Especially when you're replacing your HPOP, there's no better time to replace the lines for increased durability and reliability plus add an HPX kit for more balanced oil flow. These replacement hoses are built from high quality Aeroquip hoses, featuring Dupont Teflon lining and also feature an increase in diameter to 3/8" for unrestricted oil flow.

These lines are to replace the typical high mileage expensive OEM HPOP lines. Kit comes with two hoses and all of the necessary fittings. Hoses are up-sized to 3/8" featuring top-of-the-line Aeroquip hose utilizing DuPont teflon-lining with a burst pressure rating of 16,000psi and working temperature rating of 400 degrees Fahrenheit. Nominal working pressure is 5000psi at 72 degrees and 3000psi at 400 degrees.

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.

Much quieter idle
Would definitely reccomend these lines for anyone looking to upgrade their factory quick disconnect lines. installation was easy, just follow the detailed instructions. Put a dab of vaseline on the O-rings before threading the new fittings in, and just like the instructions say, use green sleeve retaining Loc-Tite to secure the HPOP fittings. The factory HPOP line springs come out easy with a small magnet.truck runs and idles way quieter.

Stopping Oil Leaks
Upon purchasing this item I was somewhat skeptical about the performance, and benefit of these oil lines. #1. installation was very east, with outstanding fittings designed, and supplied. #2. the fitment was suberb.#3. performance enhanced, with decibel levels reduced. I highly recommend these oil lines for a enhanced performance, with durability to follow.

Great upgrade for the PSD 7.3
Make the power stroke 7.3 run stronger, longer, and quieter? Count me in. Easy install, and clean look.

Would definitely buy again!
Worth every penny! Installed them on my '95 Powerstroke and after driving it for about an hour to get all the air out, the truck runs soooooo much smoother. That cross over line makes a world of difference! Very well made lines and no complaints after about 1000 miles of driving. Very satisfied customer.

Thanks so much for the great review. The crossover line really makes a difference in balancing everything that you can notice even from a seat of the pants feel. Thanks again.

Great product
Install was easy and made the truck idle smoother. Dealer wanted 140 just for one hose so why not replace the lines and do the crossover!

Does this kit eliminate the quick connect fittings or do you still use them?

Eliminates them.

Why remove the spring checks? Could this potentially cause back pressure on the pump?

CNC fabrication removes it as its a useless restriction. Oil bleed back would only occur if there was an additional leak in the HPOP system such as a cup.-TL

Can I use the hpop lines you sell and remove the spring check with all stock injectors? Will it cause any issues??

Yes you remove the spring checks when installing those lines. It will not cause any issues. DppSands

Are these the correct lines for my 95 7.3??

No, these lines are intended for the 99-03 7.3 Powerstroke engines. You would need PN: CNC-OBS-HPOP-LINE-W_HPX which are for the 94-97 7.3 Powerstroke engine. -Ben
