88 S4 rigid vacuum line lengths..
 

There was a post that I -swear- I had bookmarked, that laid out how long the rigid vac lines need to be coming off the three TB ports.


Am I foolin myself..did it exist at all?

yes there is one but Roger always printed it out for me. Honestly I think some of the lenghts are a little too long.

I can measure some, but mine are RHD, and at least a few of them are hence different (e.g. brake booster is on the opposite side of the car). If its still any use post here and I'll go measure; they're in a box in the 928 take-off parts cupboard.

I replaced the engine bay ones (i.e. non-HVAC) with 3mm dual-layer silicone/polyester vacuum line, and in the process got rid of the rubber elbows too.

Feedback the lengths if you feel they are to long and we can update the information.
