[s-cars] missing boost - replacing hoses

[Sean Douglas]

Teddy:

The clamps can be easily cut off, use a pair of wire cutters (end
nippers) to cut off the "ear" of the clamp. Getting a gear clamp this
small doesn't usually work that well. I use the crimp-on style clamps
for this type of work, or if its something that I want to take off
frequently (such as the ECU boost hose, when I was testing chipsets)
then I use a special clamshell-style clamp with a machine screw.
