I didn’t want to start a new post- but wanted to add this for newer members who aren’t familiar with the Hutch Mod just as I wasn’t. I believe this “reply” information I’ve edited from strictly diesel is very interesting. I did edit out the original OP’s name so as not to offend anyone:
The hutch mod was NOT developed as a "filter" setup. From day 1, when Mark Hutchinson released his findings from some testing he did (way back in the early days on Ford-Diesel.com which is now TheDieselStop.com), it was about engine noise, poor fuel economy and air in diesel fuel. There were a BUNCH of us working diligently on different aspects of the fuel system in 7.3L trucks back then. The main players were Mark Hutchison, myself, David Lott at Diesel Innovations, Bob Riley at DieselSite and a handful of individual truck owners. Mark got curious one day and installed a clear hose from the tank to the pump, and from the pump to the engine. What he saw was a crapload of air where it shouldn't be. He dropped the tank, got rid of the mixing chamber and got rid of the quick disconnect fittings and found that a HUGE amount of the air he was seeing in the hoses disappeared as well. It made a noticeable difference in the noise the engine made and as the rest of us tested his theories in our own vehicles and proved the concept, "hutch mod" kits were born. For years, while he was still active in the diesel community, Mark actively referred people to us because he liked how we laid out our kit. It wasn't about being the least expensive for us, it was about "doing it right". We used a spin-on filter instead of an inline because we saw air release with the inline filters. We made our brackets from S.S., used pushlok fittings and AN fittings for joint serviceability where possible, used top quality hose, etc.
In a nutshell, getting rid of the quick disconnects (the OE connectors you referred to) is one of the biggest reasons people actually do the "hutch mod". It's also the reason we perform the pain in the butt step of pushing the hose over the QD locking ridge on the tube, to make sure that the hose is 100% sealed against the tube and not letting any air in.
