My old walboro fuel pump was making a slight whining sound, and since I am putting twin turbos on next week, I upgraded to a 255lph walboro fuel pump. The whine went away for 3 days, and now it is back and louder than ever. Any ideas?
ya even my 155lph walboro is loud. i can easily hear it over my exhaust and engine at idle. to me, its a good thing, at least i know its working. cuz the last time i couldn't hear my fuel pump, it meant it was dying.
