Mallory Ignition 29387 Fuel Pressure Regulator - 3-Port Bypass 3-12 PSI

The Mallory 29387 is a high-performance 3-port bypass fuel pressure regulator designed to maintain consistent fuel pressure throughout all engine operating ranges and load conditions. Essential for carbureted applications using high-pressure fuel pumps, this regulator prevents carburetor flooding while allowing continuous fuel circulation to help reduce vapor lock.

Key Features:

• Adjustable pressure range: 3 to 12 PSI for carbureted applications
• Maximum flow capacity: 200 GPH (gallons per hour)
• Fully machined from 6061-T6 billet aluminum with clear anodized finish
• Specially designed high-flow fuel passages for optimal efficiency
• Quick-acting diaphragm assembly for precise pressure control
• 3-port bypass design with inline return style
• 3/8 inch NPT inlet, three 3/8 inch NPT outlets, and 3/8 inch NPT return
• Boost/vacuum reference port with 1:1 rise ratio
• Compatible with gasoline or alcohol fuels
• Handles unlimited inlet pressure
• Rebuildable design for long-term serviceability

What's Included:

• Fuel pressure regulator
• Mounting bracket for secure installation
• Installation hardware

This universal fuel pressure regulator is ideal for street performance and racing applications where precise fuel delivery is critical. The billet aluminum construction ensures durability and precise tolerances, while the bypass design allows excess fuel to return to the tank, maintaining optimal fuel temperature and pressure control.
