[baz69]

hi all,just in process of putting bike back together,took fuel tap off tank to clean ,question is when putting back do i need to put a smear of sealant on fuel tap rubber seal, or just replace seal or both replace and sealant,seal isnt perished just dont want a leak from tank

I've never had a problem with just using the rubber seal, but if you want to use anything on it use rubber grease so as not to perish the seal.
