7.3 Oil Crossover
Installed the HPX, FRX, banjo bolts and SS fuel feed lines on my 2001 F250 with 7.3 a couple of weeks ago. Not sure on fuel mileage improvements yet, however, I do think it runs a bit smoother and quieted it down some. This is not my daily driver so haven't even put a full tank of fuel thru it so not alot of feed back at the time.

Quality looks good and fit perfect. Zero leaks, very happy with it.

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
Perfect fit and finish like all of RiffRaff parts

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.

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