What keeps fluid from leaking out of faceplate?

I bought the paper gasket along with the screen. Then I used RTV sealer on one side of the paper. But I've started using RTV alone for this sort of seal on my Yanmars. That isn't under pressure, it's just a reservoir, so any sealer that will be removable later should do.

Mine didn't need any priming, and I think that is normal.

That oil looks just like what my Vietnam rebuilt 4220 had it in when I bought it. It wasnt water, it was really fine clay particles and they would stop up the screen and the filter (mine has a $35 filter also). I flushed, drained, changed oil, cleaned the sump screen etc for months before I finally got all the crude out of the system. Used the diesel flush also as recommended here. When I removed the screen the crude would feel like slime on the screen. 4 oil changes and 3 new filters later it is clear oil again. Thankfully Hoye had a good stock of those filters. I used the Atwood JD 303 equivalent oil in mine and have not had any other issues with the pump. Now the 3 PH is jumping up and down cycling. Have to fix that one day.

I wish my filters were 35 bucks. I think they are up to 55 or so now. So I guess I can plan on not having this cleaned up for another 3 or 4 fluid changes. Bummer.

Your 1700 does not use hydraulic filters, only washable pickup screens.
