You two are 100% spot on. Drilling below the fuel level in the tank is a hack job, no other way to put it. It’s a safety issue as well, not to mention you’re tapping a tank that was never structurally designed to hold an NPT tapped opening in the sidewall. NPT uses tapered threads to seal and there is NO WAY you get enough thread-to-tank engagement in a thin plastic tank. And if you have any kind of accident that connection will just snap out of the tank below the fuel line, dumping 15 gallons of fuel into an accident scene. There are obvious reasons why OEM does NOT do that. Use a low side system that goes on top of the tank using a proper hat at the top with the fuel pumps submerged like multiple manufacturers offer. The fuel helps keep the pumps cool and lasting longer to boot.
