If you're going to drain the gas there's a procedure for it. I drained the gas out of my RT/10 a few weeks ago because it sat for 4 years while waiting for me to put the engine back in. Gas tank is not accessible from the RT/10 trunk or anywhere without major surgery. I jumped the fuel pump relay method....
- Basically, pull out the fuel pump relay, run a bypass wire to connect the ignition switch output to the fuel pump relay output Pins#4&5.
- Purge the fuel/pressure from the intake manifold.
- Disconnect the intake manifold fuel line from the fuel supply line behind/above the transmission area. OR...you can use the schraeder valve atop of the intake manifold. I had fuel line and connectors around so it was easy for me to hook up to the fuel line.
- Connect a line to the fuel supply line (or schraeder valve) and run it to a container.
Then turn the ignition to ON (without starting). What this does is allows you to continuously run the fuel pump so that it doesn't stop after a few seconds when you turn on the ignition switch. You'll hear cavitation (air bubbles), turn it off for a moment so that you don't burn out the pump. Repeat.
I emptied almost 10 gallons and refilled with fresh gas. The procedure is easier than it sounds.
