[VAC] parts for rebuilding water pump

[jon fitz <fitzjo1@xxxxxxxxx>]

Does anyone know where I can get parts to rebuild my
water pump?  It's a peters and russell model 6800.  I
need two small disc shaped check valves and the gasket
for the pressure chambers.  I wouldn't mind a new
diaphram, either, although this is OK for now.  There
are no parts listed in my RV "master catalog."

Many thanks.
