I picked up my 790r from GP Motorcycles in San Diego last week. They told me there was a pre-delivery notice to inspect and clean out tanks. They said 3 of the 4 790's that they received had residue in the tanks, including mine. They took the tank off, pulled the fuel pump, flushed with solvent, let dry overnight, and put it all back together. I have two other buddy's that each bought 790r's at a different San Diego dealer and that dealer inspected their tanks with a bore scope camera, deemed them clean of residue and gave them their bikes. None of these bikes have had any fuel pump issues so far.
