Cosworth YB 2WD | Sierra | Billet 3.5 Bar Fuel Pressure Regulator

2WD Cosworth Fuel Pressure Regulator supplied with replaceable Bosch insert.

Direct replacement part that is designed to match the original Weber fuel pressure regulator as closely as possible. Custom CNC machined housing as well as custom CNC Machined connectors to ensure correct fit – we found “off the shelf” items used in others were too variable in size.. Fittings are also sealed with correct fuel grade sealant and not PTFE tape.

Can also be used for the RS500, but please contact us to supply an additional fitting to use in place of the plug fitted.
