This is a solid, high-output P-Pump setup built for steering systems that need consistent pressure and smooth control without getting hot and bothered halfway through a pull or a trail.
At the heart of it is a PSC 19 mL P Series pump matched with a remote-fill reservoir, so you’ve got proper fluid capacity and easier service access when things get tight under the hood. These come set up with your choice of pressure and feed sizes, so you can match the rest of your system instead of trying to make mismatched parts play nice.
The included flow control fitting keeps the steering predictable, not twitchy, and the remote reservoir helps keep aeration down where it belongs. Everything here is built to work together right out of the box—no chasing down little pieces or making extra trips to finish the job.
You end up with a pump that’s steady at idle, strong under load, and reliable when the terrain stops being forgiving.
