Does anyone have an auxiliary fuel tank?

Yes, got it at Northern Tool 10 years ago. No complaints.

I must agree this investment will serve you for years + it can increase the resale value of your truck.

I just gravity-feed fuel to the main tank using a ball valve on the outlet hose from the aux tank. Northern Tool has a kit that allows you to "T" into the fuel filler hose. You can easily access the fuel filler hose in the left rear wheel well.

I am sure this tip will be useful for other drivers who consider getting an external tank.
