HPX question
What size plug is that on the heads and what is the working psi there? Thinking about fabbing up a braided hose for this while I'm ordering my fuel return items.

This topic has been gone over many times. I believe it is as high as 3000 psi. It's something that you probably wouldn't want to fab up on your own. A hydraulic shop may make one for you, but even then there are numerous reports of the hose fittings starting to leak. The solid stainless line is the only way to go.

Actually I've been researching building my own SS HPX. There have several guys over at TDS fab their own SS line.
You should be able to have a braided hose line made that is as good as any of the available flex lines for a lot less money.
The fitting into the high pressure galley is 1/2" 20 tpi striaight thread O-ring fitting from what I've read. The workng pressure in a good pump is 2-3k psi range.

You can build your own SS HPX solid line. I would highly recommend against building a braided line. Not only must the line be able to deal with high pressure (3,000+ PSI) but high temperature as well (remember - this line may only carry oil at 200+ degrees, but it sits in the engine valley underneath the turbocharger).
I have a braided line I bought from Tymar - easily the best flexible HPX I've seen. However, if it ever fails, I will replace it with a solid line. If the solid HPX had been available when I bought my Tymar, I would have bought the solid.
A mistake in making this line will result in quick and messy oil loss - and the engine will quit running pretty quickly, too.
