Here's an update on moving the gas tank from behind the seat.
While searching on line I came accross a universal tank sold by a Co. called Tanks Inc. Previously, I had read some good stuff about this Co. in Classic Truck magazine & also in this forum.
I chose a ss tank, 34"long 10"wide x 11"high. Here's the plan!
Install tank underneath, against the inside of the frame, passenger side, behind the cab, in direct line with original gas filler, cab floor, & top of the new tank.
Drill hole in cab floor in direct line of new tank filler hole
Weld exhaust pipe from gas filler area through the floor inside, allowing about 2" of steel pipe to protrude under the cab. A flexable rubber hose connection will join the underbed tank to the original filler, via the protruding steel pipe. Install new fuel injection pump same type as original Astro Doner vehicle.
What I like about this is, I won`t need an alternative fuel filler & door. No need to weld over the original cab fuel filler.
Both the spare tire storage and the original gas filler remain useful. This will keep the outside body looking stock.
I am waiting for the new tank to be delivered. I will post more pics as I go.
I have attached mockup pics of the plan.
