Cooler weather is the answer. This has been a problem since the fuel pump was invented. I have not heard of a sound solution. Sure has been hot here in the midwest. I am open to ideas and thoughts. Dan
You can buy heat shields that go between the carb and intake to insulate the carb. They're just layers of aluminum plates and gaskets. If you have an inline fuel filter between the pump and carb it sometimes helps to move the filter to just before the pump. That way there is no air space and the fuel line can stay pressurized and is less likely to boil.
I do woodworking for my meager living so this was'nt a real stretch for me. I scroll-sawed out a wooden carb spacer from some Baltic Birtch plywood I had left over. Made it a 1/2" thick 4 hole spacer. Wood is an excellent insulator. You can buy the wooden ones in Jegs also. Works fine for me. clint
Furniture makers ..do it with the hardest wood. Good to know another woodworker is on here. Make my living making mesquite furniture out here in AZ. Could be a nice touch on the car, almost no expansion to worry about so it should work about as well as ply.
helps a lot to insulate the fuel lines, like you might for the track. cover the lines under the car with the smallest diameter pipe insulation wherever possible from home depot. crumpled aluminum foil with wire ties works well under the hood. its not just engine heat, but also comes from the 120+ deg roadway you drive on & absorb heat into the metal fuel line from. under hood the metal lines also absorb heat. yes a carb insulator definitely helps, too. cold air inlet also helps.
Good info Darn good info. Thanks, I will try the wooden spacer and the line insolation. I will let you all know how it works.. thanks
