Best Fuel Pressure Upgrades For Blue Spring Engines

The blue spring fuel pressure upgrade is a low-cost modification that increases fuel pressure, helping to prevent damage to injectors and extending their life. It is a fairly simple installation, taking between 25-45 minutes, and is located on the side of the fuel filter housing under the hood. The blue spring kit is an update to the fuel pressure regulator on the secondary fuel filter on top of the engine. The spring itself allows for higher pressure. The blue spring upgrade is recommended for those with aftermarket performance upgrades that challenge the limits of the stock fuel system.

The blue spring kit's impact on fuel pressure and injector life

The blue spring kit is an essential upgrade for Ford Powerstroke owners, as it directly impacts fuel pressure and injector life. The kit includes a blue spring, which is a stiffer and more durable replacement for the factory fuel pressure regulator spring, increasing fuel pressure by around 10%. This is crucial because low fuel pressure can lead to rapid injector wear and even failure.

The blue spring kit is designed to address the issue of low fuel pressure, which can cause the injector plunger to run dry. This is detrimental to the injector as the low tolerances in the machining of its components make them susceptible to even small dimensional changes. Therefore, constant lubrication is necessary to ensure reliable performance and longevity.

By installing the blue spring kit, Ford Powerstroke owners can achieve and maintain optimal fuel pressure levels, which directly impacts injector life. Injectors are precision components that require consistent lubrication to function effectively. Low fuel pressure can lead to incomplete combustion and increased emissions, affecting engine performance and efficiency.

In addition to the spring, the kit also includes gaskets, a plunger, a seat (for 2003-2004 models), new bolts, and a replacement orifice. The installation process is relatively straightforward, with most kits providing easy bolt-on solutions. However, it is recommended that professional mechanics perform the upgrade to avoid potential performance issues or damage to the vehicle.

Overall, the blue spring kit is a cost-effective solution that not only restores fuel pressure but also prolongs injector life and enhances the longevity of the fuel system as a whole. It is a worthwhile investment for any Ford Powerstroke owner experiencing fuel pressure issues or looking to maintain the performance and reliability of their vehicle.

The ease of installation of the blue spring upgrade

The blue spring upgrade is a straightforward process that can be performed by experienced mechanics or skilled enthusiasts. While the exact steps may vary slightly depending on the vehicle's specific year, make, and model, the general installation procedure typically involves the following:

First, it is essential to disconnect both negative battery cables for safety. Next, access to the fuel filter housing is improved by removing the air filter assembly and cold-side intercooler tube. The fuel filter cap and element are then removed, and the fuel filter housing is completely drained.

Afterward, the fuel pressure regulator cover is carefully taken out, usually with a T-27 Torx driver, while maintaining light pressure against the bottom to prevent any parts from being lost due to spring tension. Unless it is also being replaced, the fuel line connected to the regulator cover does not need to be removed.

The lower regulator cover bolts can be challenging to access due to the radiator hose's position. A short T-27 Torx bit designed to fit into a 1/4" nut driver can be helpful here. This allows access without needing to remove or adjust the upper radiator hose.

The spring upgrade kit, provided by various manufacturers, typically includes a new spring, regulator cover gasket, and sometimes additional parts. The old spring, spring seat, and cover gasket are carefully retrieved, taking advantage of the play in the fuel line to pull the cover out of the way and create ample space.

Installation of the new components is then done in reverse order, ensuring that the cover gasket and spring seat O-ring are lightly coated with clean motor oil before installation. Reinstalling the fuel regulator cover requires caution to avoid pinching the gasket, and it is important not to overtighten the bolts to prevent stripping the aluminum threads. Simply tighten them just enough to seat the cover gasket completely.

Next, a new fuel filter element and fuel filter cap O-ring are installed, with the O-ring coated in clean motor oil. The fuel filter cap is then torqued to the specified setting, typically around 10 ft-lbs.

Finally, both negative battery cables are reconnected, and the key is cycled into the "run" position a few times for at least 10 seconds each to fill the fuel filter housing and prime the fuel system. The engine can then be started, and it is important to verify that there are no leaks. Fuel pressure testing may also be performed at this stage to ensure optimal performance.

While the blue spring upgrade is generally an accessible modification, some reviews highlight potential challenges. For example, some users have reported issues with the housing and hardware, such as improperly cut threads or bolts filled with an unknown substance. Therefore, it is essential to carefully inspect and test all components before installation to prevent complications.

The importance of a fuel pressure gauge when installing the blue spring upgrade

The blue spring upgrade is an updated fuel pressure regulator spring released and recommended by Ford Motor Company. The upgrade is designed to improve fuel pressure and extend the life of injectors.

While the blue spring upgrade is a great way to improve fuel pressure, it is important to install a fuel pressure gauge at the same time. This is because the upgrade can sometimes result in fuel pressure that is too high, which can be detrimental to the engine.

A fuel pressure gauge will allow you to monitor your fuel pressure and ensure that it stays within a safe range. Without a gauge, you may not know that you have high fuel pressure until it is too late and your engine has been damaged.

Additionally, a fuel pressure gauge can help you identify other issues with your fuel system, such as a failing fuel pump or leaking fuel lines. By having a fuel pressure gauge installed, you can catch these issues early on and prevent costly repairs down the road.

In conclusion, while the blue spring upgrade is a great way to improve fuel pressure, it is important to also install a fuel pressure gauge to ensure that your fuel pressure stays within a safe range and to catch any potential issues with your fuel system early on.
