Best way to plug petcock holes while derusting tank?

[treejay]

Yes - remove the fuel tap and the filter will just pull off, it's just a push fit.

Are you sure? Is this true for all GS petcock filters? Attached is a pic of mine. I tried to gently remove it and then with moderate force, both with no success. I don't want to break it because that's an automatic new petcock purchase (which might be a possibility anyways). I want to remove it to make a plug to clean my tank (as described earlier this thread), but also to inspect and clean it thoroughly.

At least on my bike it is a simple pull off and push back on. To me, that petcock filter looks about shot anyway.

Here is a better pic. Is this filter/screen removable? If so, any tricks on how to do it?

Nevermind. Got it out. Thanks,

So, pray tell, so the next poor sod who does a search on it knows how this works.....

Hi,

Thanks for the response. In your article using Evaporust, you mention using a rubber stopper on the petcock hole. How did you find one that was oval shaped ? My petcock opening is oval and I doubt a circular rubber stopper would work. They'd work well for the bolt holes though... But so would bolts and o rings...

The cool thing about rubber is that when you shove it into a tight space it will usually expand to fill the area. I used a round rubber stopper in the oval hole. Just make sure it's big enough.


Thank you for your indulgence,
