Frequently Asked Questions

What injector lines fit a Case 550G dozer?

The 550G runs a Cummins 4B engine and uses lines matched to its pump type. We carry both CAV/Lucas pump lines and inline Bosch pump lines, so confirm which pump is on your machine before ordering. Matching the part number to your pump setup is the best way to get the correct line.

Do you sell injector lines as a full set?

Yes. We offer complete injector line sets covering all four lines, including sets for CAV/Lucas pumps and inline Bosch pumps. Individual numbered lines are also available if you only need to replace one.

How do I know if I have a CAV/Lucas or Bosch pump?

Check the injection pump body on your engine, as the CAV/Lucas rotary pump and the inline or 3-bolt Bosch pump have different mounting and line routing. The correct injector lines depend on which pump is fitted. If you are unsure, match the part number or call our parts team at (800) 909-7060.

What does the fuel return line do?

The fuel return line carries excess fuel back from the injectors or pump to the tank. We carry return lines for Cummins 4B and 4BT engines with inline Bosch pumps as well as other 4B and 4BT setups.
