Skip to contentCap - 37 - 4 psi
Have you ever wanted to add pressure to your 1937 Ford Truck? The 1937 was 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!
