Fuel line Impulse line Tygon 1100 1200 1300 4040 True Blue Echo

I'm not up on all this different fuel line stuff. So is this
Tygon LP 1200 going to be a line to handle ethanol? Any other
info on subject.
[QUOTE=Merle Nelson] Just learned that Tygon will be coming out
with another fuel line hopefully in March after EPA hurdles
(Tygon LP1200.)
I use it for the old Poulan 25 variants. Tygon 4040A fails in 5
months or so, LP 1100 which I just got a role of is supposed to
“de-laminate” and cause problems when changing out fuel filters
after a time. It’s a bit stiff too. LP 1200 is supposed to be
the wonder child. Or so says the tech guy I talked to.[/QUOTE]

The 4040A like what you have in stock and what they sell at
Glenns has been the best for gasoline so far

Cut4fun invited me on and to post on the thread - Thanks!
The Tech guy I talked to on the phone who told me about LP1200
asked what I was using now. I said well, Tygon 4040A, I was
told it was the best so I bought a roll. He said actually it’s
not intended for that application (submerged in gasoline). I
said ahhh... someone should get the word out then cause that’s
what all the shops and people I know are using (on old 25DAs
anyway.)
So I had already ordered a roll of LP1100 from a supplier-US
Plastics. It is supposed to be ok with up to 100% ethanol.
That it is a laminate leads me to suspect that it is not
supposed to sit in gas all the time either - though I did not
ask the tech guy from the factory this question. Feels a little
stiff to me for following the gas around inside a 25DA tank but,
I think it will work.
I’m looking forward to LP1200 and hoping it will be a one time
answer. In the mean time I trust that the LP1100 will be far
better than replacing 4040A every so many months and smelling
raw gas through the day as the indicator that my fuel line has
shrunk and hardened.
If anyone has wanted to try LP1100 and give knowledgable input
to the rest, I would send a length out to the first couple of
posters/PMrs. ( 3/32 ID, 3/16 OD 3/64 Wall thickness) Length of
line? Mailing info.?

I've had bad luck with Tygon swelling when submerged in fuel
tanks, works ok if the fuel pick up is zip tied or safety wired
in place otherwise it swells the filter falls off. Some of the
synthetic rubber hose tolerates methanol laced gas pretty Well.

Gas AND methanol seems to be the issue. Either or is easier to
deal with. I'd imagine PTFE line is gonna be the most gas/alky
tolerant but it has its own issues related to flexibility and
securing it to barb type connectors in saws

My experience years ago (50's) with clear vinyl tubing was when
exposed to methanol and nitro, The tubing would turn milky and
hard as a rock within a month.

Two new lines installed today. Both are in Poulan S25DA and
S25AV’s, so some of the line is submerged in the tank and some
will only have fuel contacting the inside liner.

Do you guys work on a lot of the poulan s25? If anyone has a
nice clean one for sale, I'd love to buy one! great Saw! Used
one for climbing/tree pruning in the day til I bought an O20l.
