Stainless Steel HPX - Ford 7.3L Powerstroke (94-97)
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 to flow to the opposite head, the issue of pressure spikes are less and allow for a smoother idle. We manufacture our own SS HPX lines right here in the USA unlike many companies today that outsource their product lines.

Quality product
I honestly thought that this item was witches brew, but I got it to try and lo and behold it works! Idle is smoother, 7.3 in my 97 is way quieter...great product!

Stainless Hpx
I replaced my leaky high pressure rubber hose with this well made stainless HPX. Fit perfectly!

1997 Powerstroke
Smoother idle for sure, much more than I anticipated from this quick and easy install. Motor seems to run just a bit smoother in general. Every Powerstroke should have this modification.

Well made, fits perfectly
I put this in my 95 F250 while I was replacing my HPOP lines. The line and fittings are high quality, my truck seems quieter and has a smoother idle. No leaks after about a month of use, I would recommend this part.

HPX line
I put this on my 96 7.3 Powerstroke, easy install. I don’t have a torque wrench so I just snugged it down. Runs really good and the motor is a lot quieter at idle and my RMPs are lower than they used to be.

SS HPX
Installation was easy and straightforward, I didn’t have to bend the part to make it fit. Take your time and tighten everything down. I personally can’t hear it, but my wife says the truck idles quieter.

Theory makes sense
Seems to quiet the engine down some. Makes sense to balance and equalize the oil between the heads. The fit was perfect and quality part. I don’t think it’s necessary, but i nice to have.

Love this company still!! Thank you guys
It didn’t really fit, it seem too long n as if the bends on the pipe weren’t right so I had to force it on the fittings. My truck never leaked before but now it does but I don’t see any oil leaks from the fittings.
