These lines are to replace the typical high mileage expensive leaky OEM HPOP lines that have the STC fittings. Kit comes with passenger, driver, and crossover hoses along with all necessary fittings to eliminate the quick connect fittings (STC) on the heads and the HPOP itself.

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 pictures from the product webpage for routing example. The fittings are marked with numbers to label install location (see below for reference). 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.  Many will remove or bend the engine eyelet on the driver side as a precaution, but it is not necessary.  Sealant is not necessary, but IF you choose to use any, use Loctite 680 or Permatex 64000 retaining compound (green) only on the fittings installed in the HPOP.  If you are unsure of installing yourself, seek out a competent and qualified technician to install the lines.

NOTICE:

We know it may be cheaper for those wanting to save some money and have a local hydraulic shop make lines, but in our 20yrs experience, it is not advisable due to the amount of thermal cycling and engine sees.  Normal hydraulic is meant for normal hydraulic use, NOT on the engines. See pictures of what happens to our competitor lines. Dry rot and blistering of the hose. We have sold over 10,000 kits.
