This is my 2001 Ford Ranger 2.3L Duratec 4-banger. Gauge (2" face) mounted on steering column. Notice the nylon pressure line is sheathed in clear plastic tubing. The larger piece of clear tubing behind the gauge was so that I could slide it up over the nut.
Next the point of passage through the firewall. I poked a hole in a big rubber grommet right beside the hood release cable and shoved the nylon line through. The clear plastic hose stops about 3/4 inch short but behind the floor covering. You can see the nylon line inside the sheath.
Here is where it comes out the front of the firewall. You can see how the plastic sheath stops short of the firewall as I did not want it jamming the nylon line where it enters the grommet. It comes out between the intake manifold (top) and brake booster (below) and above the steering shaft.
Finally, the connection to the oil pressure port. At the left you can see the line coming down from above the steering shaft and looping down to the port, right beside the oil filter. I have a short (about 1.5") extension off the port so I could get at the connection for the nylon line more easily. The larger line for the last several inches is not full of oil, just discolored. There is some oil where this hose overlaps the other as I liberally squirted 3-in-1 Oil on it so it would slide back in place once the connection was made. The hose clamp is because the sheath gets pretty hot here and the extra oil I used at this end makes it slide off.
Notice the green wire which connects the old dummy gauge sender to ground so the Check Gauges lamp will not be lit. The green wire goes to a bold that used to hold the wire harness, which now is zip tied to a metal loop. If I had put the wire harness back on that bolt it would have pushed hard on the oil pressure line.
