Pretty cool. I think today I’ll cut another vacuum tube at maybe five or six inches and see if that’s any different than my 8” tube. I don’t expect to see a difference though. Ill refuel and see what I’ve gotten with the 8” tube and compare it to the new tube.
If your brake booster vacuum tube is 15” and you have a 4.7L engine, that’s 3.19” per liter of vacuum tube. 3.19”x my 1.6L engine is 5.1”, so I think I’ll try something like that.
