    I have seen the new ones (push button and twist to open), but I've heard they all develop leaks after a little bit.

    I'm thinking about making a replica of the old Sigg one(pictured below and not mine). A cap, drill a couple holes and add a chunk of tubing... seams pretty simple.

    My question is what kind of tubing will hold up to Coleman fuel? Would vinyl tubing hold up? How about ice maker/water line plastic tubing? Or RC car fuel line, it's silicone, but it handles nitro fuel, would it hold up to Coleman fuel?

    Thanks,
    Sean

    An old Sigg cap, a couple cents in polyethylene tubing, and about 10 minutes of work. This is the resulting pour spout.

    I can make the fuel spout longer if need be, just cut another section of tubing and wedge it in the hole. Now I guess I need to find out if polyethylene will withstand Coleman fuel...

    Answered my own question. PE will hold up to fuel, Gas cans are made of High Density PD(HDPE) so it should work fine. I may make the tube a little longer, but it's compression fit, so that shouldn't be an issue.

    That was quick. Looks good.

    The MSR caps with the little holes just below the gasket work pretty good for small refueling jobs or priming. Unscrew the cap a turn and pour (or dribble), it's not perfect but you don't have to carry anything extra.

    I have a couple of nicer pour caps around. I run into them when I don't need them, and can't find em when I do.

    Thanks. I got to thinking while I was at work and one thing led to the next... I had the parts rounded up and the cap modified. If you look, the Sigg cap has those holes too, just under the seal in the threads. The dribble from around the threads and the lack of flow control made me ditch that as a good way to fill anything I have.

    I will be using this spout primarily for fueling my Coleman 508 and Coleman lantern. I dislike the funnel technique, because I always overfill. This just seemed to make more sense. I'll keep the funnel around to fill bottles from the Coleman can, but this should make filling everything else easier.

    I also plan on getting a Svea 123 soon. This spout will make filling that easier also.

    Warlock, now you need to tie a lanyard to this cap and the other cap, attaching it to the bottle, or it will be lost, when you need it.

    I do use the MSR caps holes, as Itchy said, they work fine for me. Do the new bottle caps have those?
    I also have some bottles with the after market pour spout that can be shut off. I like those, too.

    The lanyard is this next step, probably this evening.

    I have a new Primus bottle that came with my Omnilite TI, it's a "safety" cap... so no it doesn't have those holes. I'm not sure about the new expiditon
    caps. I'll have to look next time I'm shopping.

    Hi,

    Years ago, there was a device which was a simple red plastic ring with a spout. To use it, you took off the standard Sigg or MSR cap, slid it up the threads, aligned the two holes in the cap with the two in the device, screwed the cap back on, and poured. It worked better than anything else I've ever tried. Tied to the cap with a string, it was always available.

    I haven't seen them for sale in forever, but here's a really bad phone picture of one on an old MSR cap. It's nearly impossible to see, but there's a vent hole opposite the pour spout:

    Once upon a time Doc Mark talked about what I think might have been the same device. If so, perhaps he's got an idea if they're still around or someone's got a secret stash of them!

    I've seen mention of those as well. That red ring would have been my first choice, but they seem to be impossible to find now. The modified Sigg cap was easier to manufacture than trying to make one of these little rings.

    Just wanted to complete the visual with a picture of my Sigg fuel bottle:

    For a classic camp stove I prefer something like this:

    Snwcmpr, it's 3 1/2" tall. For filling the priming cup.

    That’s a great idea @Mohoganogan now I just need to find a 3D printer to use...
