This is using a factory flex fuel bucket, one thing to note is the factory FF fuel pump wires and connector will handle the amps of the 4303 but I wouldn’t recommend running it off of a trucks factory wiring that wasn’t originally FF.

 

 

I ran a -8 feed and used the factory -6 as the return, I have the holley high ram intake and rails though which are -8. I used a Magnafuel boost referenced regulator and as for the filters the pre filter you see in the bucket is a fuel lab 100 micron stainless and the post filter is a Magnafuel 25 micron I believe.
