1939 Chrystler fuel pump rebuild kit

I want to rebuild this pump do to the cost of a new one. the only # I can find on it is FS711A it's on the inside under the diaphram. The diapham is leaking an fuel is coming out of the weep hole at the top of the pump. I can't find anyone that has a rebuild kit or at least the diapham. Any help please.

 

Andy Bernbaum catalog lists new pumps for $69.50. NAPA may be able to order one, I got one for my Dodge flathead there.

 

Thanks JC Whitney wants $101.00
