I'd check the gas cap as mentioned above and look for any possible air leaks anywhere in the fuel system between the pump(s) and the tank. Anything that can add excess heat to the fuel system, including auxiliary pumps and filters placed too close to a heat source, can cause issues that often show up after a few miles of driving, especially in warmer weather. Filters on the suction side of the fuel system are notorious for causing problems, especially in warm weather. Any missing heat shields and insulation related to the fuel system can cause issues. It's very common to have fuel delivery issues in warmer weather when using the gasoline sold today. The best choice is aviation fuel, if available, and second choice would be ethanol-free gasoline. "Tier One" gasoline may give better overall results than discount fuels. Operating at higher elevations in warm weather can aggravate problems with vapor lock or fuel percolation.

I have a '37 120 convertible for 2 or 4 which I very much enjoy ....and I'd love to add a V-12 in the same body style.
