Frequently Asked Questions

No, part number 135-7 is designed specifically for 50cc accelerator pump assemblies. If your carburettor utilizes a 30cc pump housing, you will require a 30cc diaphragm (such as Holley PN 135-5).

No, PN 135-7 includes the 50cc black rubber diaphragm only. Re-use your existing pump housing cover, return spring, and mounting fasteners, or purchase them separately if required.

Standard black rubber diaphragms are ideal for pump petrol and race fuels. For pure methanol or high-concentration E85 applications, GFLT or alcohol-specific diaphragms are recommended for long-term material compatibility.
