no offence taken bfxr6t, even if you were hehe

my mind has a habbit of running off on me when i'm trying to explain something and i get a bit hard to understand sometimes lol

yes i had to make a vacum tank for a truck the other day coincedently, got me wondering what they use vacum for ? and ultimately was it from manifold vacum or pump ?

I relise there are diesel engine ford in still running that have a vac pump, man i've worked on more diesels, and petrol engines for that matter than you have had hot meals, the thing is i WAS NOT talking about diesels, the subject is the Ford I6 incase you haven't noticed.

My point is completly on experience, i had built turbo, supercharged, and hard tuned natmo engines, most of which have had a vac gauge. I have tried in experimentation fitting gauges from the brake line, and it does not work properly, not an accurate reading, as old mate even tried and stated as i already mentioned. The same applies for boost gauges and controllers etc, its not a vac line desinged to run such stuff, hence like i said, no manufacturer that has vac gauges fitted factory run them from such a line.

I'm hardly interested in reading said link, as i have practical evidence of it not working.

End. I think this thread has run its course.
