petcock fuel filter won't stay in?

CynicalC · April 6th, 2011, 03:05 AM

Cleaning out the tank. removed petcock. Removed both filters to clean them. The filter for the main pickup slips over the end to stay in place. The filter for the reserve pickup fits into a recess. When I pulled the filter out of the reserve pickup all kinds of gunk and corrosion came out from the recess it sits in. Now that it's all clean, the filter fits very loose and I'm afraid it will just fall out... Is there supposed to be some kind of putty I use to get it to stay in place?

I was just cleaning out the fuel petcock on a Kawasaki dirt bike that has pretty much that same arrangement for the filter screens. As far as I could tell, the filter screens are a press fit. I'm guessing you had so much corrosion that when you you cleaned out the petcock, you must have taken out enough of the corroded aluminum that there is not enough for a good press fit anymore. My solution was to purchase a used petcock in better condition. I had been thinking of just running an inline filter in the fuel line going to the carbs. That would work.

Yeah I scraped a lot of crud out of there. I figured it was some kind of adhesive or something I'd have to reapply. I guess I'll just ditch those two filters and use one in-line.

Also, after cleaning the tank (letting 5 gallons of vinegar eat away at the rust), is it really necessary to seal the inside with por-15 or kreem? There were huge clumps of rust from sitting for so long but I think I got it all. Is the tank likely to rust again or should it be fine after it dries out?

to be sure, I'd recommend you try using something like this to insure all rust is removed.

Thanks. I just check and it looks like I got it all, or at least what I can see. Now the question is whether it'll rust again if I don't put fuel in it right away. I guess I'll give it a good douching and dry it with the heat gun stuck inside then seal it up good and hope for the best.
