Ok,
1. Vacuum pump ois 25-26 lbs.

2. While I didn't do that, I did leak down test the rest of the car, like the doors etc... and replaced the check valves under the hood. The car held tight and the check valves appear to be working. However, I couldn't get anything on the climate control side so a leak is certain.

3. Good idea, haven't done that yet.

4. Good idea also. I checked a few but I need to go through it again.

Thanks, for the tips. As soon as time permits, I'll dive in there and see what I can do. I still need to find out where these two rather short pneumatic hoses, one black they other white, go to. I accidentally pulled them out of that port by the firewall when I was reconnecting all that damaged hose. I'll just do it all at once.

Thanks again,

Frank.
