i honestly dont know what you guys over there in the usa have as choices for gas fuel line. yes there are several different types/brands of tygon. and unfortunately you cant tell which one will not go hard unless you "buy and try". as ive said before precision aerobatics have the really good tygon fuel line. this comes standard with their deluxe smoke system which i have fitted to my extra 300. its great fuel line...stays soft and is clear so you can see inside. the price is $1.85 per foot us price. the part number is ac-1619....check it out and yes they do supply to the usa via a company called troy built i think.

yeah i know all you tight arses will winge about "being sooo expensive"....but so are our large models to buy and setup. im glad i spent the extra few cents to get fuel line that will work and never have to worry about again.

cheers
