Fuel Boil/Carb to Manifold Phenolic Spacer

[G.M.]

Bob Shewman in my opinion makes the best carb. insulators. His are thicker and drilled for additional cooling. They come with the longer studs. [email protected]

And his flex fuel hose with the check valve is a great addition as well.

Scott thanks for the pictures. As we can see the spacer is 1/2" thick and the additional vent holes are visible. G.M.

I also want to point out from your fuel pump picture the larger clearance between the fuel pump and intake manifold with the cast iron manifold.
With an aluminum intake the pump almost touches the manifold making fuel pump vapor lock more aggressive. This problem is starting up again with the warmer weather according to recent posts. I might also suggest higher fuel pump pressures reduce the VL problem. G.M.
