Given thought to buy the ‘Best Injectors for LB7 Duramax’

You must consider a few things when buying the best LB7 injectors, such as Fuel injector type, the flow rate, and the size. You have bought your vehicle costing a lot, right? So, why not take care of the vehicle and ensure a long lifespan? You are probably one of those enthusiasts who have been running your car with the help of diesel. Why don’t you have constant maintenance then? As with all vehicle components, choosing a fuel injector for ongoing maintenance would not be a bad idea at all. You’ll see lots of fuel injectors available in the global market. Within a large quantity of products, be mindful of choosing the right fuel injectors for LB7 Duramax. We have explained the real factors that you need to consider before purchasing LB7 injectors.

  • The type of fuel injector

Without realizing the type of fuel injector, you can’t go for purchasing the right solution. We have read four types of fuel injectors available in the market.

  • Diesel fuel injector
  • Performance fuel injector
  • Petrol fuel injector, and
  • Stock injector

Last Friday, I received a question that was asking me, ‘Does an LB7 have a fuel pump?’ Indeed, every LB7 Duramax from 2001 to the LML in 2016 has a fuel pump. Once you have identified the type of fuel injector, don’t delay to purchase from high-grade manufacturers.

  • The flow rate

Then, the flow rate is essential to choose a fuel injector. The flow rate is usually measured in PSI. If you selected a specific manufacturer, please read the manufacturer’s description on the injector how much flow rate you’re provided with! Let me give an example. Most of the car has 3 bar diesel fuel injector. For them, the flow rate is appropriate with 43.1 PSI.

  • Right-sized injectors

The size of the best replacement injectors for LB7 should be accurate. People make a mistake choosing the right sized fuel injectors. Indeed, maximum aftermarket or replacement injectors have the same size but different construction. I feel you’re a mechanic yourself, and you can feel the correct size of an LB7 fuel injector. If not purchased in the right size, it will damage the car and cause an unexpected accident.

Lb7 Injectors’ Replacement: Lb7 Injectors Remove Process

Well, the removal process of LB7 Duramax Fuel Injectors is explained step by step below. Take a look. Indeed, the automobile engine can be intimidating during internal operation. Jokes apart! With a proper tool and techniques, it is possible to complete the task at hand. You may seek the solution, ‘How to Remove LB7 Duramax?’

We have done our operation for Duramax Diesel LB7 Engine 2001-2004. GMC or Chevrolet Pick-up Truck is most often vehicles that contain that engine.

  • Firstly, mandatory work is to ‘Drain the Coolant.’ Then, find the drain valve on the passenger side. The valve is mostly engineered besides the wheel. You can use a bucket and a cloth to capture the debris. These materials will work as filtration.
  • Then, disconnect the battery once you see the coolant is draining! Disconnecting the battery will prevent unexpected damage to the ECM and modules.
  • Once you have disconnected the battery successfully, remove the A/C condenser. Using a fan belt tool is recommended. Keep it with a 1/2 drive ratchet. You’ve to remove the tensioner pulley nut off the engine (Passenger Side). After removing the A/C condenser, fold the condenser by the passenger side battery.
  • Do you see a water thermostat and coolant neck at this point? Remove it. Also, remove the FICM. FICM means the ‘Fuel injection Control Module.’ Remove it from the engine. Through this, you can go under the valve corners. All you need to do is sliding the plastic tabs outwards and remove the FICM accurately.
  • You should then gradually remove the Glow Plug Harness, Fuel Line, Fuel Injector Keys, Harness of the Fuel Injectors, Returned Lines, and Fuel Injector.

At length, work with the injector cups to replace all the injectors. You should watch this tutorial to remove LB7 Duramax injectors more correctly.   

Lb7 Injectors’ Replacement: Lb7 Injectors Install Process

  • Start removing the passenger side wheel, and then remove the inside fender made in ‘Black Plastic.’
  • Draining the radiator’s coolant is mandatory, and you should do it only by removing the drain plug on the bottom passenger’s side. If the coolant is not drained, there is a high possibility of making the cylinder damaged if an injector cup comes out when removing the existing injector.
  • Now, unhook the blue turbo intake hose by loosening the 10mm nut on the clamp. Pull the hose off! Do the unhooking process by the top of the engine and set it aside. Remove all the tubing, intake, and fuel filter bracket from the passenger side and cut off the Fuel Injector Control Module (FICM).
  • You will see slide tabs on the FICM. Disconnect the accounts by the driver’s side on the tab. After disconnecting all the engine wires successfully, remove the FF ad FICM precisely.
