HPX crossover?

I was looking on RiffRaff and I see they have a High Psi crossover pipe is this mod worth doing? Seems like a good idea...

I did it, I too think it's makes sense to end the "dead-head" fuel rail (think of how easily you'll be able to restart if you ever ran out of fuel )

The only people who I've seen object to it are those who already spent $600-800 on the "old school" Regulated Return...

You are talking about two different things. The second post is about the Frx. The Hpx connects the two heads for oil. I did it and honestly I don't know that I could really tell any difference. Doesn't mean it isn't doing something just nothing I could audibly hear or physically feel.

hehehe... You're absolutely right! I was thinking FRX

To the OP however, I have the HPX too! And kinda for some of the same reasons (ending the "dead-head" in the HP oil system)

"The Riffraff Fuel Rail Crossover was made to solve the 'deadhead' fuel rail issue on the 99-03 Powerstroke engine. By connecting the two heads and allowing a metered return you allow the air another return path, rather than forcing it through your injectors"

If it did anything, I could NOT tell.

I did the HPX and where I really noticed it was cold starts and it is slightly quieter For 55 bucks, it is a worth it mod IMHO.
