Not sure if i shoul deven be concirned or not but I got a new fuel pump from one of those Ebay companies. Said it was similar to the Walbro pump with a 225 lph flow rating and was a direct replacement for the stocker (inside the bucket deal). Got into the replacement and pulled the stocker. When I compaired the two pumps side by side this new one has a threaded hole in the top that the stocker does not. See....

Does anyone know what this hole is and what I'm supose to do with it (if anything)? I e-mailed the company this afternoon but yet to hear from them... I hate things like this becuase it makes me feel like an idiot.
