If you have someone else runs the test, make sure to find out exactly how many psi it loses and in how many seconds/minutes. Don't come back here and say "yea it passed" and not have the specifics lol :)

I meant the head of the fuel pump.. so that insite I bought is how I do the leak down test? I watched Rawls leak down video and been calling around for that tester..

Yea insite runs the test. What tester are you trying to find? You might have watched the leakdown test video for the 870/871, those engines use a bubble tester, you don't need that. all you need is insite, Rawze made a video of how to do the test for the common rail engines (cm2250 and newer) here it is.....
