hey guys ive just removed my bosch 044 pump as im returning the car to stock and i installed the stock vl pump ( second hand) but was told it was a working item now when i go to start the car i can hear it prime but no fuel is coming out.also when i installed the 044 pump i removed the fuel dampener but haven't put it back yet with the stock pump could this be causing my problem of no fuel or im a need of a new pump cheers
