Is there a plastic replacement for the steel oil pressure line to the gauge? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Looking for a plastic hose to replace the steel line going to the pressure gauge.
Has anyone ever done this?

The consensus on most car/truck forums shows a preference for a copper line vs plastic.

But, yes I've seen plastic ones from various part vendors.

I saw them on eBay and I think on Summit.

Steel bends better and doesn't break from fatigue like copper, which work hardens and cracks. Nylon is fine, but everywhere it makes contact, it should have something on it in case of chafing.

I bought a kit from a member who was putting together a kit with fittings and all a few years back

Locdoc makes em, search oil line and locdoc

Theres a handful on Summit Racing. I'm sure Jegs, Autometer, and and similar have them also. Some braided stainless too.

I think I have seen the plastic ones at Pep Boys.

I had a plastic line once, until it blew off and dumped hot oil in the car, never again.

**VictoriaHardware** · 11-25-2020, 11:45 AM

I had a plastic line touch a header while on the running dyno. Pumped flaming oil all over the dyno room till the fire extinguisher calmed things down.

But I have had both the plastic and the copper leak inside the cab. I use the electric type now. Not as accurate but accurate enough for driving around town.

**LostMy65** · 11-25-2020, 12:33 PM

My plastic one got brittle over the years and then cracked and blew oil all over my engine. Better than in the cab I guess.

**Corts60** · 11-26-2020, 04:32 PM

Please don't use plastic. All the reasons above are true. They are not trustworthy. Go with copper.

**Steeveedee** · 11-26-2020, 09:41 PM

I'd stay with steel, or use NiCopp. Regular copper work hardens and will eventually crack.

Asshat · 11-28-2020, 03:36 PM

Ok. I think I’ll stick with steel.
Thanks!

On my 1972 I purchased an AN-4 braided SS line and used brass fittings to attach. Flexible and less prone to crack than plastic, steel, or copper.

Just another option.

There are some pictures in this thread.

Yes stay away from the plastic lines.
They do work for short term use but after some years they will become brittle and crack and break in a million places and pieces.

straight6chevyguy · 12-03-2020, 04:36 PM

I have used copper lines and they seem to work fine for me.

**The Rocknrod** · 12-03-2020, 04:42 PM

I had my oil pressure gauge updated to the next series gauge and matching sender. No tubes for me.
