He put a plastic drip tray under the filter, and when unscrewed there was some fuel leakage, bot not a great deal (maybe 1 1/2 cups or so), but that was it. Also, I always thought that the plastic fuel separator was replaced also .... but not so. Its a pretty substantial thing, with internal heating element. He used the wrench to loosen the plastic separator first before spinning off the filter itself. When taken off, the fuel in the filter got dumped into the plastic drip tray .... and then the rest of it was a rather calm affair of putting the water separator on to the new filter, then putting the filter onto the rig. Hand tight he said, do not use a wrench. definitely lubricate the o rings with fuel (or other) before placing the filter and separator together.
Turns out my rig does not have a lift pump .... so prefilling the filter is mandatory. We discussed options, and he had no problem at all with using Howes diesel treat to do that. He also said that his father, a farmer, absolutely swore by Howes .... so it would not hurt at all to just carry a bottle of Howes and use it for fill ups ..... and coincidentally also then have something to prefill the filter and lubricate the orings with. I feel much more confident about doing that swap on the road myself should the need arise....
