You cannot, because of the screen blocking the fuel tank filler pipe, siphon the fuel via the filler pipe. However, there is no screen on the filler vent pipe. Remove the vent line hose at the tank, check the inside diameter of the vent pipe. Go to a building supply store buy four feet of so of clear plastic tubing, 3/8 inch outside diameter should do it, but check first. Insert plastic tube via the vent pipe into the tank and start the siphon. Worked very well for me and I removed nearly 17 gallons in less than 45 minutes.

27.5 USG the answer found here of 27.5 gallons is incorrect. the actual capacity is 18.2 gallons. the previous body style sedan and coupe may have had a larger tank but when they switched to front drive transverse engine it had an 18 gall tank.
