walbro grinding
 

searched around a bit found 2 on here with no answer and links to the same two on google, anyway my walbro is making a growling/grinding noise. At half tank or just under it makes the most noise while braking, around 1/4 tank (which it doesn't see often) its a constant growl even during priming.

Return it for a new one. I assume you are familiar with the normal priming noise that is louder than a stock pump but if it sounds like grinding then something's wrong. Even quality components have bad units that get out. If you're sure it's installed correctly then give them a call.

its an in tank, i pulled it yesterday took a look at it nothing seems physically wrong with it i changed the sock and it still didnt go away. Yeah i know the normal priming noise, and it sounds normal with a full tank just at around half tank it starts acting up. No problem with fuel delivery tho, just makes me nervous ill see what they have to say tho.

did you add power to it to listen to the noise it make when you first gort it?

Is it mounted rigid so as not to move while cornering or braking. Did you forget to put the sleeve of rubber on the pump to dampen the vibrations. And then when cornering or braking or when there is not enough fuel completely submerge it fuel will not act as dampener for the pump.
Or depending how the pump is mount you have the pump touching a tank baffel or basket.

Both my walbro's are loud as hell, you didn't expect it to be quiet like a stocker did you?

not running fuel through the pump on the bench will obviously make it loud as hell.
