Fp regulator mods

Greg,

I didn't pay this much attention at first, because it seemed 
beyond my capabilities.  Mostly because manufacturing a 
diaphram with the spring seat, etc would be impossible for 
me.  But the more I think about it, the more I like the idea.

Maybe I can find an existing larger diaphram from a larger 
regulator, or and EGR valve, or a A/C vent mechanism, or 
cruise control, etc.  (Any other ideas?)  I would need one with 
a diameter of ~2" to achieve the desired rising rate.

Connecting the new top to the old bottom will be tricky part.

After my post last night about adding a larger diameter pipe 
to the outlet side of the reg., it later occured to me that it may 
not work either since, once the diaphram lifts to relieve pressure, 
the entire underside of the diaphram will be exposed to the fuel 
pressure.

Anyone have a cheap milling lathe for sale? 8-)

Thanks,
-Mike
