Hi
I figured if you have a 5% leak at 10 Joints you would have 50%
leakage. So I just check all hose connectors from one end to another.
If the hose slips off really easy then I use a hose clamp or just
replace it from end to end. The Braided cloth covered hoses that VW
loved to use was the biggest leaker. The hose would crack under the
cloth braid and let air in even with a hose clamp. sometimes you can
just cut the hose back a bit and put back on. But you can also spray
with a water bottle but if you find one there are usually 10 others
to play with. Just check them all and dont stop till your done.
Good luck. Remember every fix you do before you go on a trip is one
less you will do during the trip.
