[Vwdiesel] 88 jetta turbo diesel-HOSE

Sat Apr 5 15:53:05 EST 2003

This hose everyone is talking about.  Is it a very small diameter hose,
perhaps 1/4"-3/8",(perhaps 9"-10" long) braided outside, and sortof
connected to the top of the injector pump?
Sorry if it seems "simple" (or I seem simple,LOL) It's my first time under
the hood of a diesel, first time seeing a turbo, and only my 2nd VW (first
was a 74 VW back in 1981).  Also, I have no books, docs or manuals on this
beast at all.
Thanks

Mike
