Fuel Starvation Issue

I was having fuel starvation issues at all speeds. Found that my new gas tank had dumped a bunch of gunk into both filters. Now that I have cleaned both filters I am still getting a starvation issue at Hwy speeds when I give it WOT. I'm thinking the pump may have gunk in it. Thoughts? Is this pump even good enough for a 670HP engine? Maybe electric would be better?
