2.8 GALLON FUEL TANK  

IMPORTANT: THE MAXIMUM TORQUE SPECIFICATIONS FOR THE FUEL PUMP BOLTS IS 5 FT. LBS. OF TORQUE WHEN INSTALLING THE FUEL PUMP OR YOU MAY SPIN THE BRASS INSERTS AND VOID THE WARRANTY OF THIS TANK. IT IS RECOMMENDED THAT YOU USE A QUAILIFIED MECHANIC WHEN INSTALLING THIS PRODUCT. 
1.  Begin by removing the original tank from the bike following the original owner’s manual or manufacture's service manual.
2. Make sure to completely drain the tank before removing the original fuel pump. Be sure to work in a well-ventilated area and avoid any open flame or smoking. Once drained remove the original pump and save the O-rings as they will be reused. The seat mount and rear hold down screw found on top of the tank need to be transferred from the old tank to the new tank. 
3.  Make sure your new tank is thoroughly clean on the inside by using compressed air to blow out plastic debris left behind from the manufacturing process. Now proceed to install the fuel pump according to the owner/service manual. Add a small amount of fuel to check for leaks and if any are found remedy them before proceeding any farther. Once tank has been checked for leaks installation may begin. 
4. Install the tank onto the bike using the owner/service manual instructions. Only differences depends on if you are using a steering stabilizer that uses the front mount bolt or not. If not then 2 washers need to be added to make up the difference between the frame and rubber grommet. Do not tighten down the bolt at this time as it will make shroud installation a little easier.
5.  Test fit shrouds and check for interference on the rear most part of the tank. It is common to have to trim the shroud in this area to clear the tank. The trimmed spot will be hidden by the seat. Once clearance is obtained you may install the shroud bolts but do not tighten at this time. Now you may attach the rear rubber hold down, and tighten down the front mount bolt and then the shroud bolts. 
6. Add approximately 1 gallon of fuel and double check for leaks. If none are found install the seat and double check all bolts.
7. Ride and enjoy your new Clarke tank!
