EFI tank with Carbureted engine plumbing questions

Cheap knockoff. Like 20 bucks or so. The oriface had to be opened significantly to lower the pressure enough. However, it works perfectly and keeps fuel cool and no vapor lock.
I also run 3/8 feed and 5/16 return.
Thanks! I was just looking up the regulators on eBay tonight and watching a bunch of review videos on them. I noticed today that my mechanical pump has started leaking, and I’ve been wanting to put the magnum serpentine setup back on the engine anyway, so I think I’ll get one of those regulators and go ahead and get the swap done.
