I need to clean out the gas tank and eventually get it painted. How do I remove the petcock?

Remove threaded bowl, remove round strainer, remove 3 JIS screws - DONE.
Thanks

Thanks! Just what I needed. There are 2 pieces of rubber... 1 is an O-ring under the bowl and one is under the valve handle. Both seem to be in excellent condition, but should I replace them just based on their age?

Yes, I always replace since 55 year old rubber may not seal well. I also replace o-ring on top of fuel petcock & banjo bolt washers. YDS Parts in UK has quality reproduction parts.

Good luck!!

Fuel filter if needed:

You are my new best friend!

Just curious. Why replace the ones on the banjo bolts? They are hard and don't move. Can they wear out?

Should I also replace the strainers if they also seem to be in good order?

I replace banjo bolt washers as they harden over time which can create another opportunity for fuel leak.

If strainer is not damaged I'd reuse it.

Thanks
