How often does your secondary throttle vacuum pump come on w key ON?
My vacuum pump runs for literally 1 second then shuts off. The system appears to be pretty tight as far as that goes. It doesn't seem to leak from that aspect. Everything was ZIP-Tied and and any pieces that didn't seal well with a vacuum pump were replaced.

I have leaking fuel from under my plenum. It didn't do this the night I got the work complete, and it didn't leak yesterday. It must have done this overnight. So I guess the plenum is coming back off?
