I am in the process of getting a fuel pump for my 1980 Evinrude 7.5 hp, since it didn't have one when I bought it. The parts guy has a pump that goes on 99% of those small motors, but the parts computer makes a distinction between an "integral fuel tank" and an "auxilliary tank". The pump he has is for the integral tank, but every motor either one of us has seen uses a "remote" or separate tank. What's the difference between "integral" and "auxilliary"? I hate to ask such a dumb question, but I've never seen this type of motor with a built in tank.<br /><br />Mark
