Hey there gearheads! If you're working on a dune buggy or any vehicle with a Weber or EMPI carburetor, this accelerator pump diaphragm is exactly what you need. This little guy fits progressive 32/36 carburetors and those EMPI 38E EPC models too. It's a direct replacement part that'll get your carburetor running smooth again. When your accelerator pump isn't working right, you know it - that hesitation when you step on the gas, poor acceleration, just general sluggish performance. This diaphragm fixes all that.
