extended range tank for cheap - mud co-op

[srplus]

xactly spook

baffled tank is available at MAF. gas weighs approximately 6.25 lbs (depending upon ambient temperature) / gallon x 38 (slam full up to the filler cap) = 237.5 pounds... if the fat lady falls out of her seat belt is the car gonna crash?

all i am interested in is an update... saving all of my argumentative skills for pirate boards.

I think you missed the pun, dude.

pun? I didn't see a pun, because none of us were ever close to being baffled by this project.

there is no place for her to fall out of her seat in my fj60. I think Jim has already agreed that I have a point about that kind of weight shifing in a 38 gallon tank when avoiding road debris in the middle of the highway when you are going 70 mph, especially when driving an fj60 with a 3inch lift and tall sidewalled tires. again, I am not trying to convince you to be concerned about this. please don't try to convince me that my concerns are trivial. I might actually opt for baffling my aftermarket long range tank, or, spending the extra money on the MAF tank.

I'm baffled about everything.

So how goes the Tank experiment?

You are being too sensitive about this. No one was trying to convince you that you have unfounded concerns..

Buck up camper..

ttt - where are we on this?

FIRST PREVIEW THE FOLLOWING THREAD AND SEE HIS PICS OF GAS TANK: https://forum.ih8mud.com/showthread.php?t=34899&page=10 POST # 283 - ISN'T THAT PRETTIER THAN A JUNK YARD TANK?


To raise this from the dead:

jim... would it be too hard to get the measurements for the tank and placement of the fuel fill when you are doing the ford or chev tank? i will then proceed with setting it up in cad and then get some prices. one of the nice things about these aluminum tanks is that they can be shaped to fit the hole precisely AND tabs could be welded on them for mounting to the frame with some bolts for a nice clean install with no straps and crap. i'm pretty sure that the price would be equiv to the junk yard or new ford/chev tank install... for sure the labor would be far less. it was a long time ago when i had any tanks built for my boats but their cost was less than the cost of the replacement tanks and one of them was a 50 gallon that was custom shaped to fit in the Vee on the bottom of the hull in front of my center console on my 25' boat and those tanks were baffled to keep the fuel from swishing around when hopping waves. and for you rock hoppin' boys there could be provisions for a skid plate that mounted to the same frame rail bolts as the tank uses.

let me know by email to the link in my sig line.

thanx

another twist: does any one have the MAF tank or the Aussie Long Range tank that can get the measurements... i will put them into cad and get the quotes to have some custom "WATER TANKS" with baffles made that will fit where the stock tank normally does. if i get the measurements i will also have this "WATER TANK" have the same connections and holes as the stock gas tank so that people can use their old gas gauge to determine how much 'water' is in their tanks.

i was re-reviewing Waggoner5's build up of his 1965 FZJ45 Pickup on modified 80 chassis and saw that he had a custom aluminum anodized tank with baffles built (smaller though, 24 gal or so IIUC). i PM'd him and he said that his total cost was about $ 500. see entire build up thread: https://forum.ih8mud.com/showthread.php?t=34899

As i posted before - i am sure we could have a custom tank built (especially, if there was more than one built at a time) for WAY under the MAF price and prolly very competitive with the junk yard 38 gallon ford adaptation. of course the ford would be DOT approved for gasoline and we would only carry water in ours.

I for one am not concerned with baffles, but the fuel starvation is an issue for off camber situations and is a concern to me on my FJ62. Instead of running foam (which I have heard comes apart over time from a racer buddy with plenty of experience in Baja amongst other places) Id run an accumulator. For those not familiar, here are a couple designs and some explanations to back up the idea

1.) Wild Child Accumulator
http://www.awildchild.com/accum1.htm
Our accumulator tank is filled from a supply pump (you can use your mechanical pump if you are converting to a TBI). The tank is kept full and the air is purged with a return line to the tank. The high pressure pump draws the fuel out of the accumulator tank, the motor also returns to the accumulator tank to maintain fuel as long as possible.

The accumulator tank holds almost a quart of fuel, this will run a 5.0 for about 5 minutes with the fuel pickup in the main tank sucking air. As soon as the gas sloshes back over the fuel pick up the accumulator tank is refilled. With a standard off the shelf electric fuel pump the accumulator tank is filled in about 15 seconds. This means that if you get fuel to sloshed over your pickup for 15 seconds every 5 minutes your engine is still getting fuel.

Priced $ 90 including mounting bracket.

