Over the years we’ve read online comments or been asked why our fuel system kits are more expensive than some of the others on the market. We have needed to put this in writing for a long time, just to save us the time typing or answering it over and over again. There are a number of reasons why our product might be more expensive than someone else, the list below shows the biggest reasons.
Trial and error are a fine way to figure some things out, we’ve all done it that way at some point. That’s pretty much how the 7.3L/6.0L Powerstroke aftermarket has figured out what fuel pumps will support what injectors for years, for a number of reasons.
Before I get into the discussion about the different configurations, I want to emphasize a point that I started to make in the previous article. I pointed out the fact that the 94-97 OEM fuel system is a REGULATED RETURN, and that the 99-03 OEM fuel system is a REGULATED SUPPLY. I make this distinction based entirely on the placement of the fuel pressure regulator in the system, and whether it is regulating the pressure BEFORE the fuel rails/injectors, or AFTER.
