I am working on getting my 2005 Toyota Corolla XRS moving again after sitting for 1 year or so. I am able to crank it but not start it after just replacing the battery.

My question is there is a better way to get the gas out of the gas tank without needing to remove the tank itself?

One thing I need to do is to empty out the gas tank of the old fuel. I am stumped on how to effectively empty out the tank, as I have bought various tools to siphon the gas. I went to Autozone and bought a "Performance Tool Siphon Hose" and that only got out so much gas. Then I went back and bought the "Performance Tool Transfer Pump" and that was better, but eventually I couldn't get more gas out of my tank for whatever reason being that I pushed those clear PVC pipes into the gas tank as far as I could but still was only about to get about a gallon out when the car says it has 1/2 a tanks worth of gas.

As I am working on getting this car up and running, I already started to check the fuel pump under the back seats and I know the fuel pump is good since when I removed the fuel line some gas leaked out, which is a good sign. But I need to wait to get the tool to remove the fuel pump before I can go further. I assume that would be another way to do it by just lifting the pump out and running the siphon tools through there. A local mechanic that my family knows mentioned that there is a drain plug somewhere under the car where the tank is, but I couldn't find one, nor have I found any info online saying that there is one.
