Found this on FG (thread was 3 yr old):
How does this compare to the aerotrend Easy-Flex (that isn't carried anymore apparently)?

Re: gas tubing
Aerotrend fuel line hasn't been made for many years - and it probably won't be made again. It isn't just the lack of sales that halted production - it also had something to do with environmental regulations.
Neoprene is OK - but it will get hard fairly quickly.
Ethanol is really the problem when it comes to gas fuel line - some of the line can't handle Ethanol very well. Many of the fuel lines on the market were never intended to be used with Ethanol.
Regarding fuel line size:
1/8" line is fine for gassers up to 150cc.
You can also use 3/32" line for gassers smaller than ~50cc.
We've tested many gas fuel lines - and this is what we found:
Use VITON inside your tank (it will last the longest - many years) - we have it in stock here: http://www.thunderboltrc.com/index.p...roducts_id=669
An alternative for inside your tank is BUNA-N line - this is better than Tygon, but not as good as VITON. You can find it here: http://www.thunderboltrc.com/index.p...roducts_id=668
Use Tygon outside of your tank - we have found that Tygon will stay flexible for a long period of time if fuel is only running through it - it hardens up quickly when it is submerged in fuel (i.e. being used as a clunk line). It is also transparent, so you can see fuel flow. You can find it here: http://www.thunderboltrc.com/index.p...roducts_id=349
