Oil Gauge Line Question......

[A383Wing]

Curious as to what you would use for an aftermarket mechanical oil pressure line from engine to gauge...plastic or copper line?

Plastic is what comes in the gauge kits, but copper was used at the factory back in the 60's & 70's

My 64 Nova SS had the rally gauges, and the line from the block to the dash gauge was copper 1/8" line

Most 70's GMC & Chev C10 and higher trucks that had the factory gauges in the dash also used a copper line from engine block to the dash gauge....

Just wonder about others opinion as to preference here

If i had to do it again, i would use braided and be done with it.

I have no opinion on the subject, but I will say my car came with a plastic line to the after market oil pressure gauge, its been functional in the 10 years I've owned it, and  it was old when I got it. It's not something I'd worry about immensely.

I've been using my after market oil gauge with the plastic line for the last 15 years with no problem. The problem with the plastic line is that it can dry out and start cracking and then you would have an oil leak in the car. If you are racing the car down the strip, the techs might say something about it. I've been thinking of switching mine to Braided line.

Get rid of that plastic tubing. After that plastic line cracks or rubs on an edge or something moves and the plastic line burns on something hot and the oil is squirting all over the motor or worse like under the dash, your just kick yourself in the a$$ for not using copper or what ever the braider stuff is that coonhunter said.

Agreed x2.  Braided stainless.  One and done.

Or go electric and not have any line.

My 1955 Plymouth had a hard steel line from the block to a rubber section about 6" long, then more hard steel line to the gauge. Kind of a pain to deal with the hard steel line under the dash. I replaced it with braided stainless. I would have just replaced the gauge with a 2" electrical, but didn't want to modify the bezel. Plus, where the fitting is on the side of the flathead six below and behind the starter, I'm not sure there's room for an electrical sender.

I'm liking the steel braided oil line, the smallest I can find is 1/4".....is that the smallest they make reasonably priced?

Where does one get the fittings to go on the ends to connect to the engine and gauge? The threads on the gauge are 1/8th pipe thread

I bought two pre-made AN-3 lines of the lengths I needed off Ebay and used a bulkhead connector to pass through the firewall.
