I have a 2000 Tahoe 4x4 4 door. Fuel pump is out. What is the best way to drain a half fuel tank? I know to pull the relay, and undo the fuel filter. Which prong of the relay rcptl do I jump to power the pump?
Unfortunately the best, and safest way is to siphon the fuel out with an old garden hose, suck and blow never swallow. Some auto parts stores carry Gas siphons, either a small squeezable bulb to build vacuum and start a siphon or a plastic pump that can be run by a drill. I have a squeeze bulb I use, works great, had a plastic pump and it worked maybe 2 times.
OK thanks. I removed the relay and jumped across the connector pins 30-87. With the fuel filter removed and a hose in place of the filter leading into a gas can I was able to pump the fuel out of the tank. Well most of the fuel till the pump stopped working again.
