Good subject for discussion. I keep my jerry cans on the back of my Jeep. I fill them if I expect to need gas for a given leg of a trip. I empty them as soon as I can because I don't care for that extra weight on the back of the Jeep--I'm already tail heavy enough. One inspection I do is every time before I light my stove, which is within a couple feet of the cans, is to check each can to ensure there hasn't been any seepage or leakage. I also remove the cans from the rack and place on the ground when filling at the gas station, but do leave them on the rack and use a siphon hose when transferring fuel to the Jeep's gas tank.

One interesting side story: During Desert Storm I flew on the Airborne Battlefield Command and Control Center EC-130E aircraft. This story wasn't from one of my missions, but another crew's. They landed at Riyadh, and the first person off the aircraft (which was the crew position I flew also) handed the chocks to the crew chief on the ground. That person wasn't quite off the aircraft when their hands touched (he would have been wearing flight gloves, BTW). A spark jumped between their hands, passing through the crewmember's headset and knocking him out of the aircraft, to the ground, and unconscious. The aircraft had been grounded by the crew chief immediately on stopping, but the ground in Saudi is so dry that it works very poorly to ground aircraft. We spent a lot of time pumping salt water under the aircraft trying to make it a better conductor for the grounding posts, but sometimes it didn't work. Anyway, crewmember recovered and was back flying pretty quickly, but all of us were wary about that in the future and pretty much took to throwing the chocks out of the airplane, then jumping off the steps to the ground to avoid contact between both. LOL.

Next story: The time we landed right in the middle of a Scud attack. ;-)

 

That's interesting.
I guess that leading a heavy duty grounding strip, from the base water pipe system (or power system) to the docking area, was impractical.

 

Each parking spot had a couple 20 foot copper rods driven straight into the ground to serve as grounding points.

 

Thanks for sharing the story mark. Things like that really interest me. Have you seen the titan fuel tank for the back of the jeep. Very AEV'sih in design, nice tucked away and works with the stock carrier. It carries 12 gallons of gas, so apporx 1/2 a tank by my brain calc. But would be great for generator etc as well.

 

No I haven't.

 

your having to jump to avoid getting zapped is pretty smart one . sSame as if you were working on a excavator in trenches and got hung up in elec . lines for some reason or another. The operator should never put a foot on the ground while holding on to the equipment , it makes them the grounding conductor and the path with least resistance to ground . Really should stay in the vehicle . Same holds true with a car in storms with wires down on the street ( stay in the car its isolated by the tires) and could be energized with voltage . Getting back to the orig question, So you do carry the cans empty for some time in the summer temps with out incident ? Even after there was fuel in the cans at other times leaving a fuem in them so to speak ?
Here in nh the temps are not that high but just the same i wanted to know if i can have the cans on the back with out having them turn into a balloon of pressure . Personally i think some people are over thinking this issue as some have said that a motorcycle has a low tank of gas and dosent blow up with built pressure when pulling into the gas station, wich makes sence to me . As you said you dont want leaking cans or seeping where it could ignite. i would think the jerry can being empty would be safer than a jerry can with a 1/4 of fuel in it ?

The side mount looks rather cool but , im a bit concerned being that close to the drivers door and being subject to impact on daily driving and being near a already hot engine could be of concern . So im thinking in the back is prob less prone to a incident .

Have you ever had a can build any pressure ?when its empty ? when the jeep is parked in sunlight .




* Guess this is how they ground them ( in pic) EC-130E not so sure same method

 

The cans do bulge out a bit when it's hot, but not that much. Ever look in the back of the truck for guys doing yard maintenance? Usually several cans in various states of full. Hundreds of the guys out everyday, all day during grass season. Ever hear of a single one having a problem? Neither have I.

 

i figured its a lot of hot air So i figured id ask your opinion on it . seeing your jerry cans seem to be on the vehicle most always in variable conditions , & i assumed variable levels at times . mine would get used but empty
most of the time id imagine

Thanks for the reply

 

I used to crew CH-53D's and UH-1N's. The 53s generate a substantial amount of static electricity in a hover, under the right conditions. Grounding the sling is a must and that "sherpard's hook" is how it's done.

 

Should check it out. very nice tank, and almost unnoticeable when installed. It is on my MUST haves list.
