The Sinister Diesel Remanufactured High Pressure Oil Pump (HPOP) is an aftermarket replacement for the 2004.5-2007 Ford 6.0L Powerstroke. It meets and exceeds OEM standards, ensuring reliable high-pressure oil delivery for improved performance. The pump undergoes a thorough remanufacturing process, with worn components replaced by OEM-spec parts, making it a dependable and cost-effective alternative to a new OEM pump.

The Sinister Diesel Regulated Fuel Return Kit is designed for 2003-2007 Ford F-250 and F-350 Super Duty trucks with a 6.0L Powerstroke engine. It features CNC machined billet aluminum parts, stainless steel braided fuel lines, and nickel-plated fittings. The kit includes an adjustable fuel regulator and pressure gauge to maintain consistent fuel pressure, improving injector longevity and performance. It comes as a complete package with no additional parts required.

The updated “Blue Spring” kit restores factory fuel pressure, typically increasing it by 10 psi in 6.0L engines. This helps prevent injectors from outflowing the stock fuel pump, reducing air in the system and extending injector life. Benefits include quieter idle, faster throttle response, and quicker turbo spool-up. The kit includes all necessary O-rings and hard parts, along with a stronger billet aluminum housing to prevent leaks.

The updated “Blue Spring” kit easily installs in 30 minutes and increases fuel pressure, typically by 10 psi, restoring it to factory levels. This added pressure helps prevent injector issues, improves engine responsiveness, and enhances turbo spool-up. The kit includes O-rings and hard parts for rebuilding the fuel pressure housing, along with an adjustable screw for fine-tuning pressure, especially for larger injectors. It also features a durable billet aluminum housing to prevent leaks, replacing the weaker factory cast aluminum component.

A cracked fuel filter cap can cause air leaks, hard starting, fuel injector problems, and fuel leaks on hot engines. The Sinister Diesel Fuel Filter Cap solves these issues with a durable, corrosion-resistant design made from solid aluminum and includes a 1/8″ NPT port for fuel pressure testing.

Sinister Diesel 6.0 PowerStroke injectors are OEM replacements for 2003-2004 Ford F-Series Super Duty trucks, offering a cost-effective alternative to dealer prices. Built on remanufactured bodies with all-new components, they ensure optimal performance, reliability, and improved cold-weather operation. Features include new electrical connectors, injector coils, harness assemblies, and a redesigned spool valve to prevent stiction. Sold as a full set of 8, they come with a 24-month, unlimited-mileage warranty.

The updated “Blue Spring” kit is an easy 30-minute install that increases fuel pressure by approximately 10 psi, restoring it to factory levels. Higher fuel pressure helps prevent injector issues, improving longevity and performance. Most trucks will idle quieter, rev faster, and experience quicker turbo spool-up.

The updated “Blue Spring” kit is an easy 30-minute install that restores fuel pressure in 6.0L Powerstroke engines, typically increasing it by 10 psi. Higher fuel pressure prevents air in the injectors, improving longevity and performance. Benefits include quieter idling, faster revs, and quicker turbo spool-up. The kit includes all necessary O-rings and parts, along with a billet aluminum housing that is stronger and more leak-resistant than the factory version. An adjustable screw allows for fine-tuning fuel pressure, making it ideal for larger injectors or long-term maintenance. Recommended pressure is 55-68 psi.
