Knock at 12lbs??

[fastezz]

OK my car is running stock 11-12lbs of boost and I am getting almost 30 counts of knock, my theory is that since my fuel pump has 159k miles on it its just not working as effeciant as it did the first day it was started, I have a walbro 255 fuel pump waiting to be put in, but I just have no gotten around to dropping my tank to put it in, I am also going to be putting in a 2g maf and 550`s at the same time, I also have a SAFC and have tried richening it up, but when I do it doesnt do anything except for cause fuel cut, so I am almost dead on that its the fuel pump, let me know what you guys think.

Do you have a log?

Is the knock at part throttle or WOT or both?

Get a log with rpm, o2, timing, and knock.

I am going to rewire my fuel pump today, and then some time next week I will be putting on my 2g maf, walbro 255lph fp, and my 550 injectors, but i will rewire it then log it later on today then load it up here.
