I actually bought a tank from a 55 years ago and had planned on running both the 56 and 55 tanks. Now, I would love to gain some additional leg room by getting rid of the 56 tank, but I want more than 16 gallon capacity. Maybe your suggestion on putting tanks on both sides is the way to go. Do they sell patch panels with the 53-55 filler tube hole? As far as the spare, I do not want to test fate by not carrying one. If you have one, you will never need it. The moment you are with out it, you will have a flat.

I thought I saw that filler piece in the Mid Fifty catalog, but it isn't listed in the 2005 issue I have at work. If you tied the two together, they could both fill from one filler.

I've apparently been on borrowed time running without a spare for over three years. I appreciate the caution....but, HEY! It's a hot rod!

Like you, I went back and forth about doing the move. One day, when I was again wiping up the gas dribble from my cab corner after the neck overflowed, I decided that was a deal breaker with new paint. So, the tank got moved. I think I'll also like a little more leg room with the stock tank gone.
Just a thought.
Woohoo.
Randy my friend, leg room is something I need not be worried about!
The thought of leaks in the cab is the thing that keeps me 2nd guessing myself.
Randy
How would you go about tying that 2 tanks together so that you use one filler?
Thanks

Fatfenders56 told me a way a while back, but I don't remember the particulars of it. He had a system once where he switched between tanks and switched between gages as well. Maybe he'll come on and explain it.
It seems to me that the two tanks could be tied together and used as one tank by plumbing a tube between each at their bottom, filling one from the top and venting the other to a level above the fill. Put a gage in just one to read the level of the two combined.
Switching between the tanks for the gauge and the fuel line is easy. I thought about your idea to tie the tanks together so that fuel from one tank can make it's way to the second tank, but that would require the line to be run pretty low. I can see something bouncing up on the freeway and taking out that line and draining both tanks or worse. I will have to keep thinking about that one.
Thanks

RJ ??
wouldn't that just give you a 'FULL" reading until the higher tank (or tank with most pressure) emptied into the one with the guage ??? I guess if the two were the same elevation your gauge would read F1/2E on a 40 gallon tank instead of two siamesed 20 gallons....maybe I'm missing something here.
This really ain't new science... you could probably find a shop manual ( Chilton or Haynes) on something with dual tanks and look at the wiring/plumbing there ??? And every 18 wheeler in the states has saddle tanks... should be easy to find an answer with a little Frooggling
found this... might explain how some do it... but it ain't what you wanna hear
I have searched this to death and I am ready to pull out whats left of my hair!
I am ready for a tank in my 53, and want to have it in the frame. I have searched gastanks.com, I think every one they have, and am more confused than when I started.
I like the setup tacson has in his truck, but when I measure my opening, the tank he used won't fit without moving the rear crossmember. And from his pictures, the crossmember looks to be in line with the springs, i.e. factory location.
Any suggestions, or should I bite the bullet and move that crossmember. I don't want to move it because I would like to retain the stock bumper mounts and install a hitch at some point.
1 digger the rear crossmember in my truck has not been moved. Did you measure for 77-80 Chevy/GMC SHORTwheelbase Van gas tank? It is the smaller of the two. My tank is held in place by the factory van tank straps where are bolted to the crossmember just ahead and right after where the tank is mounted. If you need more pictures send me a pm. Thanks Donald
I would install two electric fuel pumps and filters. T them after both pumps. If you need one way check valves to prevent back flow install them. Use a on/off/on switch inside car (dash Area).Run tank without gage first. Either figure out miles to switch before empty or switch when the engine stumbles.You could install a second fuel gage. Place filter before pump and both close to tanks. You will always have a backup pump should one fail. They do ocassionally fail. Have a great day,chuck
