got a Commercial G101-2-20 on my truck now. is this Permco pump a straight replacement or am i gonna be re-hydraulic connections everything

Question by: Brett S on Sep 18, 2025, 3:44 PM

This DM400 series unit is called out as a replacement for the Commercial G101-2-20. It is a remote mount, 3-line dump pump with a 1-1/4 NPT inlet and 3/4 NPT pressure and 3/4 NPT return ports, so the hydraulic connections is set up for that 3-line style circuit.
