Vacuum line - carb to dist.
I was thinking of replacing my vacuum advance line from my 34PICT3 to
the SVDA dist. and recalled a friend's rock stock 71 bus with the original metal "up and over the float level" line. In understand why VW did this, but here's my question: Is the actual inside diameter of the line critical - not where it hooks up to the dist. or carb, but the actual line ID itself. More specifically, is the vacuum signal to the dist. the same with a 3/64" ID line vs. say a 3/32" ID line? TIA Bill. |

What is the reason for the "up and over the float level" routing of this vacuum line, and is it important? I just used a bit of rubber hose here... Peace, Harry |

VW would not have spent the time on R&D and making and installing a not-needed part........ |

This part is to prevent deterioration of the diaphragm in the vac cannister of the distributor. |
