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

    Good quality. However, I’m not sure it is worth the hassle as I noticed no change in my trucks running quality (it doesn’t have any mechanical problems I’m trying to mask)

    HPX crossover line

    I just learned about this crossover line that didn't come factory. It makes perfect sense. This is another quality product from Riff Raff that is very easy to install.

    100 miles in. Works as should, didn't notice much of a difference, however the idea of the product is a nice thought.

    Easy install. Perfect fit. A definite difference in the idle quality and noise level. Another great product from RiffRaff!

    Must do

    Posted by O Man on Apr 26th 2023

    Can't go wrong with the suggestions from riffraff on what products are a must for building a reliable 7.3. Seemed to run smoother and along with the fuel crossover and SS fuel lines it really woke the truck up.
