Default Fuel line recommendation

Hey, all. What kind of fuel line are you using and where did you get it? btw, not even sure the ID we need to use, anyone know? I've had the last two turn milky, harden, and get shorter on me. Thinking about this one... https://smile.amazon.com/dp/B000WK3L40

btw, I have this kit. http://www.gasbike.net/collections/2...cle-engine-kit

Tygon, available at most lawnmower shops. Get the size smaller than you think you need and it fits real nice.

Take your fuel filter with you to the auto store and get some black fuel hose for cars. It works great and will last a long time.

I use moose brand available on eBay, the solid black ones bother me as I can't be assured of fuel flow. Moose brand is crystal clear, cheap and is as tough as nails and will outlast me
By a hundred years or so. Love this stuff.

If you're worried about fuel flow just get a clear fuel filter. I have a clear steel mesh type filter and as long I can see fuel getting to the filter then cool. You can also just pull the line and open the petcock to see the flow. If it's designed for a car then it's good for our mb's.

Yep, the black stuff is good and is cotton reinforced too. However what if the fuel filter is clogged and not flowing all the way through , I hate to be pulling my line off all the time, if my bike wont start to eliminate fuel flow probs. I just prefer the crystal clear line. Either one is fine for sure. Just a personal choice, but for sure the semi clear milky stuff in the kit hardens and can crack and that's not a good thing. The rubber line turns my fingers black telling me its not a good quality rubber that can also deteriorate from ethanol gas...the rubber type also has a thicker wall also and probably less likely to kink though.

I actually wanted to use steel braided fuel line and still might one day. I know very expensive but would look awesome. Either way I think a straw is better than the kit supplied line. I think even at the auto store they have fuel line with the lawn mower stuff that I think would be fine

I was feeling detail-oriented when I was putting together ol' Tempus. I splurged a bit on copper tubing and compression fittings. But I made sure it had a bigger ID than the original plastic line, and I suspected the bogging issue I was having might be because the engine at WOT could use gas faster than the original line could supply it. I turned out to be right; the larger-ID of the copper line solved that problem. However, every engine is different, and some don't behave that way. That, and I've done a bit of "souping up". Where most of these little 2-smokers will get kinda close to the 150 mpg mark, I am likely only getting about 120 mpg, although when I turn the throttle, Tempus GOES! RIGHT NOW! No more bogging or any hesitation. I got me near-instant throttle response, and I'm pretty pleased with it.
But if you use copper, there'll be some customization involved. And you'll need to make a couple turns of coil in the middle to take the vibration of the engine, so the line doesn't work loose from the non-vibrating tank. I have pictures of it in my album.
Keep in mind: unless you're going for a vintage look, or something steampunk-like, regular rubber automotive-grade fuel line will work just fine, as well as some of the other stuff that the previous forum members have mentioned. Good luck.

When I was setting up my 4 stroke Honda 120 on a Huffy 26" 10 speed frame, I just rigged fishtank tubing, as the stock line on that free to me motor(from an old golf green mower) was the same size, but old & frail.
Now that I have the bugs worked out of the gear ratios, I'll enclose it in flexible electrical conduit.
Unless you're going to trek across the Gobi desert, or enter yours in a fancy judged show, just use whatever you can find, near the same size. And don't smoke while tinkering there....

I use that black rubber reinforced type that says Gasoline and some code type on it, but my pleated paper fuel filter is in a clear see through construction. I can see gas in and also the flow of gas just when I open the fuel valve initially if prior ran the bowl dry. It works for me fine.
