The Fuel System Spring Compressor is a service tool for controlled compression of lifter springs inside fuel pump assemblies during servicing operations. It is used when fuel pump plunger and barrel assemblies are removed and installed, allowing the spring load to be managed safely and smoothly. The tool clamps directly onto the side of the pump housing, creating a stable working position without relying on adjacent pump structures.Attributes:• Maintains controlled working conditions inside confined pump spaces.• Improves workflow efficiency during repeated pump service tasks.• Provides stable positioning by clamping directly to the pump housing.Applications: The Fuel System Spring Compressor is used on fuel pump assemblies where lifter springs must be compressed during the removal and installation of plunger and barrel components.
