What fuel pump? That's the EXUP servo you can hear.

Check the fuel tap isn't blocked and the main fuel hose to the carb isn't perished or kinked. Try emptying the tank and making sure there's no loose bits in it.

The fuel pump is the ticking noise when you first turn the ignition on - the exup is a weep weep sound.

Take out the fuel tap and clean the filter on top of it. Renew the fuel filter between the tank and fuel pump. Check the float bowl gaskets are ok - they can go hard and loose their seal. Tap the floats lightly and make sure they bounce on the valves then take the floats off and visual check the valves for wear.

I think it's the fuel filter.
