So, if i'm reading a chart right, the aluminum 43.5# tanks are 12.3" in diameter, with an overall lenth of about 34" and a tank length of about 28". Steel tank in the same size is about 20# each heavier on the tare weight. Trying to fit two of them behind the seat here....

should be able to squeeze them in.

 

2 - 43# tanks is a lotta damn fuel no?

 

only 20 gallons... is that a lot for 3 days of wheeling?

 

Not a lot, that may be not engough, Id only run about 2days with a stock 350 on a OHG450 with two 40# tanks. Depends on the haulin ass factor. Most trips 1 tank is plenty for all day. I like to have one full tank and some reserve in the other tank for just one day of wheelin. so for me 2 days but Ill have like a 5 gallon reserve commign back to camp but kinda risky for day 3 to head out all day with only 5 gallons or so.

I think mounting two 40# vertical would be easiest to get to.

I would use two forklift straps per cylinder. The 30# and 40# tanks are the same diameter and thats all that maters if you use the forklift straps.

 

are you dead set on having that third seat? looks like you could easily fit two running parrellel where that seat is and still have a little room for a cooler.
looks like that seat doesnt have alot of head room anyway
most of my buddies with a v8 have two tanks just in case. i have mine setup to run two tanks but only need one. i throw the second one on if my main one is low
here's how mine are mounted
the rectangle in front of the winch has holes for tank brackets so i can put another tank there

 

that pic is older, the seat has been lowered 4" or so. And yes, third seat will need to stay. Is it bad to run them vertical?

Is that a 43.5# tank there muddyblzr?

 

ya that's a 43.5 lbs one i dont see why you can run them vertical the pickup tube is at the bottom.
i've been told it's best to run them horizontal slanting down. that way the pickup tube gets as much fuel as possible but i have yet to have a problem how mine are.
i think they ready better horizontal
if you need measurements i can get some

 

i'm pretty sure i'm running the 7.7 gallon tanks. standing them vertical, they run fine and the gauges are guesses anyways even when horizontal. after a few trips you'll learn when you need to swap tanks.

if you're running 2 tanks, make sure you leave your hose long enough to be able to unhook it from one and hook to the other and you don't have to move the tank over. that's a big pain in the ass. if you're really good, you could plumb both in, just make sure you keep one valve closed or it'll try and fill the other tank and then you'll be completly outta fuel at a bad time LOL.

and get a cap for the other tank so when you dont have the hose on it it wont get full of mud and dirt when you need to use it.

 

I run 2 of the 43.5# tanks for my thirsty V8. I guess they are 10 gal, but every time I fill them from empty I get charged for ~12 gal:shaking:

I just backhalfed the buggy a few months ago and made a new mounting system. My tanks are steel and weigh around 90 pounds full. So I made the back open like a pickup bed without a tailgate. Sucks lifting those tanks over the old tall tubes. Tanks just slide on the 3 tubes. Holding them in with ratchet straps right now, but I am building some elaborate metal straps for a longer lasting hold down. Just haven't had enough time to finish them yet.

 

I run one 10gal tank and keep a couple of spares on the trailer. One tank usually lasts me a full day of wheelin with my 396cid. On arelated note, I am trying hard to find a small (1-2gal) tank to set up as a reserve tank. I know I've seen them beofre but can't locate a source. Anybody have an idea? What are others using for reserve fuel. I have run off the small green throw away bottles in a pince nut they are only like 1/8 of a gollon - not going far on that!!

One tank will last me most of the week-end but it gives very little warning when it runs out. I pretty much have to run them empty or else I get screwed when its time to fill them. I dont have room for a second tank or a BBQ tank.

You can also look into a motor vehicle tank. They come in many different sizes. I have a 28 gal. tank in my Jeep. I have the stock I6 in mine and use about 15-17 gal.'s on a 3 day trip. I went with that big of a tank so I never have to worry about running out. The way the back of the jeep ended up I cannot remove my tank. I have a 7 gal. forklift tank as a spare that is mobile.

This is where I mounted my tank.

I access the tank from the back.

My spare tank

 

I ran 33# tanks because they where available at work when I had an LP rig but given a choice the capacity of the 43# tanks make them seem like a better choice.

I think that for off angle operation vertical is petter as it is less likely to uncover the siphon tube.

