I have a ten year old Craftsman blower, big old machine, powerful. Quit running last year, bought a new carb, fuel lines and filter. Running great until today. Pulled out the line, filter came off. Line was split. Putting the filter back on and the line just splits, roll the line between my fingers and it splits. Still looks new, nice and clear. Is this a common thing these days? Is there different qualities in these lines? A type or spec. to look for? I'm kind of lost here. Like to find some fuel line that lasts, if possible.

Are you running ethanol gasoline?

If you are, and can find non-ethanol gas nearby, replace your lines and quit using ethanol. https://www.pure-gas.org/

If you must continue to use ethanol gas, replace your lines and be sure to ask for lines that are compatible with with ethanol.

Generally use BP mid grade gas in everything, probably 10% ethanol I'd guess. Where I live I doubt there is any place that carries pure fuel, especially a fresh supply. Thinking maybe I need to put a larger piece of hose over the main line, put the line of the filter barb, then slide the larger piece over this to reinforce it. That filter seems like a big stretch for the small line. Looked on Amazon and lots of critical replies on this situation. Thanks for your reply! Tom.

You need to buy TYGON ( yellow ) ethanol resistant fuel line from your local lawn equipment dealer, ( I have found it at ACE Hardware stores also ) see attached pic ........

...... it comes in various sizes to suit your needs

And double check the INNER size as the line to the fuel filter is heavy walled while the return line has 1/2 the wall thickness.

The supply line on this engine was a small line, bit over 1/8" OD, the return was a larger line, maybe 3/16. But the line would split if I just rolled it between my fingers. Was the clear yellow line that was listed as a Tygon fuel line kit. I guess it was just my luck, two strokes don't like me very well these days. I was thinking maybe there are different grades of this stuff - best, better, good, and Chinese.

I'm seeing this line described as Tygon 4040, and others as only plastic fuel line or poly(something). I suppose the failed line was the cheapest stuff I could find and maybe not actually the Tygon spec. lines? Should have done some research before buying the cheap stuff. I guess I was right, best, better, good, and Chinese grades - and I bought the last maybe. And these little machines are kind of tough to work on for this deal. Life is just full of lessons.

The splitting of the line at the filter and just coming apart when touched is common including the tygon lines. the new low perm stuff is even worse to split it seems, and doesn't stretch over the filter barbs very well.

A little trick is BEFORE trying to install the smaller Diameter hose's, is to heat the end in boiling water for a minute or so, AND apply a tad bit of Vaseline or grease to the barb fitting it's going onto, works GREAT for me....... Boo

I'll give that a try with new line. Might also shave off some of the larger part of the barb, won't leave along side the road if it comes off anyway.

I am now buying a fair amount of parts direct from various factories in China now that the Sten's wholesaler has gone bust and Oregon has gone over the Briggs & Stratton.
IT is amazing what you see when you start searching for parts.
Tygon is only made by Saint Gobain in the USA
However a lot of Chinese wholesalers list
"plastic tube in popular yellow colour"
And
" plastic tubing printed to your specifications"

We get a lot of knock offs down here and it is fairy common to find them fitted with cellulose / PVC or PVA tubing
These will crumble, shrink or break in a very short time.

It's Saint-Gobain Performance Plastics, not St Germain.

I know you are probably aware of that but others reading this may not be...

Thank you.
Post has been corrected and you are 100% right it is important that information posted on the web is correct.
Brain new what should have been typed but fingers went ferral.

Tried something a little different, will see how it works.

The fuel filter will probably fall off.

I always put the fuel filter on the thicker line and use the thin one for return. Doesn't make any sense the way they set it up from the factory...

Umm, wait minute. That's too easy, and it makes sense. The return line has a restrictor fitting on it anyway so the small line would work fine for that. Now I'm about upset, why didn't I think of that? Always a next time. Thanks for posting!
