EFI In Tank Pump Baloney
The drop in module style are almost all built using that method. Only a select few rubber fuel lines are submersible, and the ones that go in the tank, must be of that type. Regular fuel line won't last a week submersed in fuel. The submersible hose is expensive, especially in the larger diameters. I also prefer the marine-grade hose clamps.
I used a pair of Holley Hydramats fed by 10AN barbed common brass fittings to an externally mounted pump. On my set-up, they only see suction not pressure. All the pressure side is Earls stainless line and fittings.
