6 AWG
You can pull 10 #3 gauge wires in a 2 1/2" conduit.
The NEC allows 26.
If the wires are of identical materials, the 26 guage wire has more (higher) resistance.
The minimum size you can use is 3/4 conduit. The code allows for a maximum of 4 each # 6 gauge wires in a 3/4 inch pipe. You'll likely be running 3 ea # 6s, two hots and the neutral and a #10 ground wire.
There should be no reason to install two ground wires in the same conduit. Code requires that only a single path should be required if it is to carry a fault current. This ground wire should be single and continuous from the device back to the distribution panel. It is the fault current that is carried on the ground wire that trips the breaker or fault protection device. Don't confuse grounding wires with bonding wires.
Connecting different gauge wires are just like connecting wires of the same gauge. Connect the wires just as you normally would, and then once the you attach the wire nut, give the thinner wire a slight tug to make sure the wire is securely fastened. Usually when attaching fixtures, they are generally stranded wires. Be sure to twist the strands together before twisting them onto the solid wire. Then attach the nut onto them and tighten it securely. Connecting different gauge wires are just like connecting wires of the same gauge.

Yes Yellow and Red are for minimum 2 wires and maximum four wires. Yellow are for 2 14 gauge wires, or 4 18 gauge Large Red are for 2 12 gauge or 4 14 gauge
This is to avoid energy losses in the connecting wires.
Connecting wires in electrical terms is called an electrical splice. All electrical splices have to be made in a junction box.
It could be your fuel gauge or your sending unit or the wires connecting them . If you have dual tanks it could be the switch that changes tanks. The most likely culprit is the sending unit in the tank.

Potential difference and the conductor. A cell and a bulb. Some connecting wires. The bulb can be made glow by connecting the wires with the cell.

Wires are built to a standard (a 'gauge'). Thicker wires can withstand more current.
-- Any energy dissipated by the conencting wires is lost from the circuit, and unavailable to do the job for which the circuit is intended. The less resistance the connecting wires have, the less energy they'll dissipate. So the connecting wires need to have as little resistance as possible. -- Copper is easy to work, easy to form wires from, and is the second-best electrical conductor known, after silver. Copper is used instead of silver because it costs less. -- The thicker any wire is, the less resistance it has.
