[urq] Intake pressure tester?

[Jim Fleischer]

Hey guys,

Trying to button up the ur, and need to track down a suspected vacuum leak leading to a hard start, rough initial idle and higher RPM cutout condition.  I thought I had the specs to build a pressure tester, but can't find it, and google is coming up with everything but an urquattro.  Can anyone forward me the list of items and especially the size pvc pipe I need, and maybe a do's and don'ts of this process, such as how much air pressure?  I've seen it done a few times, just don't want to mess anything up.  Thanks!
