Before we get into the tips on how to quiet things down, lets talk about some common reasons why ANY brand fuel pump may be loud.
- Reverberation: Mounting a pump to sheet metal which might only have a few spot welds is much different than to a very solid frame. On the same note if the sheet metal goes into an open cavity it can create a sound box of sorts.
- Sound deadening: An all out race car stripped of all sound deadening material might be different than a factory car.
- Is it being loud a new thing? Sometimes when a pump starts working harder due to clogged filters (or becoming more clogged gradually) as well as a small or damaged power wire may elevate noise. Be careful and knowing of this.
