High Pressure Crossover mod

I was interested in installing the ITP HPX SSS line, but is it worth it? What are the benefits? And for $70, I can make my own (I'm a hydraulic mech

) anybody got dimensions for the darn thing?

It wasn't a huge difference - but worth it, IMHO.

Will run like crap for a while, but seems a lot better now. That happens when you introduce air into the high press oil system. If I were you Marine, I'd make my own. Can't remember the specs on the fitting though. It does seal with the Oring and not torque, or a taper type npt fitting.

It's a #5 o-ring boss fitting if I recall correctly.

I think it's one of the best mods I did. At first, the HPX cross-over caused a little more "rocking" type vibration at idle, but not any more. I have no idea how it worked itself out, but it did.

No vibration at all at idle now and she just seems to be soooooo much smoother.

Man, I love this truck.
