Gas Tank Install

So I started my 38 gallon tank install today. Now, it's time to vent

! Seems the PO decided to weld the trailer hitch to the frame. And...he welded the bumper brackets to the frame.....and he welded the mud flap mounts to the frame. Spent a lot of time cutting these stupid pieces off

. Now I'll have to find someone who can grind off the bumper welds, so I can install my bumper. Tank is removed and I will be soldering the extensions tomorrow. One more item to remember: It is much easier to use filler hose that does not have the metal spiral built into it. Rant over.

Don't ya love it? My Bumps' dock bumper was welded on.. there are still a couple of remnant steel bar under there cuz the leaf shackles are in the way... soon to be excised to make way for a fuel tank from an International and a bolt-on hitch.

Metal spiral = anti-collapse spring.

We must have had the same previous owner. I had to do the same on my 87. Used a cheap angle grinder to smooth out the welds.

Yes please keep us informed. I'm going to replace the sending unit on my 79 this summer. Might put a bigger tank in it.

Once the welds were cut off, the tanks was real easy to remove. The next step will happen on Wed.

My tank is installed with the exception of two bolts that will need to be modified. I did manage to squeeze in a mod for this that may be helpful to any future hose replacements. Parts can be found on any dent at the yards.
1) Get the rear hose filler neck and cut off the vent pipe. The welded portion just takes a slight hit with the hammer.

2) Make your angle cut that will mate to the gas tank

3) Attach the gas hose and mark where the hose will end for clamping purposes

4) Next angle cut the side that will connect to the tank. The angle should make the hose come out 90 degrees from the tank

5) Early sign of what you will have for the tank

6) After clamping this to the tank, install tank for pre-fit to observe any trimming that may need to be done. I needed to do this just once.

Once finished with final cuts, install tank and it should look like this.

7) A closer look shows what the clearance looks like at the tank

8) Finish install with hose connection to filler neck (including 3/4" hose)

The most obvious advantage is that there should be no more hose collapsing. A secondary advantage is ease of changing the filler neck connection. Final install pic tomorrow, after I get the rear bolts hooked up correctly.
