Years ago I experienced vapor lock of sorts. Carb floats regulate liquid not vapor (boiling gasoline). Gasoline vapors spilling all over the from the float bowl vents. Most fuel pumps move fluid not vapor and when hot gasoline has the presure reduced by pumps pulling rather that pushing, gasoline can seperate from liquid into vapor. I went to a higher presure and volume fuel pumps (maybe too much higher). I mounted the electric fuel pumps low just in front of the fuel tank sump. But the thing I used at the time was a BG diaphram adjustable fuel log . I mounted it on the right side close to the carb inlets with short connectors to the dual carb single inlets. Adjustable outlet spacing, adjustalble presure (6 psi). I ran a fuel hose from the fire wall forward and turned it to enter the fuel log at the front. Fuel circulates rearward down the fuel log. The return type diaphram adjustable fuel presure regulator in this configuration, is located at the rear of the fuel log. It holds back 6 psi and returns over supply fuel to tank. Always fresh cooler fuel from tank available (circulating) just about a couple of inches from carb inlets. All wrapped in reflective heat barrier material. BG seems to have gone under but there are lots of fuel product manufacturers still out there. I have never had any problems with this BG fuel log. I do not know what I'll do if and when it does.
