Here's a link to several options and sources for aftermarket pumps. The aircraft style you asked about is listed here and it, unlike the Mr Gasket, has the check valve. I used the Mr a Gasket because it was in stock at a local auto parts store and the other wasn't. Plus I always turn off my fuel when turn off the bike so hydro lock wasn't a concern
