Boost Guage Line Size
I am having a problem hooking up my guage. I taped into the map sensor line like I was told, put a 1/4 inch tee and ran 1/4 inch line into the cab. Is the 1/4 inch line to big? The guage came with a piece of 1/8 inch line but it was banged up so I thought running the 1/4 inch would be okay. Is a boost guage just read vacum? Because when I hook up the guage it will not read anything, but if I hook up a vacum guage it will show movement. If i blow into the line toward the guage I see movement on the boost guage. I know all this sounds crazy but Did I go wrong with the 1/4 inch line? Also there is a small reducer that goes into the back of the boost guage that has a very small hole in it. Does that need to come out or stay in?

What does the red line do or go to? I tapped a T into the map sensor with a 1/8th line.

I wondered about the tubing size also. I held off hooking up the 1/8 boost line thinking if I go up one size to 3/16 it would have quicker response and less pressure drop through the tubing. I also ordered the plug to replace the IAH and will tap in there.

I bought this kit for my boost gauge - my gauge was used off Craigslist. Bought the tubing also. Plumbed into the map line and works like a champ.
