Regulator may be rotated a full 360º to facilitate installation

Regulator may be mounted directly to the pump (as shown) or anywhere in-line between the engine & the vacuum pump

These new -12AN vacuum pump mounted regulators are available individually or as an upgrade on our vacuum pump kits.  Manufactured from 6061-T6/651 aluminum and color anodized they mount directly to a MOROSO or AEROSPACE vacuum pump with -12AN fittings.  Unlike the standard vacuum relief valve,  which is a constant leak at all vacuum levels, this regulator only draws in ambient air when the set point is reached.  This could help reduce some of the smoking associated with the standard vacuum relief valve at idle and lower engine speeds.

·        When regulator set point is reached, ambient air is drawn directly into the vacuum pump helping it run cooler.

·        By placing the regulator “outside” the crankcase area, the excess air the regulator is bypassing will no longer be passing thru the engine to the pump.  It now flows directly into the pump, reducing the possibility of oil being scavenged from the engine.

·        Mounts directly to the vacuum pump.  No need to drill and tap head or valve covers, or weld in a bung to accept the regulator.

·        Regulator maybe rotated 360º for ideal positioning.

·        Infinitely adjustable.  No springs or shims to “fool” with.

·        Screened inlet keeps dirt out of your pump and out of your engine.
