High Pressure Crossover Hose?

Does this really make a difference in the quieting the motor noise?

I installed one on my 7.3 and at 50mph+ it has made a considerable differance with the engine noise. I don't really notice a big differance at lower speeds or while idling. However I did manage to blow both the o rings that came with the kit I ordered from strictlydiesel.com. I replaced them with ford o rings and have not had trouble since.

Yes it can quiet the engine. I put the crossover on both of the last 2 7.3 trucks I've had and it helped. Idle noise was lowered alot on my 99. My 01 was quieted down a little bit. Both of mine came from ITP Diesel and I was happy with the fit and finish of both.

I didn't really notice any difference for sound, BUT:

It makes the rails have even pressure, allowing the ICP to read both rails, and allows for better oil flow/pressure to the #8 cylinder.... helping it NOT run lean. (Not burn up the cylinder or the injector.) I think mine was $60 ish, I got the braided stainless steel line made by Tymar Performance.

I know CT Performance/Carey has them.

Mine definitely quieted down the engine.

What ToMang07 said! I bought Riffraff solid line stainless steel HPX. I may have noticed a little difference, but I know the two oil banks have been equalized!

Mine idles a little smoother but noise level isn't that noticeable. But... cold morning starts is where I noticed the most difference. Being in Texas not really sure if it would get cold enough to notice. I'm talking below 35 degrees.
