Hello again. Steps so far.disconnected fuel line to carb and as some fuel came out of pipe (raised the end of pipe an plugged it to stop fuel gravity flowing) I guess that the fuel that came out of the fuel line was only the residue.Pump reconditioned and refitted.Fuel line reconnected and manually primed but nothing came through.Turned motor a few times but still nothing. disconnected fuel line and tried blowing through back to tank,no result.Tomorrow I will try some more back pressure to tank. If still not clear I will loosen the pipe connection to tank and see if fuel dribbles out, if it dribbles out then I will check the fuel line. if no dribble I will siphon empty the tank and disconnect the pipe and try clearing any blockage in tank. I have a nasty feeling that this going to be an expensive job.
