    Twin piston is to assist air flow meter cars, otherwise when on vacum (idle) the valve will be open which will be fooling the air flow meter and giving lump idle. With a 2nd piston it basically has a 2nd spring and little plastic piston within so when the main piston is being sucked by vacum the other piston is being pushed with the 2nd spring over the hole.

    Not really a dump valve question but, what size Inner Diameter vacuum hose do you guys use for your dump valve and vacuum system. 3mm? 4mm?

    Mate you've had an extra 30 years to brush up on yours. When I get to be as old as mumrah from thundercats we can compare writing styles.

    Or Bumrah from Thunderpants (which was a parody in Doc Croc's Round The Bend).
