Bob,

What do you do with the mechanical pump.  Is it removed and the
hole covered over?  Or does the electric pump "pump" through the
old mechanical pump.   If so can't you end up filling the
crankcase with fuel if the rubber diaphragm get a hole or splits.

I wonder if the old pump can be "fixed" to just be a pass-through
fitting and not allow a leak.

Fred-
A while back my fuel pump pivot pin fell out, and the lever
worked its way
further in where it jammed the cam and snapped it! As I remember
it, only
the fuel pump lobe and the #4 exhaust valve were affected.  The
car would
run ( although terribly) 'cause I had a backup electric pump.
You will like
the electric pump concept.  It allows you to fill the fuel bowls
prior to
cranking, much faster than waiting for the mech pump to fill the
bowls...

Well, I've finally discovered why my car stopped running when I
got back
from Illinois, the camshaft is no longer turning the arm on the
fuel pump to
feed the gas to the carbs, this a.m. I took the F.P. apart,
removed the
diaphram and bolted the pump to the block, no movement of the
F.P. arm at
all, none. I called Ken Galanders on Friday to ask if he had ever
heard of
this happening, and he said no, not on these cars, the high point
on the cam
lobe is still there, I do feel a little indentation on the rear
of the cam
where the arm would normally ride. No more concours judging this
year, a
electric pump with regulator goes on today, this cam has less
than 40K miles
on it, they should be good on a fuel pump hook-up for life, never
wear out,
sure don't understand this. Anybody on the list ever had such a
happening ??
