350x Leaky Gas Cap

[Tom12254]

Does anyone know where to get a replacement gas cap seal for the 350x? I can't seem to find anything even remotely close..

Wouldn’t the ones for the trx300 fit? I’ve bought some oem ones from partszilla

For certain TRX300 model years yes, I've been searching and even in Honda part diagrams I can only find the gas cap (which is discontinued) part #17620-HC0-003. But they do not list any part number for the actual gasket under the cap..

Hmm I'll give it a shot, I'm just not sure if it will fit because the gasket on the 350x and some TRX300 models have a kind of lip on them idk how to describe it really but it kind of hangs out under the gas cap while its on the bike. (you can see the gasket sticking out alil bit) Im just not sure of the part #

I've never seen the 86/87 200x, 350x rubber seal for sale separately. Should it be out there somewhere yes but finding the part number has lead me to many dead ends. Now if i only had a partsfishe (sp) reader that may actually have it?

i have other pics of it (rubber part) this is a just a test to see if pics load through this site-

contemplated a few times making this rubber piece for a while "but" being in close contact with fuel (the ethenol) i dont think it'd hold up.

Hey, i can actually load pics the old way through 3ww.......yay

YES! That is the gasket I need! Are you looking to sell that one by chance..? LMAO. That would be a good idea to make some, as you said though it would probably need to be a certain kind/grade of rubber to hold up next to the gasoline.. hmm
