Fuel Pump for 1977 200hp Johnson

Hey,
I've been searching for quite awhile and can't find a rebuild kit or a pump for that matter to replace the top fuel pump on my 1977 200 hp Johnson. I took the part # from the Johnson web sight and tried to search that with no luck. I've also contacted the only two boat dealers local and they aren't much help. One says there is a rebuikld kit the other says no but the one that says there is one can't get it for me because it doesn't come from one of his vendors.
It seems that there are only kits for 1982 and later models. Any help or advice would be appreciated.

Thanks,
Buenos
