1.7gal Reservoir to suit the Chevy SS and Pontiac G8
The reservoir goes in the outside air box compartment, it cannot be seen in this location as it is covered up by the black plastic factory shrouding.
We have raced with this size reservoir on our own car for many years with great results. Water ports IN and OUT are both -12AN male threads.
Customer supplied installed photo (note customer decided to paint the tank – this is not needed as it cannot be seen, also at this stage we used barb fittings, which are now AN-12 threaded fittings)
