Help with oil line identification

[javadog]

I was rummaging through some parts that I won't be needing and I came across this oil line. Can anybody identify it, from the photos? The fittings are aluminum, 30mm in size and they are marked:

OLN NW20 1/72
PRDR . 18 BAR
H

Thanks,

I think that it's the line from the oil cooler to the tank (pump suction) for 65-71. Are you selling?

Are you selling?

It depends on what it is. If it's for a '72, I'll need it. If it's for an earlier car, I'd probably sell it. It might even be from a 916-6. It's been so long since I crawled under any of these cars, my memory is a little rusty.

Thanks,

It might be the line from the thermostat to the oil tank for a 72. It looks to be about the right length. It has the larger fittings for the later car, right?

Right, I'm thinking the fittings are 30mm, if my memory is any good.

Thanks,
Jeff
