Hey all Bought a bunch of different diameters of 30R9 fuel hose, I bought some to change out the blow-by lines as well. The blow-by uses the same diameter of lines as some of the coolant lines. Wondering if 30R9 can be used for coolant as well? Regards
Coolant hose used for fuel will quickly become soft and mushy and leak. Fuel hose used on coolant will slowly become hard and brittle. They are not compatible compounds either way.
A subcontractor guy who supplies and custom makes all the pressure hoses for the different departments and shops where I work at, got it for me
