Was just looking through my box of parts left to put on the FX1 and realized I dont have the seal/packing that goes between the pump and the shoe. Looking at OEM a superjet seal is around $20 and an FX1 seal is $50+. Do I have any other options to seal it up? I was thinking about either cutting my own seal out of a piece of rubber or taking a superjet seal, cutting a section out of it and then supergluing it back together. Do I have any other choice than dropping $60 on an OEM seal?
