Itinerant Air-Cooled

Hi, the metal woven fabric/rubber air line to the booster is frayed and shot at the booster. It looks ok the rest of the way under the wheelwell.
Can someone (me) plumb in a short section towards the booster side (small dia. metal tube + section of new hose), or should the whole thing get replaced?
Where does it go (the hose) as it enters the body near the front wheel? Is there more hose lurking in there somewhere?
Thank you!

That is an important hose. It allows the booster to vent to atmosphere, which is what is actually helping you apply the brakes. There is a filter in the servo pushrod section, a foam filter. It needs the hose to take clean air from the b-pillar cavity. Because the servo pushrod has to be able to move a good deal, especially in a circuit pressure loss, you need a flexible hose from the booster to whatever section is attached to the wheel well.

Why must a hose be routed in such a fashion? Wouldn't a filter at the booster work as well as that longassed hose? Or is it too "dirty" near the booster for clean enuff air? It's wacky.

Perish the thought! VW buses are known for fording streams, jumping puddles, and otherwise completely not allowing a filtered air supply down at road level. Consider this hose a snorkel. Remember what I did to that poor Road Warrior? Cindy does, water up the sliding door, original booster worked flawlessly to the day it died.

Snorkel, I get it now. Thank you!
