Are there any tips for removing fuel line that doesn’t want to come off the fuel tank or carburetor?
It seems like I always have to resort to cutting it off both ends with a razor blade. Surely somebody has a good trick or tool suggestion?
Over the course of time, I’ve tried flathead screwdrivers, o-ring picks, pliers, and pulling with my hands. I always pre-lube the fittings with premix to make them easier to go on.
It’s not a big deal to cut them off, but I just like learning and improving.
Some fuel line is more susceptible to this problem, but running ethanon-free fuel makes the most difference. The ten or so percent ethanol content in pump gas degrades some types of rubber much faster than plain-old gasoline.
There is a type of fuel line that the OEM's use that's typically a lot better than what you can find locally.
I see it called "Tygon" at most places that sell it. It's low pressure stuff for carburetor applications only.
I've been running the product linked below from McMaster Carr on my two-strokes for a few years and it stays more flexible for a long time, like the OE Yamaha stuff. I strictly run a 50/50 mix of leaded race gasoline and ethanol-free pump premium with Yamalube 2R. The tubing is a advertised as a "Tygon" rubber blend.

I just went through this earlier this week. I put Tusk fuel line on my 200 and 125 at the same time months ago. The fuel line on the 125 is just as pliable as new, but the 200 is stiff as a board. The 125 gets straight Sunoco 110 and the 200 gets a little 110 and ethanol free 90.
Ethanol free gas in this area is available, but the issue is not enough people buy it, so it very common for the non ethanol gas to be stale. I was running 100LL avgas which did give a little bit of performance gain, but the smell of it makes me feel sick and I ultimately can't be around the fumes for more than 5 or 10 minutes. Just makes it tough to work on a bike when you can't take the fumes, lol.
The E-free gas we have around here has a very strong skunk smell. No kidding, it smells just like when the kids fire up their joints in the pits at the track. And I have noticed it being rather hard on the plastic spouts of my jugs and rubber float bowl o-rings.

There are specialty pliers for that, like below, grab, twist and pull
Ours smells pretty rank too, and ours is always fresh. I live right by the water and multiple boat ramps so I know my area goes through a fair share of E-free. Kinda frustrating to get away from ethanol only to have it trash my fuel lines.
Nice, thanks! I’ll have to pick some of those up.
I use a set of channel locks, with the width smaller than the hose, but bigger than the petcock spout. Grip it and twist off.
Use a hair dryer or heat gun (on low) to warm it up. Don't pull it, twist it first to break the seal, then pull.
