This is something I'm sure everyone with a truck thinks about, how can I get more range from my truck? I'm pretty sure we've all pondered this.
I've known this is possible, but just wasn't sure how to do it. I have just figured out that the toggle switch needed is a double pull double throw.
I found the information tonight on the Tanks, Inc. website and they have a PDF with this info:
However, they charge $16 + they want $14 for shipping, so that's $30, and I found the same switch on ebay for $6 w/shipping...so I ordered one of those.

NOTE: you must use low pressure, 2.5-4.5 psi fuel pumps. Many of them are higher, like 5-9 psi, those are also low pressure but too high for the straight six. Fuel injection is higher like 50-60 psi. Caveat Emptor!

Even at 15 mpg, with 36 gallons you would get 540 miles range, and at 17 mpg you would get 612 mile range.
This only cost $24.52 for 2 fuel pumps and $6.03 for the switch, so aside from wiring/fuel lines/tanks, it's only $30.
