At the behest of my wife, who has some concern about me bombing
around in an LBC, mixing it up with SUVs on the freeway, I decided to
put a little money into safety stuff on my '64 B.
The most obvious one was to install a fuel pump rollover switch. I
bought the one that Moss sells, and thought a lot about where to
mount it on the car to prevent it from shutting off unnecessarily,
and to be easy to reset. I finally decided on the firewall,
passenger side, under the dash, toward the centerline. It is a
fairly rigid panel, within reach of the driver if it trips off on a
pothole or speed bump. Since the rear suspension is stiffer /
jouncier than the front; putting it in the trunk seemed like an
invitation to false tripping.
The wiring path was pretty straight-forward. I ran a couple of wires
from the switch along the harness through the firewall to the fuse
block. I pulled off the white fuel pump wire (the one that shuts off
the pump that isn't the ignition-fed power wire) and put in some
insulated spade connectors so as not to cut off the existing harness
connectors. If the thing fails or I am driving the Baja 1000, I can
bypass the switch / go back to the old wiring. Did some extensive
test driving over neighborhood speed bumps to confirm it wouldn't
trip in normal driving. This could be a problem on a carburated car,
as it doesn't really stop until the fuel bowl is empty, sometime
after the switch trips.
This switch can also serve as an anti-theft device--whack it sharply,
and it shuts off 'til you reset it...
The second thing I did was change the headlights. They had been
sealed beam halogens, but were pretty weak/bad pattern. At night
they were pretty anemic--even in a B, it was possible to drive
"faster than you can see." I'm still running a generator, and don't
plan to upgrade to an alternator soon, and didn't want to upgrade to
something that would burn up wiring, like jumbo driving lights.
(yeh, I could install a relay some day...) I rarely drive where there
is no on-coming traffic, so that doesn't help, anyway. The nice
thing with H4s is that you can select the wattage of the lamp
(commonly available at auto part stores for bikes)--not having a
relay, I went for a lower wattage. I could put in driving lights,
but if they are legally installed, they need to be on a relay with
the high beams.
I got a couple of used H4 type halogen lamps (Carrello?). I had gone
this route on my Alfa GTV-6, and it made a great difference, not just
in brightness, but in pattern. I know they are probably not legal in
Calif., but they are safe. The only downside I've seen is that if
you need to have them aimed by a state repair station, you need to
put back the sealed beams, since they have the three DOT bosses that
the alignment tool needs for location.
