Similar, here. Our outboard will run from either the internal or an external tank.
We can pump from the external (Moeller) tank into the internal tank, using the same (Moeller) fuel feed hose we would normally attach to run the motor
. An extra male fitting on the "delivery" end opens the valve so gas can flow. We replaced the original spring clips on the feed line with proper all-stainless hose clamps...
FWIW, extra male fittings on both ends of the fuel feed line allow complete drainage after use. (We usually do that, then store the whole thing in a zip-lock bag.) Or another way to drain is to reverse the feed line direction, open the unattached end with an extra male fitting, and pump back into the external tank though the installed valve.
