The deal is :
a) its a prick to keep clean but carb clean works well
b) it's a prick to get the clamps on (insulate the end with insulation tape)
c) it's damn expensive! If I remember right? About $65 a foot for 3/8th.
Don't by the cheap stuff it turns to jelly. Norden don't sell the cheap crap. The stuff they sell is made to last. Autobarn buy from Norden. So for the good stuff @ autobarn expect to pay a profit margin.
I've got some in my engine bay for the brake booster and fuel lines running to the fuel bowls.
