Question About New Fuel System

[LuckyHenriksen]

So I am redoing the fuel system to accommodate the new motor and FCG tank, and have some questions. I will be using Aeroquip start-lite hose, or something similar. When I make the connections to the fuel pump, and filter, does each piece have to be made specifically? I can't cut and attach my own hose ends can I? And what should I run as far a filters? I plan on a 40 micron after the pump, I hear some guys say that will be fine, and others suggest a filter before the pump too. And last question, when I reach the engine bay, I plan on having a Billet fuel log to feed the double pumper, should I mount it facing forwards, and have the fuel line go all the way up to the front of the motor and up to the top? Or can I run it up the back of the motor somehow. I just don't know if it would interfere with the headers, or other sharp objects. Thanks for your help.
