Description

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.

  • All new Genuine Brennan™ fittings 
  • DuPont Teflon™ lining just like OEM
  • Burst pressure rating of 16,000psi
  • Working temperature rating of 400*F
  • Nominal working pressure is 5000psi
  • High quality Viton™ o-rings
  • MADE IN THE USA IN OUR SHOP

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 match installation location (see below for reference). After installation, be sure there are 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.

Just installed this kit on my 2000 7.3, great quality lines and piece of mind to replace the problem prone STC fittings. Completely doable with a couple of wrenches and some patience, no special tools required. All quality stainless lines and fittings so I’m sure these will last another 18 years. I also agree with the discription on quieting the idle noice and I think the truck runs a tad bit smoother.

These are nice quality lines, too bad I can't use them! The head ends hit my aftermarket intake plenums that are a bit thicker than stock. $200 wasted. Wish that was posted on here somewhere...

I just installed these on my 2002 F250. The installation process was very easy, but do yourself a favor and get the correct tool to remove the quick connects on the old lines. I fought with mine for a while using various tools and finally got them off. After that the rest was a breeze. Everything included in the kit seems very high quality and the instructions seemed very clear to me. The truck does seem to idle a little quieter and run a little smoother too. It’s worth the peace of mind to not have to worry about the 20 year old lines rupturing now.

Possibly the best HPOP lines in the market. High quality hoses (stay away from low cost lines made of standard hydraulic lines - they WILL fail).
CNC Fab lines DO clear the Beans Diesel Plenums I installed.
No leaks and could not be happier!
