RotopaX RX-SP-Vent Self-Venting Spout Kit

I do a lot of Jeeping and sometimes those trips are multi day long trips. I purchased a rotopax to carry some extra fuel, but the stock filler nozzle that comes with them are horrible. This is the perfect replacement nozzle. While it says it is for water, it works perfect for gas also. I used it twice in the last month and it pours the gas into the Jeep perfectly. Pours fast with no leakage. If you have a rotopax, you need this to replace the horribly designed spout that comes with them.

This spout is absolutely awesome compared to those modern eco-spouts. I purchased this for my Kolpin Fuel Pack. To be honest, it's not a perfect fit because the seal is slightly smaller in diameter than the original spout which means that it can become off center when I am tightening down the threaded cap. However, if I am just careful about it I have no trouble centering it up & tightening the cap down so it does not leak. But, what do you expect when it's designed for a different brand right?... The reason I bought it is because the original cap for the Kolpin model has this red cover made of VERY thin plastic that will obviously puncture if anything ever bumps it. This replacement spout has a yellow plug that is much more heavy duty & I have a lot more faith that it won't ever fail out on the trail & leak my gas all over the place. The fact that this spout is also flexible, self venting, & not one of those pain in the butt eco-spouts is also a great feature.

works great, very fast filling

I used the gas can fuel spout on an expedition with my motorcycle and found the original spout very difficult to use in that application. This spout is much easier to pour. However, with changing elevations, the spout did leak at the cap. In retrospect, perhaps swapping out the gaskets from the original fuel spout might have prevented that, but I cannot say for certain. I did not lose enough fuel to be a hazard, but it did discolor the plastic on my water Rotopax. If you're going to swap it - keep an eye on it. My water Rotopax uses this spout and it worked flawlessly the entire trip. YMMV.

Way better than the rotopax spout. Actually usable

Considering this is rotopax and I have a rotopax can, it should've fit. It was way too long. I just cut it to the same length as the one that came with the can. At least it gets rid of the ridiculous one that came with the can.

Fits the fuel pax but can't be stored inside the tank. Pours much faster and with less spillage than the CARB approved nozzle

Replaced that government designed nightmare that I was never able to get to work. When returning from the evacuation of Irma last year, we luckily brought 15 gallons of gas just in case. Got about 150 miles from home and no gas at any station. So, I resorted to my gas cans. Let me tell you, those spring loaded pieces of crap got more gas on the car, on me, and the ground than in the tank. I ended up fashioning a funnel out of some cardboard and just dumped the gas in. That worked better than the spring loaded death trap and it got us home. This simple nozzle would have been a lifesaver. I tested it out today just to see, and not a drop anywhere but in the tank. Government could flub up a one car funeral.
