Product Overview
Its job is to move fuel from the tank/filter side toward the injection system at low pressure. Hard starting, loss of power, inability to prime and fuel starvation can occur when a feed pump fails, but plugged filters or cracked suction hoses are equally common causes.
The source application set includes Yanmar JV25CR-5 and JW30-series machines plus Komatsu WA20-1, WA30-3 and WA40-2 loaders. Since these models can have engine or serial-number revisions, compare the old pump body, lever/drive arrangement, port orientation and any stamped number before ordering.
