DieselSite High Pressure Oil Crossover Line – 7.3L Powerstroke

Improve idle quality, balance injector performance, and stabilize high-pressure oil delivery with the DieselSite High Pressure Oil Crossover Line. This upgrade connects the left and right high-pressure oil rails, allowing the PCM to monitor and balance pressure across both rails instead of relying on a single side.

By equalizing oil pressure and reducing pressure spikes, this crossover line delivers smoother idle, more consistent fueling, and improved overall engine operation.

🔥 What This Crossover Line Does:

  • Balances oil pressure between left and right HPOP rails

  • Allows the PCM to reference pressure from both rails

  • Reduces pressure spikes by acting as an accumulator

  • Improves idle quality and overall drivability

  • Promotes more even fuel distribution across injectors

🛠️ Premium DieselSite Construction:

  • High-pressure / high-temperature Teflon hose

  • Stainless steel braided outer layer

  • Anti-static discharge hose to reduce line failure

  • High-temperature abrasion-resistant wire loom sleeve included

  • OEM-style fittings for proper fit and reliability

⚙️ Engineered for Performance — Not Just Connection:

DieselSite didn’t stop at simply tying the rails together. After extensive testing with different hose sizes, they engineered an optimized internal diameter that maintains fast HPOP response.

Oversized hoses slow oil pressure response, increase crank time, and reduce high-RPM injection performance. This crossover line is sized specifically to maintain quick pressure rise while still balancing both rails — delivering the best possible performance.

⚠️ Important Notes:

  • NOT required if running an Adrenaline HPOP (pressure balancing is handled internally)

  • Do not confuse this with the high-pressure oil lines that connect directly to the HPOP

  • Typical system pressures reach 3,000 PSI

🔧 Maintenance Recommendation:

DieselSite recommends replacing this crossover line (and OEM HPOP lines) annually, especially on trucks running performance tuning. Many chips increase pressure duration and duty cycle beyond factory limits, placing additional stress on oil hoses.

🚗 Application:

  • 7.3L Powerstroke engines (excluding Adrenaline HPOP setups)

If you’re looking for smoother idle, balanced injector performance, and improved oil pressure stability, the DieselSite High Pressure Oil Crossover Line is a proven upgrade trusted by serious 7.3L owners.

Great socks for the price!
Size: 6-10, Color: Black, Size: 6-10, Color: Black
I love these socks, they are perfect no shows but the material is thick enough for toes not too go thru. The grip is perfect and keeps the sock in place all day. I would definitely order true to size as the fit was perfect. I was surprised to find these socks at the price I did, especially when I got the socks in both black and white.

Best non-slip no show sock!
Size: 6-10, Color: Black
I love these socks! I wear them mostly with my slip on vans. The are thin so your feet can breathe (I hate thick socks). They have a grip on the heal so that they don't slip off of your feet, and it actually works! My only negative about these socks would be that if you have bigger than a size 8 foot, I would not purchase them because they do run a bit small. I wear a size 7 and they fit perfectly! They do look very tiny upon unpacking, but they stretch to the according size. I would also recommend letting them air dry after washing them and not putting them in the dryer. The first pair I purchased, I made the mistake of drying them and they shrank to an unbelievably small size. I've had my second set of socks for over 4 months now and have not had any problems since Ive been air drying them. I have not encountered any problems with them tearing as other have stated. Even though these are thin socks, they seem to be made quite well in my opinion.

I buy these again and again through the years!
Size: Medium, Color: Austin Brown Assorted (6-pairs)
Love these. After a year or two I wear holes in the bottoms because I wear them so much. Worth the little bit higher price because of the fit and comfort. Love how they are truly no show

Good quality but tight on toes
Size: 6-10, Color: White/Assorted
These are great socks that stay in place, but they scrunch my toes together like crazy. My feet are normal width. When I first started wearing them I noticed my feet would ache after an hour or two.

My New Favorite Socks
Size: 6-10, Color: Halo Gray/Assorted
These have quickly become mine and my mom's favorite socks. We wear them with tennis shoes, Hey Dudes, and more. The fabric is incredibly soft and comfortable, they do not budge/fall in my shoe, and are extremely well made. I have become so attached to these socks, that I no longer want any other brand.
