Review on Motion Pro 08-0013 Brass Carburetor Adapter: High-Quality 5mm x 0.8mm Adapter for Enhanced Performance by Mike Snedeker

One of my previous adapters broke off in my carburetor, these are much thicker and heavier, I never see them break in carburetors. I wish they were a bit longer but actually they are exactly what they should be. Any shorter and there will be a problem. One of them seems to have some sort of material, like a sponge, wire type, I wouldn't be surprised if it just buffered the air before it hits the vacuum gauges. I have used them several times, they work as expected, I am satisfied.
