Could it be that it is s a red rubber hose that was painted and now the paint is coming off? On the left-hand side it appears there might be white lettering on the hose.

Does it rub or scrape off ?

Not sure - It's on a coach that I'm looking to buy, but it's out of state, so I'm trying to determine if it's worth the trip.

Since you have the original photo could you blow it up enough to tell if that is writing on the left-hand hose?

Mu guess would be that it is leak detector dye used for AC. Maybe a hose blew at one point, or PO added refrigerant can with dye and made a mess disconnecting the charge hose.

my guess is a bit simplistic but seems as if the paint helps follow various hoses or sections of the engine?

or maybe old hippies gone rogue with the flower power thing...

actually I know I've seen this before on some sort of industrial vehicle or old tractor. I've a very vague recollection I know I never actually asked about it
