The DI kit does get rid of the quick connects.. Here's what the kit includes in a nutshell... you get a compression fitting and an extra piece of stainless tube for the removal of the mixing valve, two pieces of rubber fuel hose for the removal of the quick connects that are at the fuel tank. These pieces of rubber hose connect back to the stock stainless fuel rails that run down the frame. The only thing you do is cut the old pieces of rubber hose off with a tubing cutter. Then you cut the rubber hose that goes into the pump and replace it with the supplied filter and hose. You put all of it together with hose clamps to make sure that it is secured...
I would take pics.... but it is raining outside right now.

This one isn't convenience -- that's the Harpoon which allows a complete fill-up to the neck. This one (Hutch) is to keep air out of the fuel system. Think about what's happening here: You're sucking air into the system, pre-pump, sending it into the fuel bowl and eventually to the heads, if it makes it that far. Any air returned gets pushed back down the return line, but it's fed into the mixing chamber in the tank. That air is sucked right back up into the system. Then, then the tank gets low, it can suck even more air. I wouldn't be surprised if the truck isn't running on foam, when the tank gets low. Fixing the aerated fuel problem I would think helps the truck run better, and keeps the injectors quieter and happier, so they live a longer life. More than convenience, IMHO.

It's not called an "In-Tank Kit" it's called a "Pre-Pump Kit". Yes, that's why it comes with the necessary hose to go to the suction side of the in-line fuel pump which is out of the tank.
I guess I think getting rid of all those Ford connections to eliminate all possibilities of air intrusion and leaks is the way to go. I understand you can go out and get more hose/line and clamps. You could probably do that for the entire job too. The kit is pure convenience and from everything I've read, high quality.
Is rubber fuel hose the way to go instead of using a hard SS line?
