manifold pressure tubing type - FWF

[Scott Will]

What type of tubing is used for the manifold pressure lines ahead of the firewall? My lightspeed is mounted there and wondering if the stuff they give you is OK (looks like radio control aircraft fuel line tubing)? Whatever it is, I need to have a tee to go behind the firewall to the EIS 4000 MP sensor.

Thanks for your help.

Is it the blue tygon tubing? That stuff is pretty tough and is fine FWF.
