Straight 8 Single Action Fuel Pump Possibility?

[Aaron65]

Hey everyone,

My '53 Special (263) has always leaked from its double-action fuel pump vacuum port.  I've owned the car for 16 years, and I've either rebuilt the fuel pump myself or bought a remanufactured one probably 4 times.  The pump stays dry for 6 months to a year or so, then it starts to weep, then it starts to leak.

Is there a single-action alternative from a different year that will work on a 263?  I almost never use the wipers anyway.  I'm sick of the oil leak!  

Thanks!
