How do you replace the sending unit for the gas gauge in a 1998 XCV70?

I own a 1998 V70 AWD which is similar to the XC70. The XC70 is also all wheel drive requiring the rear cross member and rear differential be lowered in order to lower the gas tank. The fuel level sensor is mounted in the front of the gas tank and cannot be removed until the gas tank is lowered. The fuel level sensor is on the left side and the fuel pump assembly is on the right. This is a job best left to professionals as a vehicle lift and special equipment is required such as a lifting table and post jack to lower the rear end and the gas tank. I am a Volvo Technician and in the process of replacing a fuel pump in a 1999 XC70.
