i used the 2 stock gasket pieces. that collar thing that goes inside the pipe and the gasket that goes between that collar and the cylinder.
got a tube or red rtv silicone and used enough to make sure it wouldnt leak.
if it does leak after it cures for a day, take it all off, and reapply the silicone over the existing hardened stuff.
also, using all 3 springs for pipe help hold it nice and square to the flange on the cylinder.
as always, honda has a much better deisgn
