Model B Fuel Pump HYGRADE fp-159

[Ranger351]

Folks,
Having trouble finding parts to rebuild/replacement fuel pump for my 1932 Model B 4 cylinder...The pump that came on this is a HYGRADE products FP-159 (inside of top half has F-P-157-D). I need to replace the diaphragm, 3.25" diameter, 6 holes, staked to a 1-7/8" long T shaped pull rod...any ideas? I have found this airtex pump for early 40's dodge wc, but the pressure is 6.5-8psi, the mount looks right though, and I like the glass bowl idea...

The hygrade appears to be a clone of the standard 32 model b AC type...

Thanks for any help you can offer,
