Without going back and re reading the resto process I'm not certain if this was completed previously. Since it's not an easy removal, though easier than a belly tank, I'll offer this suggestion. If it not an electric pump, then find one you can temporarily plumb in. Not to drive the engine, but rather to sample the current fuel. Take a sample and inspect the liquid for debris, rust, water, or other contaminants. How does it smell? Old? Metal tanks rust at the bottom from water in the fuel. If left to stand in a mason jar, water will quickly separate. The best way would be to pull the tank and look inside. Given the new sender and having watched his videos, he likely dealt with any tank issues. If the sample seems good but a bit old, use the electric pump to completely drain tank, refuel, and replace the filter. If the tank is really rusty, I'd oot for a poly tank, fuel leaks are particularly troublesome in boats, don't take a chance.
