The Brassworks will pressurize your system with an optional pressure cap neck located out of site beneath the hood.  For every pound of pressure your raise the boiling point of water by 3 degrees. With our recommended 4psi cap your boiling point climbs to 224 degrees and with 50/50 mix closer to 235 degrees. Higher pressure caps are not recommended due to other system components constraints.

With a blocked off filler neck on top and an underhood pressure cap (invisible to the public) your Model A will look authentic outside and keep the engine cool inside. 

An added sense of security when in a slow moving parade, creeping up a long uphill grade, mountains or desert travel, and ideal for the active touring car.  A great addition for cars with overhead valve conversions or higher compression heads. 

Price: $610 for flat tube pressurized with 10FPI & $4.99 for 4 psi caps

The Brassworks also sells overflow tanks for Model As and other classics that are designed to blend into the engine compartment and capture any fluid from the overflow tank
