So Tex & Kep was it a bad product or just a bad company? I did a back search on here and only found a couple of posts about the crossover line but nothing bad. I tried the link to LIPD but no longer available.
Was this just a trial item and didnt do well? Now the market is for RR kits? My truck is still in warranty & dont think dealer would help out if I did a full RR kit, but if just a crossover he may see the benfits & still help me when needed.

The only challenge is to find AN fittings with the same thread that is in the head where the plugs are removed from.
Also, I believe you must use 90° fittings for the head due to turbo Y pipe clearance.
My FCL had banjo fittings on each end with the correct threaded bolts. That takes care of the Y pipe clearance problem.

You can get your banjo's and bolts on this page: http://www.anplumbing.com/shop/index...p=&dept=Banjos From there you simply have to pick your size and hose to attach it. The thread size in the head is 12mm x 1.5. You can either use a banjo bolt or an o-ring fitting and 6AN hose.

Thanks for the help guys. Problem is my location up in Northern Alberta, I'll walk into the parts store with this list and they'll stand around scratching various body parts and say they never heard of such things.
Thats why I like to buy a kit and install. I love saving money and do-it yourself projects but just cant come across most materials to do so.

That's not something you want to do. The system would never pressurize correctly and the pump could never keep up. You would have virtually no fuel pressure at all

I just don't see a whole lot of benefit to a simple cross over line, since the system still remains a "dead end".

And then you have a regulated return system. The point of the crossover line was to balance the fuel from head to head. At some point the air will work it's way out throuth the injectors anyway.

As I said in a previous post, I believe installing a drain valve in the FCL would be benefical. Then when the fuel filters are changed, open the valve, turn the fuel pump on without starting the engine and purge all of the air out of the fuel system before starting the motor. Some food for thought!
Concerning a return line from the injector rails, it can be done but a little science would have to be employed. A restrictor would have to be engineered and placed in the line to only allow a very small amount of fuel to continuously return to the fuel tank or, as NPCCPARTSMAN said, the fuel pump would never keep up with the fuel flow demand and the motor would probably not run or significantly miss. Just MHO!
