3/8" flexible steel line from Summit Racing, 3/8" EFI hose, canister fuel filter before pump, clear glass filter before carb, using 3/8" hose only for the tank connection and carb connection. Most fuel cells are going to take a Chevy sender, so, consider a Chevy gas gauge. I would look at baffles or foam in the tank. For a daily driver I would mount it inside an ALUMINUM tool box with aluminum hinges. Opening a steel tool box might create unwanted sparks (boom). Ground the tank, ground the box. I think the ground would be from the filler neck bolt to the frame, BUT, whatever the maker suggests.
If you can, go for a sight gauge on the cell since gas pump shutoffs will probably not work with your fuel cell.
You probably want a vent with a roll over valve, I bought my valve at Spidertrax, I do not know if they sell them anymore.
