Fuel tank location options for long bed pickup

[Chris_oz]

Hello,

My 1970 C20 "longhorn" had 2 x dealer fitted auxiliary fuel tanks (they are on the invoice and order)

The are in front of the rear wheels, outboard of the chassis, the filler necks are in the wheel well.

They were hooked into the fuel system with a floor mounted manual 3 way tap/selector.

Mounts were long 1/2' dia bolts that ran down through the tank.

Fitted in 1970, still there not leaking in 2018.

They were just over 15.5 US gallons each.

Speaking from experience I guarantee those tanks are very rusty inside. Stay away from them. You'll get a lot of crap in your gas using them. I would use them. I had them and the best option is to either stay with your existing in cab tank or get a new rear under bed tank.

Hi,

The tanks are in my shed, I doubt I will ever use them, They do seem clean inside, but I have no need for them.

My truck had a 11ft Anza slide in camper fitted at purchase, I imagine the fuel use would have been high, hence the long range tanks.

Now it is just used for cruising, daily trips to work and collecting some firewood, the stock tank does me fine. I can get over 300 miles with ease before looking for fuel.
