Topic: Fuel tank latch hardware idea

[Fabricator]

On my '73 750K I took the fuel tank cap/latch assembly off for a proper paint job on the tank.  The original latch hardware would not drive out, and had to be drilled; rendering them garbage.  I measured for roll-pins, but realized that they would be a hassle to install around the latch spring.  I found that 4-40 machine screws are an excellent fit in place of the original pins.  I used one #4-40 x 1 1/4" long 18-8 stainless steel pan head philllips and another 1 3/8" long.  I secured them with nylon locknuts.  The total cost was under $2 at my local industrial fastener house.  These could also be ordered from MC Master Carr if you do not have a good vendor nearby.

Hope this helps someone!

I am painting a tank right now and I might use your idea when it's time to put the cap back on.

I always try to save the pins, I know thats crazy, but sometimes I can reuse them, reflatten the end. but that's a pita compared to buying $2 worth of hardware. does it look odd?

Greasy,
 
  I will modify this reply with a picture as soon as I get home with my good digital camera, as my attempts are not working in the dark garage with the camera in my phone.  I am picky about appearance, and think it looks good.  The head of a #4-40 screw is only 1/4" in diameter, so they really aren't noticed.  If you measure carefully, and only have one or two threads protruding through the nut, you can keep it quite neat.

I want to use new pins on the fuel cap for my CB400F, but can't figure out a safe way to fold over the open end once inserted.
Thought of using a tapered tool and bashing it with a hammer, but knowing my lack of skill, would likely damage the tank in the attempt.
Any clever ideas on how to flare or fold the ends?

This is what I use. A machined piece of brass with 2-56 cap screws tapped in both ends. Cap screws come in any color anodized aluminum as well. That way I can remove them any time necessary.
