen on your post. These copper washers are expensive and they need to be changed basically whenever that nut is loosened enough that the washer can move, which is not much.

It would be good if someone who has access to a Rockwell testing machine could determine the hardness of the Yanmar copper washers and compare that to those found elsewhere.

They need to be sufficiently soft to work properly. A college with a good engineering department should have a hardness tester and I wonder if a prof would allow one to use it or allow a student to use it and do a comparison test of various washers.
