Fuel pressure regulator

["John Hofstetter" <hofs@domain.elided>]

Dennis,
I was slow getting to my new digests and when I read your post, I
expected to find multiple answers to your questions in the next couple
of digests, but with this being the weekend, I guess everyone is
occupied elsewhere.
Yes, they sell in line fuel pressure reducers, both pre-set and
adjustable. 
I personally doubt that the leak from the carb is caused by that old
fuel pump having very high pressure, but it is possible.  I doubt that
if you really have excessive pressure that it damaged the carb.  The
only parts of the carb that are involved in stopping the flow of
gasoline into the bowl(s) is the needle valve and seat, and these are
replaceable, although they might be the cause of  your problem with
overflowing, that problem wasn't caused by excessive pressure. 

There is no big problem with leaving your old fuel pump hanging on the
block as long as you don't pump gasoline through it with the electric
pump, and the cover plate just kind of classes things up. 
I don't know the answer to your question about the listings on pumps,
although what you surmised certainly makes sense.

Subject: Fuel pressure reducer

Is a reducer valve for the pressure of an electric fuel pump an easily
purchaseable item?  Local speed shop likely to have?  My fuel pump
went out
and I remembered that there was an old electric fuel pump already
mounted to
the frame from when my grandpa had his very scary auxiliary fuel tanks
mounted
to the stepsides.  I had considered painting targets on the sides but
just
removed them, and left the pump for just such an occasion.  Well I
hooked the
pump up and have used it to move the truck on street cleaning days a
couple of
times, but suspect the pressure is too high (something about the gas
covering
the sides of the carb makes me think this).  Is it likely that I've
wrecked
anything in the carb, it was only on for a few minutes at a time, and
ran
fine.
Also, I am getting dual listings for a replacement mechanical pump on
the '63
304, concentric or in-line filter.  I removed the pump and recall
seeing
nothing which makes the answer to this question obvious, except the
obvious,
that there is an in-line filter after the pump.  Is that it?  I will
be
checking my manual soon, but I toss it out there.
Also also, someone mentioned recently to remove the mechanical pump
and get a
block-off plate.  Why not just let the dead pump hang there, other
than a
desire for the neat and tidy?
