To add to this for further reference, fuel lines for weedwackers ( same type in little outboards and types of application where a proper pick up isn't necessary) Will break down over time, a short time. You can go to a place like orilies and ask if they have under a foot peices of hose that will hold to fuel on both sides (it doesn't need to be pressure, but suction (dont want the hose kinking together.) Best of all under a foot is usually free, just like the waste bin at home depot.
If theres more interest for fuel cells, wiring, plumbing. Im the guy to help out with it. I design custom containers, to be contained anywhere. I can do clean wiring (almost aircraft standard worthy) plumbing (coolant, oils, fuels, water.)
Fit in live well for drift\jon type boats?
