255lph pump acting funny
 

I just installed a Walbro 255lph pump. Im 100% positive i did it right. My question is when I first started it up after the install I couldnt hear it at all and there was like .5 gal. of gas in the tank. Now no matter how much gas i have in there, I can hear a low pitch whirr but sometimes like when my AC is on or when Im at idle and i step on the brake, it goes away. If I rev my car i can hear it again. However, the FP guage shows constant pressure. Does this mean the pump doesnt have enough power to stay on? :confused:

my buddy has a 97gt with a 190lph fuel pump and it does the same thing, it also gets louder when the turn signal is blinking. he hasnt had any problems with the fuel pressure though, so i guess its only the noise thats going to get annoying, i think your ok with the fuel pressure though.
