theres a plastic drain valve on the filter bowl...it is a common place to find a leak. Theres two 0 rings that fail inside it. Easy to replace for 50 bucks from Ford or maybe NAPA carries the vave cheaper.

2000 7.3 Excursion also on a high cholesterol fuel

If it's leaking out the drain tube or from the valve, that's probably it.

Here's how it's fixed on the '99-03, should be the same O-rings?

Re: something to check

Look on top of the motor around the rear of the water seperator and fuel pump, look for pooling of fuel. If it's has some then it might be the fuel pump. As you will find there are many threads on this topic
