Aux Fuel Tank, the last Mod I want . . . . . . . .. . . . . . . . . OK this month

[TonyP]

I would sign up in a heart beat if I was sure I could get it installed. I asked Slee and he said he wouldnt do it as you never can get the emissions stuff just right and it would likely throw codes. I did install the aux tank in my 80- by myself. Didnt have to worry about the canister though

Ahh hell. I'm in for a 90L

Maybe Kurt will want one and then I would have a reason to drive over to cruiseroutfitters

Luckily (or unluckily) my 200 is still throwing evap codes occasionally anyways so I don't think it can get any worse adding an aux tank

After having to take an hour detour last week, while wheeling, to find a gas station, I was convinced.

The 90L seems like the perfect size, just large enough to make it worth the purchase and effort to make it work. Plus, it seems like the decent clearance as they call it the "90L Aux Hi Clearance Fuel Tank". I'm thinking well above the frame rails from looking at the pic

Hopefully, we can get this afloat but it's mostly just a feeler for now.


TonyP: 90L
Romer: 90L

+$70 to get double the capacity?!? sign me up for the monster pls.

if the group gets a better deal if i go in for the 90L too; i'll consider it instead

The 90L would double capacity to about 47 gallons (OEM 24gal plus Aux 23gal).

The big one would basically triple the fuel capacity to about 72 gallons which will be about $190 to fill up Keep in mind thats about 450# in fuel plus the aux tank itself

I meant that the 90l is $1,690 so for $70 more you can get 180l. Spend $1690 for the first 90l and then only need to spend $70 more to get the next 90; double the capacity for $70

I hear you on the weight though, it would just be nice to not have to stop when leaving Houston until I get to Midland or Amarillo or OKC depending on where I am going.

Ah! Ok I see what you're saying, yeah pretty much.

I'll make an actual thread about the possible groupbuy later today.

Anyone consider this one:

122L Fuel 55L Water – Auxiliary Combination Fuel And Water Tank | The Long Ranger

That's 32 gallons of fuel and 14.5 gallons of water. Gas weighs ~6#/gal whereas water weights ~8#/gal. So 200# in fuel, plus another 140# in water, plus the tank weight. Not sure the tank weight but it's 145# shipping weight (packaged), so figure about 450# total - 500# if you get the heavy duty version with the skid plate. That said I suspect most people wouldn't fill the water tank unless you were camping, so practically speaking it's more like 300-350# except when you overland.

To me the perfect version would be about 80-90L for fuel plus another another 40-50L for water, preferably with the water tank located closest to the bumper, with a skid mounted between the frame rails. I think that could be small enough to fit under the frame and be protected, large enough to be useful, not obscenely heavy, and useful in a variety of situations.

Then again the 90L might be perfect if I could figure out a way to mount a water tank under the front quarter panel. I know @cruiseroutfit sells a Helton kit but I don't think Kurt has a bladder, just the heat exchanger and tubing.

That hangs much lower than what I would want, personally.
My exhaust is thrashed from dragging and ramming into my frame rails as it is and that would hang lower than the exhaust, from the looks of the CAD pic.

I think storing water in a hard-mounted tank would be more trouble than it's worth for an off-road rig.
The flexibility of using 5 Gal cans seems worth it to me.
Fiddling with water cans is ok with me. Fiddling with gas cans, trying to pour/syphon into my main and potentially getting douched in fuel... nope.

But if you want that one I can ask Dave.

Not integrating the auxiliary tank with the existing fuel storage and merely plumbing a fuel transfer pump solves the EVAP issue and the DOT legality issue. You would have to stop and manually transfer fuel to your main tank. Since I focus on the lack of fuel away from civilization that is a minor problem. As for stopping periodically on the highway for fuel---that, for me, is a blessing safety-wise. Weight is the elephant in the room with the ideal seeking to keep it high for clearance, keep it low for COG, and keep it between the axle lines. Tricky. I agree with TonyP that pouring out of Rotapax's sounds easier than it sometimes is.

Stupid question - does the 90L shoehorn above the stock spare tire mount? From the videos on the website, it appears so, but was just seeking confirmation as I don't have a rear bumper swingout for the spare. (What about the larger tank?)

SQ Part deux - if shoehorned between the spare tire hanger and the rear cargo floor, any known interference from drawer (ARB, Dobinson, Frontrunner, Titan, TrekBoxx, etc.) installation points that would be coming in from above the spare tank?

Edit - just read your group buy thread and seems only the 70L option retains stock spare tire mount, the 90L and 180L would require spare tire relocation, i.e. rear bumper swingout.

They also provide an additional carbon can for the aux tank. I think using both the OEM and aftermarket can at the same time might help even more.

The kit includes a solid-state transfer pump that's manually switched vs the gravity feed tanks from other sellers. I think that'll alleviate some issues as well.

Here's the feeler thread.

That's an interesting question. I don't think it'll cause any issues, but that's speculation.

I'm too far away from an aux tank right now. I need to relocate my spare, which means a rear bumper first. I'm interested in what you guys end up doing though. I already catch crap for the slight rub at full lock I get with oversized tires so whatever I do needs to work cleanly because if it starts throwing codes I'll never hear the end of it form my wife
