[QUOTE="Goose17, post: 15404924, member: 137255"] Finally got all of the old gas out of the car tonight. I did 3 different attempts at getting out the gas. After reading-up on the subject on the Internet, I found quite a bit of general info on getting out the gas. There was nothing specific to the Cobra R. The R has a 21 gallon rubber bladder inside a metal tank collectively call a "fuel cell." Here is what I did: First attack was using a small vinyl tube to navigate through the anti-siphon filler neck. I connected this to a squeeze primer ball and put the other end in a gas can. I've used this to get gas out of my boat and it works well when used with large tubing. Once you get it flowing, gravity will do the rest over time. Since I don't have a lift (yet) and the fact that the fuel cell is so low, there was no gravity-feeding. I had to continually pump. This process took a long time, but I got almost 5 gallons out this way. Exhibit "A" [ATTACH=full]694051[/ATTACH] After that well went dry and the gas gauge still indicated quite a bit of gas onboard (incidentally, the 00R's were known for inaccurate gas gauges), I switched to a vent tube hole. There is a tube that appears to be a vent tube that enters the cell above the filler tube, I removed this and inserted a larger vinyl tube and once again pumped more gas. This got me another gallon or so. Exhibit "B" [ATTACH=full]694052[/ATTACH] Let it be known that once I get a lift, the bottom-side of this car will be as spotless as the topside! After "well-B" stopped producing, I switched strategies once again. I read and watched videos about jumping the fuel pump relay and pumping out the gas. Few problems with this... 1. With limited manuals on this car (no shop manual or detailed owner's manual), I wasn't exactly sure which relay was for the fuel pump. 2. Not sure I wanted to experiment jumping the relay with no solid info on which connectors to jump. 3. You run the risk of burning up the pump if it's running and no fuel is going through it for cooling/lubrication. I read and watched videos about tapping into the fuel rail through the Schrader valve (think bike tire inflation valve). When you cycle the key to "on," the fuel pump runs for a second or two and pressurized the rail. With tapping into the rail, you can pump gas into a tank. This is exactly what I did. It would have been easier to jump the relay and allow the pump to continuously run, but I didn't have that luxury. I also considered trying to start the car (not sure it would run) to allow the pump to continually pump the gas out, but decided against it.
