The Peterson Fluid Systems primer filter mount with -10AN fittings (right-to-left flow) is built for System 1 post configurations and includes a compact R4 rotor primer pump. Using a standard drill, the pump can achieve roughly 20 psi fast to pre-oil bearing surfaces prior to starting. The mount is machined from billet aluminum and uses AN ports for hose connections; it can be mounted to tube, firewall, or tank; bracket sold separately.
