MAC AFRIC Fuel Injection Pump Pressure Tester Gauge Kit

Fuel Pressure Diagnostic Kit for Gasoline Engines

General Overview:

• Purpose: This diagnostic kit is designed to evaluate fuel pressure in gasoline/gas engine fuel injection pump systems, essential for diagnosing fuel system issues. It is not suitable for diesel high-pressure injection pumps or direct-injection engines due to the gauge's limited pressure range.
• Key Usage: The kit helps detect fuel pressure irregularities that can impact engine performance, such as inadequate pressure from fuel supply issues, faulty fuel pumps, or a malfunctioning fuel pressure regulator.

Compatibility:

• Engine Types: Works for most gasoline/gas engine fuel injection pump systems. Excludes systems like:
  • Bosch, CIS Jetronic, and Throttle Body Systems on GM vehicles.
  • Diesel high-pressure injection pumps.
  • High-pressure fuel tracks on direct-injection engines.
• Connection Types:
  • 35.5 cm Hose: For connecting to the 1/4" SAE Schrader valve on the fuel pump.
  • 28 cm Hose: Compatible with small Schrader valves, commonly found in certain Ford models.
  • 20 cm Hose: Suitable for the M6 fuel pressure test port.
  • 1/4" Barbed Brass Fitting: Direct connection to special test outlets on engines.
  • Aluminum Tee Fitting: Facilitates seamless connection between the fuel pump and engine.

Kit Components:

• Pressure Gauge: 7.6 cm dial with a dual-color-coded scale, offering readings from 0-100psi (0-7bar).
• Hoses:
  • 35.5 cm Hose (Long)
  • 28 cm Hose (Medium)
  • 20 cm Hose (Short)
  • 6.35 mm Inner Diameter x 6.35 cm Length Hose
  • 9.52 mm Inner Diameter x 7.62 cm Length Hose
• Fittings:
  • 1x Brass Fitting: 6.35 mm Barbed x 1/4"-18NPT.
  • 1x Tee Fitting: Aluminum tee parts: 6.35 mm & 9.52 mm barbed x 1/8"-24NPT, Brass parts: 1/8"-27NPT x 1/4"-18NPT.
• 2x Hose Clamps: Secure the hoses in place for stable and accurate pressure readings.

Essential Features:

• Rubber Protective Cover: For enhanced durability and protection during use.
• Material Construction: Hoses are made from a combination of rubber and nylon resin, reinforcing stress resistance.
• Pressure Gauge: Includes a dual-color-coded scale for quick and accurate readings, ensuring easy interpretation of pressure levels.
• No Pressure Relief Valve: The kit lacks a pressure relief valve, so its important to relieve pressure by covering the hose connection with cloth before detaching.

How to Use:

1. Attach the Gauge: Connect the appropriate hose to the fuel pump or fuel pressure test port.
2. Read Pressure: Observe the gauge dial for pressure readings. Compare these with the manufacturers recommended fuel pressure range.
3. Diagnose Issues:
   • Inadequate Fuel Pressure: May indicate issues like a faulty fuel pump, regulator malfunction, or supply complications.
   • Excessive Fuel Pressure: Could be caused by a damaged fuel pressure regulator or clogged outlet return line, leading to issues like increased emissions, poor combustion, and higher fuel consumption.

Applications:

• Fuel Pressure Evaluation: Ideal for diagnosing fuel pressure issues in gasoline engines.
• Fuel System Diagnosis: Helps determine if the fuel system is supplying sufficient fuel to the engine for optimal performance.
• Engine Performance Monitoring: Ensures the engine operates efficiently and avoids common issues like engine stalling, delayed starts, or poor acceleration due to improper fuel pressure.
