3800sc swap with walbro 255 pump very very loud whine. any ideas why ?
Yes, It's a Walbro. That's one of the things that made me appreciate removing the one I had the most, the noise. I believe they were designed with the intent to be high performance pumps only with no consideration for anything else and like gas mileage, practicality in normal daily driven settings, is of no importance.
Unfortunately many of us have fallen victim to the high performance rating and not looked any further to seek out pros and cons. In addition to the noise, they don't like and can not withstand the kind of heat that stock pumps can for those who run their tanks down to a 1/4 or less.
I replaced mine with a Deatschwerks. I'm not plugging for them but I liked what I read and the fact that I can hardly hear the pump running in the tank which is a good thing.http://www.deatschwerks.com...pump-reviews-are-out
