I recently picked up some mitsubishi fic 850ccs for my stock bseries fuel rail, but they didnt come with seals. I tried the seals from my dsm 450 seals but they didnt fit so I tried researching, but couldnt find anything. Is anybody running these or know what will fit? Any help will be greatly appriciated.

 

You need to use a new set of the oem 10mm honda o-ring seals in order for those to fit into your fuel rail. I believe you are at the limit of the stock rail , and may have to get an aftermarket rail, but someone else can verify.
