7.3 hpop crossover oil rail plug thread size?
 

i am want to make a hpop x-over hose. what size are the plugs? If i know what size the plug is I can get an adapter to fit my hp hose.

#5 ORB fitting is the only thing I can come up with.

any help would be appreciated

is this the right adapter for the head to a -an 6 for me to make the crossover pipe.

From what I've seen, that's what you need 5orb to 6an adapters, 14" of HP steel reinforced hose rated for minimum 5K psi, and 45 degree 6an hose ends. Do NOT use JIC fittings, AN and JIC are technically interchangeable, but the thread of AN fittings are held to a tighter standard and have more cross sectional area to the thread, I use JIC adapters with AN hose ends all the time, for FUEL >100 psi, at 2k+ in the oil rail your going to blow the threads out of a JIC. Watch out for Napa doing you like that, find a Aeroquip dealer, little more money, but they do amazing work on HP hoses like this. The adapters are around 6 each, the hose should be around 35-40.

For a discussion of AN vs. JIC look here, great and clear info on the 2.

sweet! I searched and searched and never could find a definate answer from anyone that had done the DIY HPOPX hose themselves. THanks

hose length
 

Is that total length? or is it length including the 45* fittings?

Not sure, I went back thru bookmarks and the page that had the DIY x-over has been removed from the website.

what does this mod do? i've never heard of this,

suppose to bridge the pass./driver oil rails to equalize pressure. since you only have one hp oil sensor.

High Pressure Oil Crossover Hose Kit 1994-2003 7.3L

This hose is used to bridge the 2 high pressure oil rails in the heads that feed the injectors.
The installation of this hose will typically smooth out rough idles as the ICP can now sense the pressure in both heads, quiet the engine, as well as provide improved oil flow to the injectors.
