I'm curious how you will hook up the two fuel tanks and/or manage the
switch over. If you draw from both tanks simultaneously, there is a
very real possibility that one tank will run out before the other.
When that happens you will draw air from the empty and the engine will
shut down even though the other tank still has fuel. What I've most
often seen is quick connects on each tank and a single feed hose. When
one tank runs out or gets low, you just move the feed hose to the
other tank.
....
Good question Wayne. I should have clarified that I won't be drawing both sotaniously. That's my bad.
Fuel transfer solenoid a are in expensive, so I thought of running one tank for a bit. Then switching to the other and back and forth etc.
Can manually do the same with a 3-way ball valve too.
On such a small craft, carrying 150lb in in fuel, I'd like to keep even trim as much as I can. Kind of a pain but doable. Can't use bottom fed fuel tanks on gasoline marine.
I wish I could.


I love quick connects... Although the idea of using solenoid to do a
tank switch is something that should have occurred to me...

I know its nowhere near the same situation, but I have two 6 gallon
tanks in my Forrester. If I'm just out fishing, I only take one tank,
but if I'm out to play (ski, tube, just run around the lake) I bring
both tanks and switch off. Like you said, kind've a pain, but doable.

How long are you thinking your trip will be?
