That info must have been from early in my thread. On my 84 300D with the OM 617.952 Turbo Diesel Engine my actual maximum oil pressure is 97 psi. The maximum possible Oil pressure is supposed to be 110 psi and that is when the Oil Pump Pressure Relief Valve is fully open.
On that Engine the Oil Cooler Hose is 15mm inside diameter. The 5/8" hose I originally used is not a good fit.
Belmetric sells the correct Oil Cooler Hose and another member said he got it cheaper from a Posch Dealer. It is generally sold in 1 meter lengths which more then you need.
These are numbers that appear on the hose itself.
The Choline-2633 hose is the same Hose used on many of the factory built Oil Cooler hoses. The size in the hose is listed as .1300-15X23-3. The 15 is the inside diameter in mm and the 23 is the outside diameter. I don't know what the -3 means.
On the hose you will see CHOLINE-2633. 1300-15X23-3
The Choline part number is sometimes listed as 2633.1300
