Yup.. pump #3 for the Sub.. this time a used external Pierburg is dying on me... ARG. While my gap was wrong (0.045) which was causing some of my misfire troubles, the real cuplrit is the fuel pump dying off.. it'll go to 60psi at WOT (15psi boost) but then quickly falls on it's face, dropping like a rock and the car starts stumbling, O2 reading leaner than 13.0:1.
Since fuel pumps apparently are consumables on my car, any reason I should avoid the $99 Walbro 255lph ones on eBay? I'm not swallowing another $242 for a new Pierburg since the life expectancy of a pump seems to be a year or two.. but at $100 I can almost tolerate the frequency... Thoughts, anyone?? The Pierburg wasn't silent, and you could hear it at idle.. if the Walbro is the same noise level, I think I could tolerate it.
