I've had a few issues with things not working and it looks like most of the items are vacuum controlled. On a whim I decided to check the vacuum, sure enough, i'm at 9 in. Hg. It's steady, no bouncing, but it's below the 15-20 per the manual.



Before I rebuild the pump, are there any common vacuum leak areas I should check? I have a few of the vacuum-hose-to-accessory rubbers I'm replacing (like this) but want to know where else to look. Thanks.
