Where to run oil pressure line

[maldotcom2]

I'm installing a mechanical oil pressure gauge in the area below the CD player. What is the best route from the oil pressure sender? It's manual so the clutch hole is already taken up.

not legal. why not just electrical gauges?

I've already got all the parts for mechanical set up. Just want to know the most direct route, or where is a good place to drill through the firewall?

Sorry mate but I'm with Stocky on this one, they are not legal. I had one in my HT years ago and it developed a slight drip at the back where the oil hose went in.

If you're adamant about using it though you'll just have to spend a while nutting out where the best route would be, remember you can't have it anywhere that it might be inclined to kink. And if it blows some time down the track, you could potentially have HOT OIL SPRAYING ALL OVER THE INSIDE OF YOUR CAR AND IT'S OCCUPANTS.

Alright, when i was shopping for one i was told mechanical all the way. If i sell it and buy an electrical one where should i run the wires?

I'm not sure that they are illegal - what happens when a heater hose bursts and sprays hot coolant over the inside of the car and it's occupants?...same deal. The inside diameter of the gauge tubing is tiny - about 1mm so that wouldn't squirt much out at all. A heater hose is 12mm the same as a garden hose.
Correctly installed there should be no risk. Cars made up to the 60's always had mechanical gauges fitted.
Use your common sense when installing and follow the instructions and you can't go wrong.
That's just my opinion for what it's worth.

you dont see many heater hoses mounted on an a pillar, or top of the dash. they are definately illegal on modern cars.

I wouldn't be going back to that salesman then... Mechanical gauges are no more accurate (assuming you get a decent electrical gauge), and wire is a lot easier to run than hoses...

Why would you want to drill a new hole in the firewall? There are plenty of them already... Just pick away at one of the existing grommets, and fill it in when you're done.

Mechanical gauge is even harder to run and setup, you need to run wiring for the back light anyway. It will be so much easier to use an electric one to start with. The best way to run it is probably goin to be into the gaurd and then back into the cab. On the passenger side there is a gromment the aerial uses, i guess there may be one on the driver side too.

I'm just guessing, but I think you'll find mounting any gauge - electric or mechanical - on top of the dash or on a pillar is illegal - it can be deemed to obscure the driver's vision just like a stone chip on your windscreen.

Read the original post and you will see that maldotcom2 is mounting the gauge "in the area below the CD player".
