Its cheap insurance really when you consider the cost of a new motor. My pump was at its limit with 274rwkw Link to comment Share on other sites More sharing options...

My pump was at its limit with 274rwkwexcuse my ignorance, but how is it insuring against a new motor?if the fuel pump cant handle the power does that wreck your motor fairly quickly?also is there a difference between the BA and BF pumps?
