Accelerator pump diaphragm

Looks like my front pump diaphragm has developed a little leak depositing fuel onto the intake manifold. Its a 950 Proform Carb. I think they are basically Holleys and the Diaphragms are sized in cc's. Anyone give me a steer as to which one I should be getting to replace the leaky one?

Thanks all.

Yep, look at the pump body thickness, the 30cc is very slim the 50cc is about 1/4" thick.
