Fuel Pressure: Blue Spring Upgrade Benefits

The blue spring mod or blue spring upgrade is an updated fuel pressure regulator spring released and recommended by Ford Motor Company. The blue spring is slightly stiffer than the factory-installed spring and may be made of a more suitable material that resists deformation over time. It is said to increase fuel pressure by approximately 10%. The blue spring upgrade is a low-cost modification that can help prevent damage to injectors and even extend their life.

The blue spring upgrade increases fuel pressure by 10%

The blue spring upgrade is an updated fuel pressure regulator spring released and recommended by Ford Motor Company. The blue spring mod increases fuel pressure by around 10%. The name comes from the blue colour of the upgraded spring, which allows technicians to easily recognise that the upgraded part has been installed. The blue spring is slightly longer and stiffer than the factory-installed spring and may be made from a more suitable material that resists deformation over time.

The blue spring upgrade is important because rapid injector wear and even failure can result from low fuel pressure and/or fuel starvation. This is because low fuel pressure can cause the plunger in the injector to run dry, and the low tolerances in the machining of the injector components make them susceptible to even small dimensional changes. Therefore, constant lubrication is necessary for a long, reliable service life. A minimum fuel pressure of 45 psi is necessary at all times, including wide-open-throttle and full-load conditions, to maximise engine performance and ensure proper injector operation.

Users have reported that the blue spring upgrade has made a big change in how their trucks run, with significantly more responsive throttles. However, one user has reported that after installing the blue spring kit, their cruising EGTs increased by 75-100 degrees. Another user has reported that their new spring was not keeping up with their injectors, with fuel pressure dropping below 50 psi at about 60% throttle.

There are alternative options to the blue spring upgrade, such as the EightySixd Fuel Pressure Spring, which is said to outperform the blue spring upgrade. The EightySixd spring raises fuel pressure to about 70-80 psi at idle and 50-55 psi at WOT, compared to the blue spring's 60-65 psi at idle and 45-50 psi at WOT.

The blue spring upgrade improves throttle response

The blue spring upgrade is a simple modification that can significantly improve the throttle response of your Ford 6.0L Power Stroke engine. This upgrade involves replacing the stock fuel pressure regulator spring with an updated blue spring, which is slightly stiffer and made of a more durable material.

The benefits of the blue spring upgrade are twofold. Firstly, it increases fuel pressure by approximately 10%, ensuring that your engine consistently receives the fuel pressure it needs to perform at its best. This is especially noticeable when you floor the throttle, as the engine now has access to a more ample fuel supply, resulting in a more immediate and powerful response. Secondly, the blue spring upgrade helps protect your injectors. Low fuel pressure can lead to rapid injector wear and even failure, as it causes the injector plunger to run dry. By maintaining adequate fuel pressure, the blue spring upgrade extends the lifespan of your injectors, saving you money on costly repairs or replacements.

In addition to improved throttle response and injector protection, some users have also reported increased fuel efficiency after performing the blue spring upgrade. While not a guaranteed outcome, it is certainly an added benefit that some drivers have experienced.

The blue spring upgrade is relatively straightforward to install and can be completed in a few hours by anyone with basic mechanical skills. The process involves removing the fuel filter cap and element, draining the fuel filter housing, and then carefully removing the old spring and installing the new one. It is important to follow the correct procedure and take the necessary precautions when working with fuel system components.

Overall, the blue spring upgrade is a highly recommended modification for any Ford 6.0L Power Stroke owner seeking improved throttle response, enhanced injector protection, and potentially better fuel efficiency. It is a cost-effective upgrade that can make a noticeable difference in the performance and reliability of your vehicle.
