Mostly. My thought was to put the connecting tube on the inside bottom corner and run it behind the transom supports so that it's the lowest part of the system. Fuel would pretty much always be even between the tanks while on the water as there are no 'hills'. I thought about a T fitting to the motor, but my first thought was just run it from the regular fuel pickup. That way when it gets low and I have to use my 2 gallon reserve tank, I could have 2 gallons in one tank instead of 1 gallon in two tanks. If so, i would probably open up the tank and extend the pickup tube to the back of the tank.
Fuel slosh between tanks would be limited by the size of the connecting tube.
my old 60's mini cooper has 2 fuel tanks, a fill on each tank and both are connected to a t fitting to a single line to the engine
both are vented individually and one has a gauge.if i fill only one tank, in a few minutes i have 2 half tanks
because the tanks are taller than wide and sit upright, they balance out well,but if tanks are low and one runs out of fuel(i had that issue parked sideways on a hill) it will suck air and not fuel, and if one tank vent line is not venting that tank will not drain (and that sucks when the tank with the gauge reads full and your engine runs out of fuel because i pinched off the vent somehow)
i am not sure how it would work with boat tank fuel tank outlet not being on bottom of tank and fuel hose above fuel level for gravity to equalize them .my tank outlets are at very bottom of tank and tank connector hose is below that
i think this is what you were asking?
Has anyone installed or considered the pros and cons of a fuel tank balancing system? With the refurb of my aft section, I'm considering making my fuel tanks more semi-permanent. I'm thinking a section of fuel line between the tanks with shutoff valves on each tank so they could either be run individually or removed without spilling.
No more switching tanks in the middle of a ride.
I could ride with my cover installed more often.
Refueling is more along the lines of a permanent installation (not a prob in TN, but my lake has no on water fuel stations)
With the cover installed, would venting need to be taken into account?
No 'halfway' indicator.
Another option is to reinstall my fuel tank selector switch.
Both. The deck is tight around the wire, and the board sits flush to the deck. Also, I'll need to cut the wire ends off in order to remove the wood trim for refinishing. So I might as well do it right. Make the hole bigger to accommodate a grommet and make the wood trim fit over the grommet. And while I'm at it, make it so I can easily take it apart again when it comes time to refinish.
Not sure what your refering to zero clearance, do you mean once the board is seated again to the deck?, if so, can you ream the hole on the underside of the board to allow clearance, or is the hole in the deck to tight, can you enlarge it to accommodate, just wondering
