McMaster Carr's Tygon fuel line
- Thread starter Mikey

(please)
I’m going to soak a piece of the clear Tygon in gasoline for a few weeks and see what happens. Btw the stuff from Aircraft Spruce has all the correct markings.
Can I offer a meek response.? Fruel line is really cheap compared to the hassle of a leak 2 or 3 or 4 years later. Replace it if the last time you had your tank off is two years ago.

Bosco - the place I buy my Tygon from here in Adelaide has some in a jar of petrol, on the front counter, thats supposedly been there for ages - and of course it still looks good. I like the way and how easy it is to bend which allows me to fit the small fuel filters down the inside side of the 38's.

Just checked McMaster Carr's website for the F 4040-A
The industry standard for fuel and lubricant applications, this tubing can be used intermittently with petroleum-based products without becoming hard or brittle. Do not use with ethanol-based gasoline. It is flexible, so it bends easily around objects.
- Clear Tygon formulation SE-200 polyvinyl chloride (PVC) to visually monitor flow
- Fluorinated ethylene propylene (FEP) lining for increased resistance to chemicals, solvents, and alcohols
Compatible Material Air , Beverage , Ethylene Glycol , Food , Hydraulic Oil , Water
I'm just going to use what Tygon that I have and see how well it works
If need be I can always switch to the Tygon SE 200
It must be E10 which I use when on the road not the E15NEVER...NEVER USE E15 IN A MOTORCYCLE
I only had an issue with one batch of tygon an ebay deal it was medical tygon and would swell a bit. I mostly buy Oregon branded fuel line now cuz the local farm store stocks it. It's the usual tygon color. I mostly but not always run non ethanol. With higher prices may use a bit more regular. I had a long chunk of that cheesy eBay line in my riding mower for more than ten years it always got the cheap gas and dregs from drag home barn bikes, that line was still fine and I'd had it on and off several times.
Don't live in Arizona but never had tygon harden. Lot of fuel line gone through here, not kidding, 50-80? Feet? Much of it on bikes I had a long time, rare as that is. I also have one chunk of translucent blue from my powered parachute days has been my drain tanks etc line for many years it's still like new. The vender I got from out of business... Went to find more cuz I liked the look of blue better than the yellow.
There is another grade/type of gas at the pump that you shouldn't buy. Some pumps have 'Unleaded 88' boasting 88 octane instead of 85 or 87 and it's cheaper. This 'Unleaded 88' is actually E15 in disguise. The Feds are trying to fool into using it. DON'T USE IT EITHER...
It is easy to ask yourself why can a little bit of ethanol cause problems. To understand the ethanol problem, looking at the molecular structure answers a lot of questions. Ethanol molecule vs Octane molecule. The smaller molecule can penetrate plastics/ rubbers that gasoline (octane) cannot. I had an early Honda Prelude , 1978 ish, with a plastic carburetor float. The float filled with ethanol. That was a SOB to troubleshoot.
At home we have 4 choices at the pump luckily they are labeled plainly so you can pick the unoxygenated fuel for your small engines but if you are day dreaming theres diesel to chose from among the 3 other grades of gas
One day while daydreaming
I filled my car tank with unoxygenated fuel now that was an expensive fill up
I usually buy yellow Tygon fuel line but saw Aircraft Spruce had some clear line. Bought some and tried it for the first time. I guess I should have researched it more carefully because the clear stuff doesn’t like fuel ( and it said that somewhere in the catalogue) - my bad, not theirs. The line seems to stiffen up when exposed to gasoline, unlike the yellow stuff. They also sell an opaque line that’s fuel rated so I ordered a couple of feet of that today. I can find another use for the clear stuff. Just an fyi
Plastics vs sunlight.........some of the deteriorated fuel lines that I've seen could have very much been caused by direct sunlight instead of the fuel that they transferred. just another variable in this equation, not discussed.
Just received the opaque Tygon from Aircraft Spruce. It’s quite a bit stiffer than the yellow line. Methinks after I use up the opaque stuff I’ll stick with the yellow.
I worked for a very knowledgeable PhD in chemistry. He pointed out that cheap windshield wipers streaked after 6 months because the manufacturer skipped on the antioxidants in the mix. The polymer is cheap, the antioxidant and impact modifier (adds rubbery feel and rubbery properties) ate expensive.
If they sell it as for use on aircraft it would be the real stuff
I used the opaque Tygon (thick) line on Go Kart applications. Almost impossible to remove from barbed fittings and push on filters. It usually had to be cut off with a razor knife. Ended up using the yellow neoprene transparent line. The only problem was if it sat for a week it became hard as a rock.
WTF engine is that? Looks interesting.I used the opaque Tygon (thick) line on Go Kart applications. Almost impossible to remove from barbed fittings and push on filters.
