Wait, just checked out the fuel pump install post, you have a filter before the pump! You can't do that. At least, not with a small one like that. EFI pumps are NOT designed to pull vacuum, and that means be fed by a fine filter or long run or uphill run. They are designed to push pressure, take a little soft junk, and force it INTO a filter. On my ute I have a massive marine filter with housing that I suck fuel through with a carter black vane pump and had trouble with even that sucking the hose down due to the restriction of this huge thing. That feeds my surge tank and the 044 pulls and feeds the rail from the surge tank with no up stream filter (though there should be one). You need to migrate that filter into the supply line post pump, not pre pump in between pump and tank. Having said all that, your reg still sounds to blame.
On the tank side you need something low restriction like a gauze or sock, only. Or something massive like the marine one I have + something that CAN draw a vacuum.