OR 2.) Accumulator with filter from BC Broncos and Wild Horses http://bcbroncos.com/store/product_info.php?products_id=119
if you allow your fuel level to drop to a point where the fuel can slosh away from the fuel pickup in the tank the FI pump will pick up air. With the stock EB fuel plumbing that air bobble must pass through the fuel pump and injector rail if you have a return. The air in the fuel pump will cause the fuel pressure to drop or will pass through the injectors, either way the engine will run poorly for a time depending on how much air was suched into the system. The fix is either a intank pump or a accumulator tank. With my acc./filter the fuel and any bobbles will be pushed into the filter/tank, the air will rise and the fuel will filter. The air will return t the tank. The fuel will be picked up from the bottom of the tank by the FI pump and sent to the fuel rail and injectors. The unused fuel will either return to the Acc/filter and be reused or will return to the main tank. The Acc/filter will hold about 1 qt of fuel. The kit includes the mounting hardware.
Price $70

Real work has been keeping me off the fuel tank project recently.

I have not heard back from the guy selling the in-tank rated fuel hose. I sent an email last week. Will try calling him tomorrow during business hours. we need to know what diameter it is, and if he sells it not already chopped up into 6" pieces. I am still looking to go with the Klunk pickup, to combat a low fuel level fuel starvation possibility. There are more positive ways to deal with the problem (multiple pickups, surge tanks), but I don't anticipate severe rockcrawling with an empty tank.

 

[dieselcruiserhead]

Jim, I've been looking at this tank for a year or two, thinking the same thing:

http://www.rockauto.com/catalog/catalog.php?carcode=1059320&parttype=6268

http://www.rockauto.com/ref/SPI/Det...ecs.php?part_id=GM25G&product_specs=fuel_tank

It's a 40 gallon tank from a late-'80's Chevy P30 van. Not sure if the filler is lined up with the short dimension such that it would readily mate with the FJ60's filler, but it's another possible donor tank.

Steve in TornadoAlley

I have one of these tanks around if anyone is interested in it, for what its worth..

 

[dieselcruiserhead]

FWIW, the GM P30 van tank is also unbaffled, and I'll bet the Suburban tank is also.

Jim, once this thing is installed and functional, it'll be interesting to see how it does off-camber.

Steve

Sorry just catching up here. . I installed one of the suburban 40 gallon tanks into a school bus once, it is also a big metal ballon about 40 gallons, but comes with a nice skid plate. Also no baffling as well

For those searching for fuel filter solutions like rockcrawler showed in his post, this item is available from West Marine: Stainless-Steel Fuel Water Separator Bonus Pack

http://www.westmarine.com/webapp/wcs/stores/servlet/producte/10001/-1/10001/221724/0/0/fuel filter/All_2/mode matchallpartial/15/0

Price: $ 54.99

Mfg: SIERRA Part#: 18-7776-1K

Have used this part in Stainless and Zmack and Stainless is the way to go. Most screw on fuel filters will fit this bracket... and this kit comes with two of them.

 

[Waggoner5]

As far as baffling and capturing fuel in off camber situations, all of our fuel tanks that we use in our boats have this built in. I like the idea of a replacement tank for the 60-62 that is relatively cheap to buy or produce, but I don't think any existing domestic tank will be the ticket. I have drawings of a tank for my 62 that has all the baffles and a boxed sump are for severe off camber stuff. I think it came to about 38 gal and has provisions for all of the stock hoses and electronics. Unfortunately I am not home to get the specifics, but I am sure that if enough people wanted them, I could get our manufacturer to make them reasonable. On the other hand, any of the existing tanks could be copied out of aluminum, and cost should be cheaper than the ones shipped from AUS. I would rather the members use a copy of an existing than to use my design. Mine is complicated.

gary: could you post up or PM me with the measurements or send them to my sig line email link?

 

[Waggoner5]

No problem. It will be next week though.

 

[calfj60]

Just wondering if there is anything new going on behind the scenes????

 

[CaliCruiser]

any updates????

 

[JimDaddy]

Why cant someone measure the available aftermarket tanks, post the dimensions, and then forward them to someone with CAD table? If we get enough people to commit to the deal, it'll be cheaper to produce. I know everyone doesn't have a welder, but I do and it sounds like a party to me. How thick are the tanks anyway? I'm in the SF Bay Area and I just bought a FJ60 a week ago so this is all relatively new to me. Jim, you still need cash?

 

[JimDaddy]

oops someone already had that Idea......I have a mig welder though, and introducing some sort of baffle wouldn't be a problem; just to slow fuel down and all.

 

[calfj60]

jimdaddy...sounds like an idea...just wanted to see how this whole thing panned out....
