got my second bike almost finished. it didn't come with the little red petcock washer/gasket. can i just use teflon tape on those threads for now? i found several articles on the internet saying that it (white teflon tape) will dissolve in gasoline if given time, and some specifically saying it is the "preferred" method of sealing the petcock valve. i would think it should be ok to at least use it temporarily, until i can get a real one... so what say you, wise old sages??? will it really stop up anything if i use it for a week or so??? note: yes, i know about the yellow teflon tape. but i don't have any of that kind... and it's easter sunday... lol. BTW... Happy Easter!
