I routed mine through the same rubber grommet. Avoid sharp turns so you dont kink the line.

Mine is routed through that same rubber grommet for the wiring harness and T'd into the vacuum line for the fuel pressure regulator.

Follow the steering column to the firewall. Should be a rubber boot there. Pretty sure that's where I ran mine.

Yep, it should have an unused rubber tit you
can snip off and pass the line thru to retain
the water tightness of the grommet.
This is a pic of the pass side.
The drivers side is almost identical.

Diabolical!

I used the electric boost gauge. Mounted the sender on the underhood side of the firewall and ran the wires through a rubber grommet up to the pillar gauge.
