easy question, possible stupid question
so it looks like im going to fab some auxillary gas tanks for my boat. im thinking 1/8" will be thick enough. what do you guys think?
also im thinking of putting a "low spot" (sump) at the bottom of the auxillary tanks. the 2 auxillary tanks will be positioned higher than the main tank in the belly of the boat. i was thinking of having this "sump" drain directly into a "T" on the fuel return line to the main.
my theory is that as the main tank loses gas the 2 auxillary tanks will automatically gravity feed the main tank. does this sound like it will work?

no if the borrom tank is not sealed up completly air tight it which im sure it has a vent and the fill cap is olw also. the top tank will just drain in and over flow the bottom tank

Here is a post where I made a tank for my car.

As far as the two tank set up goes, you can hook it up like you said, as long as the top level of the two extra tanks does not excedes the top level of the main tank. Or you can put them higher and move the vent from the bottom tank to the highest tank in the system.

Re: easy question, possible stupid question
both the auxillary tanks will be positioned physically higher than the main tank. the fill and vent tube of the main tank is positioned higher than the auxillary tanks though. make sense?

Re: easy question, possible stupid question
wont the pressure from the 2 aux. tanks push the fuel up and out the vent and fill cap of the 1st?I dunno, these things confuse me too.

Re: easy question, possible stupid question
i dont know. i didnt think they would because the fill and vent of the main tank is set higher than the auxillary tanks. i guess worst case scenario i just put a valve in there to stop flow to the main tank until i see the guage get low. that should cure all problems.
i will only run these tanks 2-3 trips a year when i need the extra gas. i would feel plenty comfortable with 100-110 gallons for these trips. 60 just isnt cutting it.

Re: easy question, possible stupid question
so if everything has atmospheric pressure on top, than as long as the filler and vent are the highest, it WONT over flow?
