Hi everyone, drowning in various NOS engine back breather, heater, and coolant hoses here that seem to have the colour from the cotton weave faded to a dull black or grey colour. I have now seen them in both finishes, and was wondering what is more "correct" as per Datsun. Is it January, 1970 "period correct" to dye these hoses so that they become black again, whilst repainting any markings or insignias back onto the hoses? I've done the hose dying countless times and it always comes out amazing. so all I'm wondering is if it's "OE" to bring it back to black, or did they come "grey-ish" from factory. Thanks. Raff