My 350 would eat a tank in a day, sometimes a bit more depending on how I drove and that was with the 33# bottles. I carried two but only pulled off of one at a time to make sure I would always know when I was at 'half a tank.'

Just a plug for a great company, if you need LP parts, tanks, brackets, etc try giving Hendrix Industrial Gas Trux (the 'x' stands for xtreme ) a call; they are one of the oldest and most helpful companies in the LP fuels system industry. I recommend talking to Todd.

 

Heres mine 2 of the 33s

 

The research I have done shows that most people prefer running the 43.5 tanks, and I plan to run one in my amc 304 anemic powered machine. I will probably eventually set it up for 2. I am gonna mount them horizontal in the tub of my wrangler. Don't want any way of anything puncturing them. Oh and brand new tanks from swift forklift parts are the best price I have found on egay----------------------just a heads up:grinpimp:

I normally run through one 33# tank for a full day of wheeling with my 360. I carry a second one with me just to be on the safe side. I'd LOVE to ditch the second tank in favor of really small backup tank.

 

I was going to post up a pic, but you already took care of that for me! :laughing: Glad you like it.

Just a note, mine are plumbed into a T-check valve with both tanks hooked up. When I run out, I just reach back and open the full tank.

 

nice looking. you fab that mounting setup or buy it?

 

Actually, I asked a friend to just bring me some scrap steel from his shop. He asked me some measurements, and then fabbed the base and sides at his shop. All I got to do was weld the rings on the base, and my tab for the check valve. Then I just drilled some holes and bolted on the tank brackets.

 

so your check valve only allows the pane to flow in one direction right, that keeps it from trying to fill the other tank? or you close the one, then open the other, and that solves it, or what?

 

For some reason I still have to close the low tank before I open the full tank. If I don't it will start to fill the other tank. When I first bought it, I thought that I would be able to let one tank run down to the point where it was getting low, then open the other and draw off of that one, but it doesn't work that way. I do know that the t-check valve will hold the propane between the T and the evaporator for a very long period of time though. The check valve must be between the junction of the T and the main line to the evaporator, not between the two feed lines from the tanks. I always like to run one of my tanks as dry as I can, then close it and open the full one. It seems that I always FAIL to judge when its going to run out, and end up poopin' out in the middle of a hill climb or a long mud drag. :laughing:

As far as consumption goes, I can get about a day and a half of semi gentle trail riding out of a 33# tank, or about 4hrs of heavy throttle assaults with my mildly built 454.

 

dang, it's hard to find 43# aluminum tanks without having to trade a kidney for one... anyone have a source for nice used tanks, or cheap new ones?

 

Guy up here can get them for $50 a pop for used ones.

 

I use 2 43 #der's. I will burn through both tanks in about 6 hrs. in the sand dunes. Granted I have a big thirsty motor and running full throttle most of the time. I will burn through about 1.75 tanks running pritchett in Moab if I drive from the hotel and run the hole trail and drive back on the highway from where it comes out by BFE. You can see in the pic. that I stacked mine flat behind the rear seat. With the top tank forward of the bottom tank it leaves me just enough room for a small tool box and cooler.

 

I'm using a BBQ tank as my back up spare ........ well I havent used it yet but I have the adapter to

Oh, and I'm using the see through fiberglass tank

 

Anybody that has a wrangler................How long is your propane hose line? Anybody know of a cheaper place to get it than egay!! I know go out and measure the jeep for it but I am not able to get to my Jeep for a few days and I wanna order up some lines asap----------------Kyle

 

43# tanks in general are not that easy to find; they are not commonly used in material handling. The aluminum ones even more. I would talk to every propane supplier in your area for used ones.

Buy hose in bulk through a place like Hendrix Industrial Gas Trux or talk to your local forklift shop about making one for you; most of them get bulk hose and screw together fittings for far less then you can though after market lift-truck parts houses and will make any length you want pretty cheap.

 

fo sho... let me know.

 

To all you guys running your tanks vertical, do you seem to use ALL the fuel before refilling? Any downsides? Im pretty sure they were designed to run horizontal, but if I can run them vertical it would save a bunch of room.

 

They are designed to run both veritical or horizontal.

I use a fork lift bracket bolted through the bed.

When I had the pickup bed on it I ran two side by side in the bed. Now the spare stays on the trailer. Typically get a little over a day on the trail from one 33# tank. But I'm only running a 22r.
