FS2 has 144 tunnel - same as any sj - so some fiberglass work need to be done - is an RRP based pumpshue - made it thicker to be able to machine it so the wear ring to fit directly in it as yamaha runners have oem

Because when you try to fit an existing 155 aluminium pump shue on a SJ there is no enough space for rubber seal ring - that is not longer produced by Yamaha and aftermarket ones are very rigid ones. But oem 155 pumps on superjets/B1 are best freestyle improovement at very low cost(not for speed yes).
