I'm in the middle of replacing the infamous fuel tank breather apparatus and
I need some help.  I have replaced all the tubing with fresh 3/16" ID
tubing.  The tubes I took off had metal clips/clamps holding them onto the
plastic lines, and also to the breather.  However, neither Bentley nor ETKA
show this clip.  The tubing is a very tight fit onto the plastic tubes and
nipples, so I'm wondering if I really need clamps like those.  The store
only had clamps for 1/4" ID tubing, not 3/16".  Do I really need those
clamps?  Appreciate any help anyone can quickly give.  Thanks!
