New Walbro fuel pump question
I just replaced my Walbro 255lph inline fuel pump and noticed that right out of the box it whines loudly and makes a screeching sound when its primed on occasion. Is there any chance that there is some kind of break-in period that the pump needs to work at 100% or am I looking at a defective part?
Thanks!
Thanks!

It looks like the pump will start whining loudly after its been on for ~15 minutes and at that time the PSI in my rails will have dropped from about 23psi down to 20 or 21psi. On occasion the pump makes a slight screech at startup which ust sounds aweful... Bad pump or whineboro?
