Quick Secondary Air Pump Question I have a '98 318ti M44 There is a Secondary Air Pump mounted on the front of the engine. From this air pump is a plastic hose. [Part number: 11-72-1-433-821 ] Now, is this hose supposed to be securely fastened to the air pump? I notice that there is air leaking at end of the plastic hose because it is not securely fastened. Am I supposed to have any secondary air leak there or should it be nice and snug? Thanks! |
