Also known as fuel distributor pipe, is used in pulsed fuel injection system for petrol and diesel engines. Its main function is to deliver fuel to injectors. To stabilise fuel pressure at the injectors.

• Increased fuel efficiency.
  
• Uniform fuel pressure.
  
• Reduces emission - environment friendly - meets fuel emission norms.
  
• Avoids fuel pressure fluctuation while injecting fuel in cylinder.
  
• Fuel economy.
  
• Higher constant pressure throughout the injection pressure.
  
• Low operating power requirement.
  
• Combustion noise substantially reduced.
  
• Use of higher injection pressures improves low injection speed torque.
