I know many who drive their cars have issues with hard starts when the engine is at operating temperature.
I was working with another member here and suggested not only using the 3/8" Canton Phenolic Carburetor Spacers but insulating the fuel line from the apron to the pump but about a foot and a half on pump to carburetor and the phenolic fuel pump spacer. The changes lowered the fuel temperature almost 10 degrees. For those who have never seen the pump spacer I posted it below.
