Works great but a year later and I have to replace the prongs on it because they started leaking

Easy to install. Quality part. Great price. Highly recommend Riffraff Diesel.

fit was perfect and install was simple
definitely made a difference in the injector noise
first tank through i got almost 1 mile per gallon better
why Ford didnt put crossovers in stock escapes me
made in America would have got the extra star

Installed the HPX while changing the HPOP orings out and cleaning up the boots and valley. There is a very noticeable difference in the noise and smoothness of idle.

I guess I didnt tighten them enough and they leaked, one side note than the other. I was surprised how much I needed to tighten the line fittings. Once I got them tightened down and running it is much more quieter like others have said. My son even noticed in a 5 sec video. He is probably going to buy one too.

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.

love the ease to install

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

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)
