low steering pressure

[dayj1]

That's an EVO fitting which I think stands for "Electronically Variable Orifice". It was an option in '02 and even the previous generation of C/K trucks. I think it was called Magnasteer back then. At any rate, I've just seen some information about them in passing and I'm not sure how the system works. You could probably Google up all you want to know about them now that you know what they're called. I'd take ls1nova71's advice and replace the EVO fitting with a standard high pressure pump fitting.
