To catch up this mornings work.

Using the 03 as a test I disconnected the check valve at the intake and put the gauge in the hole. Got 14hg. Doing the exact same thing on the 00 I get 8hg. This is using the mity vac pump which has a gauge on it, that might not be all that accurate, but at least it does show how much of a difference there is at idle between the 2 doing the exact same results.

The 03 has ZERO issues and runs wonderful so I know that it is good to compare against.
