Front of car and nose metal is clean, except behind the hoses were some build up appears. Lines and fittings are Summit Racing brand
Anyone know who makes the hoses & fittings for Summit?

Perhaps it's just the photo, but the 3rd photo looks like the film is on the lower section of the hose, but not on the upper section (the braid is more clearly visible). Perhaps the upper section is above the opening and not picking up contaminants through there - providing a clue as to where it's coming from.
Do you have a puller fan as well that's drawing in those contaminants while in traffic?
