Thought the fuel filter was going to be harder than it was. Watched a YT video on it, saw his mistakes and decided to modify the process. In the video he talked about doing it by the book and the book said to undo the sensor harness, then remove the bottom connector from the filter and drain it first. He also did not crimp the fuel line until much later. So first, I gently crimped the line with a woodworking squeeze clamp I had [padded one so as not to damage the line itself]. So as not to create a huge mess, I then disconnected the sensor harness but left the bottom filter connection attached. Then I unscrewed the filter by hand. Only got a few drips of fuel doing it this way instead of bathing everything below in diesel.
Then, I emptied the filter into a clean can. Once the sensor harness was removed, it was installed on the new filter. For some reason they no longer have the clear bottom part, btw. Then after screening the fuel just to make sure nothing got in it, I poured it into the new filter. I know there's a hand pump up top on the filter housing, but it wasn't used.
Once everything was back in place, I turned the key to run and held it there for a couple of seconds, then off, then back to run again for another couple of seconds. Started right up and ran perfectly from there. Let it run for a couple of minutes to make sure all was good.
Before all this, I had changed out the engine oil and filter, changed the air filter and the HST filter.
