Noisy fuel pump.

[AhPunk]

Anyone got any idea what could be the reason for a brand new bosch fuel pump is rather noisy?

I put in a new one and it is louder than the old dead one i would guess stronger non 15 yr old motor

The Bosch fuel pumps inherently have a louder electrical motor than stock. Its not a design flaw, just different engineering.

thanks for the reply, i do understand tat the pump is more powerful, can support up to 400hp machine, the problem is, the noise is not constant, like unconstant kinda "click" sound.

I checked, and notice tat the fuel pump cover is somehow bent, not to the original patent, is this causing the problem?

:werd: if so why the noise is not constant?

The click sound is usually the pump kicking on. wierd
