    Where, exactly, are you planning on putting two tanks? There is no room for saddle tanks on a blazer.
    If you manage to find a place for it, it would be pretty easy to mount up the dual tank switch. I have a stock dual tank switch in my cab and I used a switching valve from JC Whitney.
    This is all in my longbed (40 gallon /forums/images/graemlins/smile.gif )

    I wanted to do it myself but the tanks will be exposed and I didn't like it.
    However on my Jeep wagoneer they fit nicely inside the frame with a body lift.
    The frame width on a blazer is 28" outside to outside.
    On the wag it's 28" inside to inside so they fit tightly and still leave room for a driveshaft.
    You don't really want them outside and exposed do you?

    I know it's nice to have a lot of gas, but even at 10MPG freeway, thats 310 miles...on a stock rig, why are you looking for so much additional? FWIW my '83 K5 consistently got 17MPG freeway travelling across the country. Even though that MPG is bad compared to a new car, it equals 500+ miles per tank.

    Not trying to be a naysayer, but is there another problem that needs resolved to make your gas last longer, or do you just hate filling up? /forums/images/graemlins/smile.gif

    I ran two tanks on a 76 K5. I had a 3" body lift and 5" on the springs. I ran the second tank bolted to the floor section just in front of the stock tank. This was a 20 gal tank out of a chevy monza. There was not a lot of room for driveshaft clearance with the rear stuffed but it never hit.

    Now that can be a viable option, a tank in the middle high enough and the flatter the better.
    20+31=51 that is some serious capacity.
    As much as my single replacement Van tank /forums/images/graemlins/thumb.gif

    I have dual tanks on my 76 Jimmy. It's a side saddle on the passenger side. It was on there when I bought it. It fills from under the rear wheel well. I can post some pics if anyone is interested.

    It was easy and cheap at the time. It was always fun to pull into a gas station and take up two pumps to fill the truck. The best part was that it allowed my BB Buick to make a regular 500 mile trip in about 6.5 hours give or take a ticket.

    I was looking into buying some aux. tamks, they would go in place of my rocker boxes on my 72. I would have 3 total tanks and I think they were 15 gal, each.
