Oil pressure line??

Does anyone make a copper or steel line for the mechanical oil pressure gauge..

Had a real close call today and need to find a way to shield the plastic line or change it out entirely... It is less than half inch from the header...


Thanks in advance..

Re: Oil pressure line??

Do NOT use Copper or Nylon in the Engine Compartment. I can't say Steel is any better. I recommend Hi-Pressure Hydraulic Rubber Hose to a 3 Outlet Bronze Adapter mounted in the Firewall then run Nylon to the Mechanical Cab Gauge (continue with the Hydraulic Hose under the Dash if Room Permits it). Use the 2nd Bronze Engine Compartment outlet to mount the Idiot Light Oil Pressure Sensor.

Copper, Nylon and Steel Oil Lines Break in the Engine Compartment as the engine Torques against the Firewall & Flex the Oil Line. Been there done that and learned my lesson years ago.

Re: Oil pressure line??

Will the 1/8 Cooper line use the same fittings as the nylon line I have now..

I don't think steel braided will last this closet the header

Re: Oil pressure line??

Do you have any tractor or hydraulic repair companies near you ? If so, take the fittings to them and they can make a custom line for you to your exact specs. It would be a high pressure rubber line with a braided cover. I do this all the time with oil, coolant, and hydraulic lines for my motor coach. I've paid as low as 25.00 and as high as 150.00 depending on length and whether I wanted straight, 90, 135, 180, or swivel fittings.

Re: Oil pressure line??

Is your line coming straight out of the block above the oil filter? If so use a 90 degree fitting out of the block and run the braided autometer line

I just went to an auto part store and had a copper line made up for me with all of the fittings.

Napa has them in a kit but it's a fixed length.

Re: Oil pressure line??

Did copper and plastic for 30 years but when thought of the copper taking the vibration and plastic possiabily melting in high heat, I went to a small steel braided line from the motor thru the firewall into the gauge. It may be an over kill but at least I know its safe.

Re: Oil pressure line??

Went to the speed shop picked up the copper line... Attached to block coiled the line three times to help with vibration.. then through grommet in firewall ..

Noticed when I first started it with the new copper line that the gauge read 20lbs for about 20 seconds before shooting up to the usual 65..is this normal until the air clears the line or is the gauge on it's way out??

Copper tubing is a BAD idea for an oil pressure line; it will work-harden with vibration and eventually fracture - GM never used it. GM used copper-plated steel lines.

Paragon sells a complete kit for big-blocks with a coiled copper-plated steel line and the fittings for both ends, listed for '67 Corvette usage.

Re: Oil pressure line??

Say no to copper and nylon. You want a good steel braided line. This is what ya want and it will come with different fittings. I swapped mine from a nylon line which the car came with and the fittings this came with matched up.
