Ok folks here goes old Arch off again on another quest...
4. The winner is one from Auto Zone part # 74612...

Thanks Arch,
I recently acquired a '73 26'. I had a miserably hot, 225 mile drive
home.
Until I began reading here, little did I realize that the hot engine
coolant might be passing thru the heater core. I'll take advantage of
Your experience rather than inventing my own wheel regarding this valve.
Please let me know if it fails to serve as well as You anticipate.

I also had not recognized that Engine failure would result in diminished
braking capacity (duhh). About 50 miles into the trip the engine died
just the same as if I had turned the switch off as I was climbing a long
hill.
In attempt to reach a better place to pull off, I let her coast as far
as inertia continued to overpower gravity & drag so I didn't experience
the loss of brake power. Found the Engine problem to be the points, so I
thought that the elimination of the points would be my first upgrade.
That now though, appears to be much less important than enhancing my
braking system.

Having followed the recent thread on the back-up vaccum pump, I plan to
add the pump with automatic control(vaccum switch) NOT connected thru
the ignition switch but an auxillary equipment circuit with a manual
switch.

My question is; Is there any advantage to be gained by adding a larger
vaccum reservoir? Say something like a large refrigerant bottle in lieu
of the oem cannister?

Thanks for everyones efforts & opinions.

Have Fun, Tim Timothy
 
re vacuum pump. I didn't think I needed a second or larger reservoir is
needed. I installed the vacuum pump after my engine died once on a steep
hil. If I had not put the unit in park, it would have been over. I like
the vacuum pump and think it will work fine.
