Product Overview
The lift pump supplies low-pressure fuel to the injection system. A weak pump can cause difficult starting, loss of prime, low power under load and fuel starvation that may be mistaken for an injection-pump problem.
The 3936318 reference is used across several Cummins industrial applications. Equipment examples are often listed to include Case 1840 skid steers and 580-series machines, but exact installation should be confirmed by pump number and engine CPL/configuration.
