1998 XC70 How do I drain fuel tank ?

[pedal2metal]

Make sure it's not your cam & or crank sensor first; I made the (expensive) mistake last year when I thought for sure it was the fuel pump that went out... but here it was the cam sensor! I almost cried after all that work & then the car still wouldnt start! What a mess, but the car now has a new factory fuel pump in it. So, I guess it'll last another 175k. lol
