I'm on to my second electric fuel pump,

The first was a pieburg electric roller vane style pump, It was low
preasure and required no regulator with 2 * 36DRLAs.

When the plastic fittings snapped I then changed to a FACET blue top
pump, this is a much bigger high volume pump, but still low preasure,
but this does require a regulator. I have a filter king regulator as the
pump has too much preasure and the engine can flood after 5 mins of
idleing without it. It is one of those noisy types particularly when
bolted on to the bulkhead.

As for wireing up electric pumps, the recomended way, and that used by
all manufacturers for all injected and some carbed engine is to use an
inertia switch. These switches brake contact in an accident and thus
stop fuel being pumped everywhere. All of them can be reset, but some
can also be tripped on purpose, thus acting as a simple anti theft
device.

As for using an oil preasure switch, this is a good idea, but you may
need a relay and you will probably need an override switch so the pump
can run before you have any oil preasure, thus enabling you to start the
engine.

A relay on this swich is also good for any heated rear window, so you
canhave the HRW on when the engine is running.
