Dave,

The reservoir tanks are from GRP, they will fit most pumps that accept the 4 screw mount to the valvebody. Even if the old tanks use the bottom screw most will still have the holes for the newer style mounting..
The Cig tanks were not the normal they sell, the filler bung needs to be on the opposite side from their std tank. They still had some in stock.. If you need any more pics let me know..
These do not leak!!

You will need to call them to order the tanks only, no brackets, unless you want to rewire and run new lines...
