In 32 years of diesel reapirs I have never had a reason to dislike the vibra lock set up. They are pretty standard fuel and water line fittings in the industry. I plan to run the fuel in the front of the heads and out of the rear through the original vibra lock fittings to a hard line to the Y. Gotta remember to leave the old fuel pump hole clear so if(when) I get to a T4 turbo set up I wont have to rework it to be able to use the old fuel pump hole for an oil drain.
The reason to flow it this way is the already heated fuel will be passing the hot up pipes, not the fuel we want to be cool and dense going in.
On the vibra locks, the correct grommet for them will seem like it is one size too small and takes a lot of streaching to get over the tube. And no, a cut off piece of hose will not work except in an emergency. Heck I've used string in an emergency!
