Cant believe video doesn't have positive comments. This is excellent video as there are NO other Econoline 6.0 pressure test videos. I'm doing pre-purchase testing of 2005, E450, 6.0, class C motorhome. None of other videos on pickups show the 2nd step of relieving pressure from degas bottle and continuing test. Eliminating a false positive high pressure due to warm up expansion of cooling system. Plus it shows the essential data fields that need to be watched during test. Everyone says check... But only a few say which fields to check. This unit must have the fuel pressure spring upgrade, judging by fuel pressure??? Lots of videos on engines with problems, but none on good engine to compare to. Thanks for posting video, probably the best 6.0 video on YT.
