If so, what is it?
So much armchair speculation in such a short amount of time! Rod bearing failures from low fuel rack pressures? Wow! Someone better get a hold of the Cummins and Caterpillar guys since their pumps use the exact same spring valve design and see if they're having rod bearing failures too! Flame me if you want, but with claims that low fuel pressure causes rod bearing failures, I want to see some damn data to back up that bold claim.

Seriously though, if it took 30+ years for the spring to fatigue, it's going to take that long to fatigue again. If you really think your car is going to make it to 70 years old as a daily driver and never ever want to worry about it again, swap out to the 60x "new" style banjo bolt. They rely on a drilled orifice, not a spring acting on a ball.
