Stainless Steel HPX for Ford 7.3L 99-03
The Stainless Steel High Pressure Crossover is meant to allow excess oil pressure to flow between both heads allowing for better supply to the injectors. By allowing the oil the flow to the opposite head, the issue of pressure spikes are less.
HPx line comes with adapters, ready to install.

Cross over fuel line
Was skeptical about this making a difference but after installing it I’m a believer smoother running idle sounds solid definitely buy if you don’t have one

7.3 HPX
This is a great product from Riffraff. Installation was very straightforward. The tube was shaped perfectly and the instructions were very clear. I did not remove any of my CAC pipes or spider and was able to reach both fittings just fine with standard wrenches. Follow their torque specs and do not exceed them. I did notice a smoother idle after installing the HPX. The most notable change was in the exhaust sound at idle. My 5” straight pipe used to be “choppy” at idle and is now much smoother. I definitely recommend the HPX.

Quality!
Fast shipping and great quality. My truck idle so much quieter. Nice to have a balance in oil pressure. Smooth running too.

High Pressure Oil Crossover
Easy to install. Oil pressure seems more stabilized which makes the engine run better and quieter. Pair this up with the FRx kit and you'll be very pleased with the response from the engine. Wish I'd done this a long time ago.

Heavy duty, perfect fit quality product
Took a few extra minutes while installing new glow plugs in my early 99 f 250 SD 7.3 4x4 to add this new HPX cross over line. Took 5 minutes and fit perfectly
