1937 Ford Truck pressure cap conversion

Cap - 37 - 4 psi

Regular price $49.99

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!

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

Build time estimates [Feb 2025]

Brass/Black Model Ts

Our longstanding foundry (supplier) closed and all production was shifted to a neighboring foundry.  Apparently many of the closed foundry's workers were ineligible for rehire by the new foundry due to more aggressive immigration enforcement and the union has no employees to provide.  As of 2-20-25, we should receive castings in March 2025 and can resume production then. 

In the interim, we have been working with our one-off foundry to have pattern boxes made and these are trickling in in smaller batches and we will produce what we can.

Model As 5-6 weeks

Heater cores ~6 weeks

Model A and 32 Ford Street rods 6 weeks

Common street rods ~12-15 weeks

Tricky customs & complicated restorations ~16 weeks months

We appreciate your patience as we continue to recruit and train new fabricators and manage the labor shortfall our country has been experiencing.
