1937-1938 Ford Truck pressure cap conversion

Have you ever wanted to add pressure to your 1937 or 1938 Ford Truck? The 1937 and 1938 trucks were designed as a non pressure system and the cap fit inside a decorative chrome piece.  Many people want to add mild pressure so we created an insert that joins to a 4 or 7psi cap for early flatheads or 10, 13 or 16psi for more modern engines.    Seal the over flow tube, add a pressure filler cap and voila, you have pressure!

Made  to order.  Allow us a few days to construct.
