Product Overview
The lift pump sits on the supply side of the diesel fuel system and draws fuel toward the injection system. Hard starting, loss of power under load, repeated loss of prime, or fuel leakage around the pump can point to a weak or damaged lift pump after filters, lines, and tank supply have been checked.
Cross-reference research for this pump also ties the same basic pump format to several Kubota L/M-series machines and Bobcat equipment using compatible Kubota diesel engines. Because those applications span multiple equipment families, matching the mounting pattern and original part number is the safest way to confirm the pump.

Frequently Asked Questions
Q: Can a bad lift pump cause a diesel to start and then lose power?
A: Yes. A weak supply pump can allow the injection system to starve under load, although clogged filters, air leaks, and tank restrictions can cause similar symptoms.
Q: Does Bobcat 6655216 cross to this pump family?
A: Yes, it appears in cross-reference listings for the same pump format; verify the physical configuration on your machine before installation.
