The pump would be damaged by sitting stationary. The after fire is caused by the conbination of residual fuel, compliments of your CIS, hot exhaust components and the fresh air provided by your air pump. These ingredients were processed inaudibly by the CAT prior to removal. The noise will never go completely away but if it's currenty obnoxious, the removal of fresh air will help.
