Welcome to FTE, purepork.
Sounds like your o-rings may be giving out on the drain valve, which wouldn't be odd given the vintage of your truck. The valve isn't supposed to act like a relief valve at all, just there to drain water out of bowl or drain fuel before changing the filter.
The link below lists the part number for the fuel filter drain kit (about half way down the page under PowerStroke parts).

The link below details the repair process for these o-rings, if they are the culprit.

We have had a ration of fuel drain valve failures lately.
There are two little o-rings in the yellow valve that seem to be going bad, either as a result of age, or maybe the new ultra-low sulpher fuel formulation.
The o-rings are easily and cheaply replaced if you want to do it yourself, or you can get "bent over" and have Ford do it for you. Depends on how handy, or weathly, you are.

Welcome to FTE. How do you know it has only done it 3 times? If it is coming from the drain vavle and the valve is in a closed posistion, then your o-rings are leaking and need to be replaced. I would suspect that it has leaked more and just not noticed. The drain valve is not susposed to be a relief valve when o-rings are working correctly.
EDIT- Man, got to learn to type faster.
