Surge Tank Removal - modification When I installed A/C on my R2 I had to eliminate the surge tank and install an outlet and overflow reservoir tank. I used the thermostat neck(water outlet) from a Stude V8 part number 1550844. To connect the rad to the thermostat neck I used a lower rad hose from a 1994 Thunderbird 3.8 non supercharged engine. Cut 2 1/2 " from the small end and it fits perfectly. You may want to remove the inner spring as it is not needed . Peter Sant, July 2000
