Nice work and thank you very much for going through all the details of this install . Have you seen anyone run this filter instead of the fuel regulator set up - Part # 162-591 HOLLEY EFI GM STYLE FILTER/ REGULATOR -6AN Filter / Regulator Assembly, return style preset at 58 PSI, -6 AN connections. I bought a used system like what you are showing and it was plumbed only with this filter .
