Fuel pump eccentric problem

Can someone tell me what I'm doing wrong? I am putting together my 318, and when I try to tighten down the cam bolt it starts to flatten out the bowl shaped washer before it reaches proper torque. I saw torque specs from two sources, 40-45ftlbs and 50ftlbs. Are the specs too high? It's my torque wrench broken? It really doesn't feel like it's getting anywhere near even 40 before it starts to cave in the bowl shaped washer.
