They may be plugged to the point that they'll look like they are being sucked in by pumps. In that case I would replace the pumps since they probably been overheating trying to get fuel out. I had problem with my fuel pump filter causing the secondaries to shut down due to lean O2.

Fuel pumps test out OK. I replaced the FP Regulator during the injector swap. My FP is normal now.
