In tank electrical connection
Need to tie in my fuel pump into the harness that goes into the sending unit. How do y’all do that for in tank and protect the connections? Fuel resistant heat shrink? I’m thinking of trying to unpin the wires in the gray connector on top and connecting the fuel pump that way.

That's just wild to me. All the crap we do to keep the tank as far away from ignition sources as possible and yet leaving bare wires with voltage just sit in it is perfectly normal.

I mean it is the vapor that sparks up not so much the liquid.

There's barely any oxygen in the space above the gasoline fuel tank, it is mostly fuel vapor. You would have to blow air in with your blow gun to get enough oxygen to support combustion.
On a side note, the reason that such thin wires are in the fuel bucket is because the ampacity of the wire is greatly increased by the cooling from the fuel. When you look into wire capacity, the charts usually are for so many wires in conduit. A single wire free in the air has a higher rating than a bundle of wires in a conduit, and wires submerged in coolant are the highest.
