Advanced HPOP lines with DuPont Teflon lining.

Nominal working pressure is 5000psi @ 72*F and 3000psi @ 400*F
Kit comes with Genuine Parker Triplelok fittings
High quality Viton o-rings 
MADE IN THE USA

The HPx line connects the two heads to help balance the high pressure oil system in each head. It does not create more horsepower, but the majority of owners see a slight to significant decrease in engine idle noise. This is due to the helmholtz resonance that is created from the injectors firing so quickly, and the HPOP cannot react quick enough to balance/absorb on its own from back pressure spikes within the system. So when the tiny spikes happen, the HPx line sends the pressure back and forth through the heads instead of hammering on the pump itself.

INSTALLATION: Disconnect the battery grounds before installation to avoid accidentally arc'ing the line on the glow plug relay or the alternator charging lug. Use the pictures on this page for reference. The lines are marked "PA" for passenger head and "DR" for driver head. After installation, be sure there is no other lines/wires that are touching the lines that could potentially rub through and damage either the hpop line or the other line that may be touching it. Use a small section of wire loom protector or a larger piece or rubber hose to wrap around the contact point. Although it is not necessary as there is room on the driver side, but the eyelet for engine removal may need to be slightly bent in using a large pry-bar through the eyelet hole bending it towards the fuel bowl. Do not use any thread sealant on any of the fittings, except on the pump. IF you choose to use any, use Loctite 680 or 620 retaining compound (green), but it is not necessary. 

These lines will route different than OEM. Driver side will route just like the 99-03 models. Which means it will now route to the second oil galley port and go around the engine lifting eyelet. The passenger side line will arch slightly over the front fuel bowl lid. This will not hinder the removal of the fuel filter. The HPX line will route just like the 99-03 trucks also (which is the third set of oil galley ports back starting from the front of the vehicle) picture of the lines installed will be coming. If you are unsure of installing yourself, seek out a competent and qualified technician to install the lines.
