I am seeking advice on the progress I have made working on my fuel issues.

First trip out for the year the boat ran well for approximately an hour. After restarting and attempting to run, the fuel pump began to whine and I could not exceed 3000 rpms. When I would slow down to 1500 rpms, the pump whined for a bit, then stopped. I could then run WOT for about 5 minutes. Then the problem came back. The boat shop said I had water in the fuel. Recommended dumping the fuel filter a couple of times to remove the water. I tried this and it seemed to help, but the problem would come back sooner or later.
Once we were back home I did a lot of research. Lots of info related to black paint pieces in the fuel cell. I checked the under side of the fuel filter housing and it was falling apart. Also, this time there were large chucks of black plastic or rubber in the fuel filter. I assumed it might be an old gasket that someone left on. But, after reading a post on the paint issue I have decided it is the paint from the filter housing. So I cleaned all the paint that was coming off the housing, I also installed a new filter.
On a side note, this boat has always been sluggish off the line. It pulls much slower than other boats with the same engine. WOT there are no issues. I read somewhere that there is an issue with the fuel regulator filter and it should be replaced with an eclip. When I took off the regulator, the filter was 80% clogged with the black paint pieces. Lake tested the eclip and the results were astounding. The boat pulls much better down low and it's much quicker getting on plane. So, end result of the eclip was good.
Back to the fuel pump issue. When I lake tested it this time, I still had issues with the pump whining. I didn't want to keep taking off the filter and dumping it. One because I was in open water and didn't want to dump in the lake. Two, I remember reading something one of the mods posted about not dumping the filter because it can cross contaminate or something like that. I decided that the first thing would be to let out the pressure from the valve on the fuel rail. When I did this, it shot fuel spray and air out. I thought it was strange to have so much air in the line. I primed the fuel a few times and did it again. Half the air this time. About three or four more times there was only fuel coming out. I started the boat up and presto, no more fuel pump whine and I had full range of the rpms for extended periods of time.
My thoughts now are is this a temporary fix? Will I still get issues with these paint pieces? Should I pull the injectors and clean the filters on those? Does the low pressure pump have any filters like the fuel rail did? If so, where is it located? Any other advice would be appreciated.
