2003 – 2007 6.0L Trucks (Not Vans)
If you are a 6.0L enthusiast, this is one of the most exciting developments to come along in some time. Finally, a way to quickly and easily adjust fuel pressure to exactly where you want it in seconds!
No more need for trial and error, no need to take the pressure regulator housing on and off multiple times while you experiment with blue springs, stretching springs, cutting springs, installing BB’s, etc! Now you can tune your fuel pressure to match the requirements of your vehicle and overall package of performance modifications such as performance injectors or an aftermarket fuel pump system at a fraction of the cost of a regulated return system. Quickly tweak your fuel pressure for testing purposes, or change it for various activities – for example, you could raise the pressure for a trip to the sled pulling contest and lower it back down for the drive to the grocery store!
6.0L performance enthusiasts have long been aware that fuel pressure plays a big role in how their engine and fuel injectors perform. Pressure that is too low can very quickly damage an expensive set of injectors. While installing a blue spring is a step in the right direction, it does not guarantee an exact pressure, which will vary with pump output, injector size etc. Additionally, all springs will loose tension over time, gradually causing pressure to drop. During the research phase of developing this product, the inventor found that the trucks used in testing ran very well at 65 PSI. Engine operation was notably quieter with better power output.
The 6.0L adjustable fuel pressure regulator housing is a work of art, CNC machined from a single piece of aluminum, and comes with a beautiful anodized finish in red, silver or blue to show off your modification and dress up your engine compartment. The pressure adjustment screw / shaft features a double o-ring seal design to prevent the possibility of any fuel leaks and is made from stainless steel to prevent corrosion. A new “key-hole” gasket is included installed on every unit.
