Remote fuel tank

[markwade]

Hi all, I have recently purchased a 1998 4hp evinrude 2 cyl outboard. A fantastic engine its restored my faith in ebay. Anyway back to the query. My new outboard is equiped with a coupling point for a remote tank, I'm new to boating so have a few questions, if I use a remote tank is the fuel tap still in circuit or does it just serve the internal tank and if
the tap is still in use does the engine draw from the internal tank first then the remote or vice versa. I'm sure these questions will seem a bit silly to the more experianced but like I said I'm just starting out and its a whole new world out there!!

Might be valves and pipes too.

Thanks for the replies guys, I've had a quick look but thought I would ask anyway. There looks to be some sort of pump attached to the side of the engine, I don't think its mechanically driven so am assuming it might work on crank case pressure, I will know more when I have a better look. Must admit that the setup does seem similar to some of the old pneumatic instrumentation we worked on in the good old days, not many people seem to know what a tiffy is so I guess you are in the industry? myself, well we were absorbed into an electrical department years ago so I seem to spend about 90% of my time on industrial electrics nowadays, would never call myself a trician though.

Most small outboards that uses internal and external tanks must have a mechanical fuel cock. One position controlls internal gas tank by gravity, placing other position shuts internal tank and opens external tank through connector as this works with internal gas pump, will need to prime before starting engine.

Happy Boating
