HiSport Fuel Injection Pressure Regulator Kit 3.8BAR with Clip & Snap Ring — OE Fit, Pre-tested

HiSport's 3.8BAR fuel injection pressure regulator kit is a direct-replacement component that controls fuel rail pressure to maintain consistent engine performance.

This HiSport kit includes the 3.8BAR regulator, a retaining clip and a snap ring engineered to match original equipment fit and function. Manufactured and tested to meet or exceed OE standards, the regulator is intended as a one-to-one swap for compatible vehicles that use OEM part numbers 19236428 and 2173299. Before ordering, verify fitment against your vehicle’s part number and inspect the images and description closely to ensure compatibility.

How does this regulator affect vehicle performance?

The regulator keeps fuel pressure stable in the rail, helping the engine receive the correct amount of fuel under varying loads and temperatures. Proper fuel pressure supports smoother idling, predictable throttle response and efficient combustion without overloading injectors.

• Maintains a steady 3.8BAR reference pressure across operating conditions
• Prevents pressure spikes that can cause lean or rich running
• Supports consistent injector flow and engine responsiveness

What comes in the HiSport kit and why are the clip and snap ring included?

This kit supplies the regulator plus the necessary hardware—clip and snap ring—so you can replace the entire assembly without hunting additional parts. The retaining components ensure the regulator seats securely in the fuel rail and preserves proper sealing and alignment.

• 3.8BAR pressure regulator pre-tested for quality assurance
• Durable metal snap ring for reliable retention
• Curved clip to lock the regulator into the fuel rail connector

How do I confirm this part fits my vehicle?

Check your vehicle’s existing part number against the listed OEM references (19236428, 2173299). If the numbers match or your vehicle’s service manual cites the same specification, the regulator should be compatible. When in doubt, compare physical dimensions and connection type or contact a technician.

• Confirm OEM part numbers before ordering
• Compare connector style, mounting face, and pressure rating
• Contact HiSport or a professional mechanic for verification help

Is installation difficult and what should I prepare?

Replacement is straightforward for experienced DIYers but requires attention to fuel-system safety. Relieve rail pressure and disconnect the battery before removal, and inspect O-rings and seals during installation. Professional installation is recommended if you lack fuel-system experience.

• Relieve fuel pressure before disconnecting lines
• Use proper tools for snap ring removal and clip installation
• Replace seals if worn and verify no leaks after installation

Who is this for: The HiSport 3.8BAR fuel injection pressure regulator kit is suited to vehicle owners and technicians needing a reliable OE-style replacement for systems that specify part numbers 19236428 or 2173299. It’s ideal for those restoring proper fuel pressure control—whether repairing a failing regulator, addressing inconsistent fuel delivery, or performing routine fuel-system maintenance. If you require exact fitment details or installation guidance, consult your vehicle’s service manual or a qualified mechanic.
