It's every 30k you need to replace your tranny oil. I would be a little cautious about a shop that says you don't need it but every 100k. For a car maybe, but not for a truck that is expected to be hauling stuff and hitting some pretty good temps while hauling.

Keep in mind that any water that MAY be in the HFCM housing will drain out first in the first few seconds... as oil (fuel) floats on top of water. The HFCM drain is the single lowest point of the fuel system.. and where water will collect. I would drain for no more than 1 minute to ensure all flows out then just shut it off.
Remove filter cap and replace the HFCM filter as required. My dealer tech told me that changing the filter does not remove or drain any water in the HFCM... so always drain first, then do the filter change.
