Vacuum line

[DemonGT]

Got the supplied vacuum line ran through the firewall of my 91 mustang and was going to install it on the factory vacuum tree on the drivers side firewall since i had a open
spot but the hose is to small to fit over it? What size fitting to i need for the vacuum line? I have the upper intake off to fix some unrelated issues and figured id install
a fitting just for the Pimpxs since its off.

Hose size depends on ECU version number. Should be 1/8" or 3/16" depending on version number. If the MAP port on the ECU is on the side it's 3/16", if it's on the end with the EEC connector then it's 1/8". Can use a vacuum line adapter fitting to connect it to the vacuum tree port you have available as well.
