regulated return

hey guys I have a question about my 6.0 fuel system. performance wise I don't think I need a regulated return system for my truck but I was wondering if you could plum up something where its not a dead head system. I want to install the blue spring kit and the 6.4 banjo bolts. Any info would help.

Check out the driven diesel setup, I think it's the best one out there. Plenty of guys build there own, lots of threads on it. I think it's important for healthy injectors as much as performance.

There is no way to do a return off the back of the heads without a regulator. You have to have something there to keep the pressure up. The dead head system actually works pretty well. My fuel system is regulated before the heads like the stock setup but after the heads I essentially have a remote dead head with a second pressure gauge there. There is no difference in pressure in front of the heads or after them.

For stock trucks feeding the injectors clean, water free, air free fuel at the right pressure is the most important thing. Consider starting at the source of the fuel first for spending good money. A blue spring kit should cover you up top for now. Add a gauge to see what the whole system is doing.

Putting any Airdog on your truck would be the biggest mistake you could make in a fuel system mod. Just do a search. They just won't hold up on our trucks and Pure Flow has known it for years. Just ask any of us who went through multiple failures and problems.

I agree with Mitch here. The airdog2 has more failures than I can count. On the other hand I have an airdog 150 since 2010 and no issues to date. No clue why

But with all the new stuff out on the market with fuel lab and aeromotive I'd honestly try getting one of those. Truck source diesel has these I believe.

Also dale a sr ford tech on here has write ups and information for 6.7 fuel pumps that may benefit your needs

I too have had an Airdog 150 on my truck for over two years without a single hick-up. I agree that the Airdog 2/165 is a POS and while Pure Flow has known it and not addressed it is unsatisfactory, but the Airdog 100/150s have been proven to be pretty much bullet proof in my experience.

I have run air dog 2 & Fass lift pumps and had troubles with both. I now run an A1000 pump with fuel/water Sep filters and filter base from NAPA. Not a single prob with it. Holds psi extremely well also under WOT

This is what I did as well. An A1000 with napa bases and CAT filters. But to answer your question... I think that you can run a healthy stock fuel system and never have a problem with injectors up 175's and I heard even 190's but I personally had it work well with my old 175's. I ran the stock fuel system for 100k and never lost an injector and just think of the 1000's of trucks out there running it with no problems. If you have stock injectors... it is my "opinion" to keep fresh factory Motorcraft filters in it and run it.
