I ordered an EFi tank with the pump already installed from Holley, all from FASTMAN.I emailed Richard about the 350 pump, waiting for a reply. He sent me this regulator https://www.holley.com/products/fue...lters/filters/efi_filters/parts/162-554. I’m a newb when it comes to EFi but if this 350 pump will work it will save me a lot of work. If there’s a reason he didn’t want me to use it that’s fine also.
