AA scales sells some inexpensive kits, for under $500 and an afternoon of work you can assemble one to for your need. So far mine works great, we will see how long it holds up.
I had a similar problem with my 4044. I ended up pulling the tank and cleaning the strainer in it. It gets coated with black tar like stuff. If you just blow thru the lines it’s only a temp fix until the sediment covers the strainer again.
