1. I dropped the tank this morning. Thankfully, the vehicle was facing downhill a bit and also it had only about 1/8 of a tank of fuel.
2. I removed the fuel pump from the tank and plugged it back into the harness. It did execute a prime cycle normally. I did it a few times.
I suppose It could
have been a bad connection. However the fuel gauge worked normally even when it was not pumping and it uses the same plug so I cannot really blame the connection. In addition, the connector is clean with no debris or corrosion in the plugs to make me suspect the harness.
No special tools are required. For anyone else doing this, here are the lessons learned so far.:
1. To remove the filler neck hoses from the tank, open the hose clamps all of the way so that the hose can stretch to clear the bump on the tank connector.
2. To remove the electrical connector, First slide the little red tab sideways, then press the gray tab down to pull the plug apart.
3. To remove the small evap line; the 2 clips can be gently spread apart and the line will slide off easily.
4. The larger fuel line can be removed by pressing the 2 blue clips into the hose connector with one hand while pulling the hose with the other. No force required.
The lines and wires are long enough to allow the tank to sit on the ground even with the rear left wheel 4" in the air. I did all of the unplugging after the tank was on the ground. You will want something to plug/cover the fuel outlet when you unplug it if there is more than 1/4 tank of fuel in it.
