Got a 20 gal load of what seems to be watered down fuel. Much missing and rough running with a final stop of engine. Sit for a short time and started up and got it home. Replaced both filters and both were old and dirty. Also replace oil and filter plus air filter. Many tries to start failed until battery dead, after charging tried to cycle pump on and off to purge water from HFCM much water seems to come out but would never run. Water light still on dash. Took inlet line to HFCM off and installed hose to a clean 5 gallons of fuel. Still little pressue out of the HFCM and no filling of the secondary filter. Now it seems to have no fuel pressure to secondary filter. At over $300 I want to make sure it is a bad pump, what pressure should I get from the frame mounted pump? Thanks for any help Barry Perque
