Could you explane the difference between regular pump and gold pump and the reason why it's needed? I use a 3stage pump on the zetec but seems like the K-sport has a totaly different system. Does it use the original hp pump for pressure side?
It retains the standard hp pump for oil pressure. The original scavange pumps are vane type and cannot cope over 7200rpm and they great air the the system. The gold pump is gear type and ok to 9000 rpm. This was why i created such a mess at donnington!
