I found what looks to be a small crack in the suction of my 12JG. It is hard to tell if it is just in the coating. This is on the port side only. Starboard side looks fine. No evidence of the crack on the inside. Is this a typical place for a crack to develop? Is it safe to use or should I start looking for a new suction housing. This is in my 21' Daytona with a full set back and basically stock 454.
