Extra Fuel Tank

OH, for these fuel lines with brass fittings, you'll want a double flare tool.

I sourced the stock brass fittings from these guys:
BRASS FITTINGS Brass Pipe Fittings Hose Barbs Stainless Steel Fittings Hydraulic Adapters Hydraulic Fittings Grease Zerks Hose Clamps

iirc You'll want inverted flare fittings for the fuel lines and breathers vents.

Oh, the Valve, was probably the most expensive part. (I already had the tank and pump).

just asking but where do you guys go that you need 100 gallons of fuel without seeing a gas station? i use my slip tank to fill up tractors.

If we stop to fuel up the zombies will get us.

Where did you mount the valve? Installation looks great, thanks for the photos.

The valve went down on the floor on the left side of the cab. I'm kind of skinny so I was JUST able to get up under there to do the install. I did have to fit the hoses to it first before I installed the left side tank.

Given the way the valve sits, I had to make sure I had enough hose for cab/frame flex and ended up having one hose kinked because of the route it took. This lead to fuel starvation for a little while on that tank until I figured out what the problem was.

here is what it looks like with the spare gone and a 50 added - did this to 2 trucks.

Ryan, if you plan on running biofuels in one tank and diesel in the other, you may consider the "flushing" operation. Switching supply and return at the same time (your manual valve) will eventually increase the contamination of the diesel to levels that will make it difficult to start the engine when cold.

Hey Zout, where did you mount your spare? In the rear b/w the duals?

when i did mine, i used just that brass valve. it was not that much, around $50 i think. also moved filler of second
tank (in place of spare) so it was in the front like the original tank. i have a source of those valves if needed.
