Thanks everyone for helping. Especially Earl for being right.
I'm not sure how my mechanic checked the "o" ring. However talented they are, they can be pretty lazy about some things. But, since I bring my car their and have gotten them tons of business they barely charge me. So he coulda just glanced over it. I'll look over my pump and try to maybe overhaul it myself(break it but learn from it) and then probably replace it . I guess it'd be too tough for me to upgrade on my own, and since I own an SVX and am in college I dont have enough cash to pay my mechanic for a job like that.
