Love this oil line helped smooth out my idle and gain a little bit of power

Owned my truck for 19 years now. Has almost half a million miles on it and since I got it the injector rattle/ clatter has always been loud. This cross over line is a must for any 7.3 owner. I have referred 3 others and they all got one and they think the same. After 10-15 miles or running the injectors rattle/ clatter has gone away, engine runs smother and much quieter .

Perfect fit

The truck running good

If you;re working on your trubo/pedestal that's the perfect time to add this gem, perfect fit and very easy install.

Being newer to the diesel community I have done a significant amount of research into maintaining my 7.3. RiffRaff has made it easy to order, quickly receive and provide excellent products. The oil crossover tube fit perfectly. Completely happy with.

This crossover tube is a super easy install; maybe 15 minutes with the right tools and you don’t have to remove anything. This tube drastically stills the violent V8 vibration of the engine. I have noticed a much more consistent and quieter idle rpm’s. No more loud injector noise. I could be mistaken, but I have noticed a slight increase to acceleration response from this crossover. One of the best longevity and reliability mods to a 7.3 money can buy in my honest opinion. This tube comes with two adapters with o rings that replace the block bolts that sit flush against the block. Make sure not to over-tighten and hold them still when adding the compression tube.

7.3s are loud, but it made it noticeably quieter and smoothed out on acceleration. Easy and worthwhile upgrade. My wife even noticed this upgrades benefits.
Do it,

I have installed the HPX on two different 7.3 trucks and it was easy to install and worked perfect with no leaks both times. It quiets the engine down significantly and provides a smoother running and idling engine. Highly recommend!
