Libby found a great supplier of Clear Fuel Grade Tygon (friendly prices) a while back.
I had bookmarked the thread - and its gone.
Guess he originated the thread - and it went with him.
Seems like it was in Arizona.
Car Masters / Auto Masters / McCarMasters AutoMcMasters ..... or something like that. They had a website.
Some of it you had to buy certain footage.
I bought into some with him on the injector return hose size.
VERY VERY TOP NOTCH.
But i don't have much left of it anymore.
==========================
I had been using translucent yellow tygon on injector returns, purchased from small engine repair shop locally. The clear from Libby's place seems even higher grade - and its clear. And it was less expensive too.
Meant to place an order for fuel supply/return sizes and never got around to it. Libby bought those sizes and had use for the amount ordered. He loved the stuff too. So its good.
Been using cheap clear tubing from Tractor Supply / Lowes Hardware on fuel supply & return on several cars. Some of it is going on 3 years and it gets rather stiff in Winter now. In case anyone is reading - it won't suffice on injector returns - but does well enough on larger hoses.
Later or sooner, i want to get on the ball and refind that supplier and get the better stuff.
