Regulated Return Kit for Your Diesel

When it comes to Upgraded Performance Parts for your 2003.5-2007 Ford Power Stroke, there are a lot of different manufacturers out there making some excellent products. Sinister Diesel Performance makes some excellent products that we find ourselves using here in our shop daily.

Their regulated return system for the 6.0L is not only a good choice for people looking to make horse power. It is also an excellent product for customers driving their trucks to work daily. It will keep even pressure across all 8 injectors which will increase injector life.

We replace a lot of 6.0 powerstroke injectors here at the shop and we have started installing the Sinister Diesel regulated return kit to save our customers some money. We look at this kit as a cheap insurance policy and our customers agree. It’s much more affordable to install a regulated return kit and a couple of injectors at the same time than it is to replace a couple of injectors every couple of months. Not only will you save money on parts, but also the labor involved in tearing the engine down every time to replace injectors.

Regulated Return


The factory fuel system on a 6.0 Power Stroke naturally starves half of the injectors for fuel, it’s a flaw in the factory design. The Sinister Regulated Return kit evenly pressurizes all of the 6.0 powerstroke injectors, when all 8 injectors are holding even fuel pressure they are going to live a much happier life.

For the best results we recommend a FASS Titanium fuel pump to go with the regulated return system. This will keep unwanted air and dirt from getting through your new injectors and the regulator.

Sinister makes more than just the regulated return kit for your 6.0L Power Stroke. Look for more reviews on their Coolant Filtration kits, external oil filters and upgraded EGR coolers.
