Vacuum test

any ideas?

I want to do a quick test to see if i have any vacuum leaks, and am thinking that if i connect my vacuum tested to the pipe that runs to the airbox, it would test the whole system.

no the pipe that connects to the airbox is the opposite to the one you want to test as that pipe is just supplying fresh filtered air. You need to be teed off on the suction side. Maybe you could put your vacuum tester on the end that goes to the vacuum reservoir
