I have been working on this for a few week now. Gathering my thoughts and not even sure it could work. But allas I went for it and am pleased with the results this far..
I have always had venting issues from my fuel tank. Dispite my effort in the past to replace, reroute and redeem my fuel filling issues, whether it was at the pump filling on the slowest pump setting possible or simply just sitting in the driveway on a warm day the fuel would always find its way to the ground via the fill neck.
While scheming on this idea I also wanted to increase the capacity from the original. I concidered auxilary tanks but simply adding one wouldnt cure my existing venting problem. Not to mention my untrustworthy fuel gauge.
I took a leap of faith and purchased a fuel tank modeled from a 79' ford bronco. I chose this because the dementions looked correct for the vision I had as well as an additional 10 gallons in capacity making it a 33 gallon tank versus the stock 23 gallon. I believe I will increase my range from around 200 miles per tank to a little more than 300 miles before refilling. This is a huge jump in range when you are out trucking around for a long weekend.
One compromise was to relocate the spare tire. Im totally fine with providing a home in the cargo area for it. Here is what I've got so far.
A pinched sending unit wire may have been at fualt for my inconsistant gauge readings causing it to detect an abnormal resistance input.

The new sending unit has an ohm reading range from 9ohms (full) and 76ohms (empty). I believe the oem was 0 to 100 ohms. Dont quote me on that.
I want to keep the original fuel gauge in the dash and in order to correct the differance I aslo ordered a sending unit/gauge interface from Speedway motors
I added some supports to hold the tank and mounted them to the frame

I made straps that were about 42" long out of some 14ga flat bar and bent them to shape, by hand.
I am able to use the oem filler neck but did need to add a 45 where it attaches to the tank.

I dont think it hangs down too bad myself

Also, the new tank is supplied with a rollover valve and a 3/4" venting bung. I will reduce the hose down to fit on my filler neck nipple. I think this simple design is going to make a huge improvement for me.
I will be installing the fuel gauge interface soon and will include photos of how I do that

Nice work! Is the top of the tank resting against the body, or is there some kind of padding?
Nice find on the Bronco tank. It doesn't hang down any more than a LRA 55 gallon tank.
Can you post a picture of the front of the tank to show the clearance there?

Thank you, Yes, I placed a piece of rubber between the top of the tank a the body.

In case anyone is interested.
I purchased these from, Jegs.
You'll also need to source a grommit for the roll over valve. Only a few dollars. Found mine after the fact on amazon.
Also keep in mind the sending unit has different ohm resistance than factory so get a gauge interface (like I did) or an aftermarket fuel gauge that is compatible.
The hardest part of this project, for me, were the straps. You can find 33 gallon bronco tank straps online.
The last thing is the sending unit pigtail. I found mine at tomsoffroad.com for $13.

Bought this factory fj80 filter/airbox from a fellow mud member over two years ago! I finely tossed it in this evening. I am using a 3.5" hose to couple the airbox outlet to the Holley carb hat. The box inlet will be consuming air from the passenger side fresh-air vent (at least thats the plan for now). Gotta cut a hole and and add a 3" nipple and hose to the fresh-air port. It should work, if not then it will stay like this.... after some clean up of course. Nevertheless, you get what Im trying to accomplish here.

I had unfortunetly misplaced my passenger front amber reflector. I think it fell off the fender one day when I was out beebop'n in the field. I search and searched but never had luck locating it.
I did see one on Ebay for $550/pr. Way too much....
Luckly, I found Cruiser Cult. For $28 I purchased one of their amber reflectors. I had to modify it of course but for cost saving sakes, it was well worth it.
If I were to do it again I would not weld the studs on the back but rather use rivnuts or something like that. The problem with welding is the heat melted the reflector a bit.

Nice work. I have all four originals from my 1969 sitting in a box. They are not in great shape. Rusty and out of 8 posts only 3 are still on the back. The rest apparently are gone back to the earth. I don’t think they have been on the truck for a decade or longer since the actual body panel holes were filled in.
Love these 'out of the box' mods
The fuel tank info is priceless!

That's a great mod. I wonder if you could pop the reflector out to allow easier welding. I'm guessing it's glued in pretty well though.
