1968 9.5hp fuel pump

[donnypack]

I need a new fuel pump for my 1968 9.5hp outboard and it costs around $100, what would keep me from using a new fuel pump for 1984 9.9hp, it is about half the cost and from what I can tell uses the exact gasket from pump to manifold so I am sure it will bolt right up, plus it looks exactly the same. Does anybody have any ideal why this wouldn't work just fine. From what I can figure out it's basically the same thing just cheaper. Any help out there would be greatly appreciated!

Might work not sure never tried it.

FYI, works perfectly! Saved almost $50 on what I believe is the same thing. Bolted right up and pumps the fuel perfectly. Now that my motor will start I now know I need a water pump.
