This is the one I am talking about. They don't even offer a 3lb spring. I can't find much information on how a bypass is different than a BOV. I know the difference in their intended purpose but as far as the mechanical construction of them, I am not sure. Besides the fact that it is a directed dump vs. 360* dump what is the difference? Can you use a BOV if you wanted?

I am dumping to atmosphere pre-intercooler. No filter since it will be blowing any debris away and can not ingest anything.
Good call on putting in a safety setup for that pump. I still have the oil pan spacer and a fitting for you.
