That's not the MOST unkind thing that's been said about the shape of the nozzle to this point...

You keep laughin' there, Phil - right up to the point that you see the business end of that thing coming at you in the side mirror at Summit.

Kirk,

Could you post pics/list of the parts you used and where you aquired them? What are you using for the vent hose connector? I'm assuming you cut a hole in the gas can and used some kind of threaded adaptor with a gasket. Then an elbow with the hose clamped. Beats the hell out of buying a expensive dump canister.

The key part is a 3/4 NPT poly "tank fitting" by Banjo Corp. You'll need to find a local dealer (try the Banjo web site) - mine was an agricultural fertilizer company.

They are supposed to make one with a Buna-N fuel-resistant gasket, but I couldn't find them locally and ended up with Viton seals which should be fine.

The rest of the parts are poly NPT-barb fittings from Home Despot.

Nice setup,

Just some free info,

I drill out the vent breather with a 3/8" drill bit on all my gas cans. By doing this, they will dump much faster too.

Nice setup Kirk! So that tube on the bottom is just a big vent?

so then what do you use to cap the bigger hole? Is it still small enough to fit under the cap that it comes with?

It works exactly like Big Boy dump cans. That tube is just a vent, the same size as the fuel outflow and on top of the column of fuel rather than at the bottom. You turn it over and no glugging or bubbling - the fuel just drains.

Kirk,

I don’t know if it would work for you, but I recently timed how long it takes me to dump 5 gallons (of diesel) through the “standard issue” US Army Fuel can using the available “nozzle” (Donkey D**K in military terms) that locks on the can. and it was about 30-35 seconds. These parts are all available at any Army/Navy surplus store and the new cans are plastic, not metal.

Now obviously this vehicle has no unleaded restrictor and I don’t know anything about how much better or worse diesel would flow than gasoline but I thought that 30-35 seconds was impressive.

Just a casual observation at work this week. (Yea I can’t wait to get back on the track)

Kirk,

Years ago, when I first got involved in endurance racing (Entropy Racing), the team owner, Charlie Greenhouse, had something that looked almost exactly like that. They worked very well. I've seen others that have ball valves on both the fill and vent lines, which lets you store fuel in them. Also, since none of the cars we ran were still street legal, we removed the restrictor from the filler neck, which allowed for a larger fill hose. I don't remember the exact fill time, but I believe it was on the order of 30 seconds.

NASA enduro rules limit you to 2 5 gallon containers. Those were advertised at holding 6+ gallons, in addition to pouring faster. Jerry Kunzman declared them illegal following last year's 25 hour event. I can't find a refrence ot it in the rule book though...

There's a reason why I pay to be on this site! I was just going to buy four of those jugs for my "enduro" car that I'm planning on running at the 25 hour. The Acura team put those jugs to good use last year. Marcus I owe you a beer.

That's a little goofy. There isn't a "5-gallon fuel jug" out there that can't hold more than that, if you fill it right to the hose.

At the VIR 3.5 hour, I actually filled them only to the 5 mark - primarily so I knew precisely how much fuel went in - so it kind of seems to me that the rule should be more about the amount of juice in the can, than about how much will fit.

John- I'll take you up on that next time I'm down south http://ITForum.ImprovedTouring.com/smile.gif
The Acura team did put them to good use. Somewhere on the web is a picture of Off Camber's setup; its worked realy well also. I'm looking for it now.

Kirk, the reasoning is that these are advertised to hold 6 gallons, and its known they pour faster than than a normal can. Jerry elected simply to not approve them for use. Its a cost svings for everyone that already has decent cans.

Marcus,

What I hear you saying is that NASA won't allow cans that flow faster than some established flow rate. Not sure if I understand why. Not sure about NASA, but I know that some of the endurance races I've been involved with, put a min. time limit on pit stops where you take fuel. IIRC, it was something like 1:30 at the Moroso 24 hr race. I'll have to check the supps for the Summit Point race.

I'm also not sure if I like the idea of one person being able to deem something illegal.

Yeah - I understand. I'm just not buying it.

If I re-engineer my "decent cans" to pour faster (I would, if I didn't have the unleaded restrictor being the limiting factor at this point), would they be illegal?

If the jugs in question were exactly the size that they are but had never been advertised as "holding more than 6 gallons," would they be legal at this point in time?

Marcus. That Off Camber set up looks interesting. What do you know about it? Where does that extra pipe go to?

Marcus Miller
04-14-2005, 10:12 PM
Bill, Kirk really hit the nail on the head. They are advertised to to hold 6 gallons. NASA's rule limits a team to 10 gallons of fule in hot pit any given time.
We all know most five gallon cans can hold more, that's not really a secret. Coupling the fact that these are the fastest flowing, and they advertise the 6 gallon limit was enough for Jerry to call foul.

Kirk, lots of guys modify their "std." cans, bigger vents, relocated vents, etc. unless you get outrageous, no one is going to say much. I believe the answer to your question would be that if there was no advertising, they would be legal. That is of course my own WAG....

The details are fuzzy, and I can't find their explanation of it. I think the 2nd pipe ran back up through the cap, and was long enough to reach the bottom of the jug. When the tank was full, the vent hose would fill the tip with fuel and stop the jug from dumping as the pressure (?) equalized. I'll look around and see if I have their real explanation.

Marcus,

First, I doubt they're the "fastest flowing", but that doesn't really matter. And by the logic that you state, I could take my 8 gallon cans, advertise them at 5 gallons, and as long they didn't flow to fast, they'd probably be legal.

I'm botherered by being subject to some arbitrary flow value (or more accurately, someone's arbitrary perception of what is "too fast").

You want to make sure that people don't have more than 10 gal. of fuel (I assume there's also a size limit on the container, nothing larger than 5 gal.) in the hot pits? Put it in the supps that random checks of fuel jugs will be conducted. Any jug found to contain more than the allowed max (e.g. 5 gallons) will be confiscated, and the team will be assessed a 1 lap penalty for each infraction. And if it means a team loses all their fuel jugs, oh well, it was in the supps, and they should have known before they came. Non-complaint containers will be returned at the end of the event.
