Caterpillar changed the HP pump on the Tier 4 engine. It is not the same Delphi pump that is used on the Tier 3 engine.
I am looking for systems operation testing and adjusting for the TIER 4 C6.6 fuel system.

Thanks in advance

Looks like the 320E LRR Hydraulic Excavator has the C6.6 Tier 4 engine in it.
