Radium Engineering Fuel Pulse Damper - R 8AN ORB - Swivel - 20-0776

Standard Operating Range: 40-70psi

Standard operating range should be used on vehicles with a base fuel pressure between 40-70psi. If fuel pressure is static (does not fall or rise with manifold pressure) then no vacuum reference line is needed. If fuel pressure rises or falls lower or higher than the operating range, a vacuum line is needed.
