Help Facet pump
My car is a bugger to start once it's been standing for a few days and it's often idle for weeks on end. It's a Pinto with OE
mechanical fuel pump. I bought a Facet pump reasoning that it would prime the system once I switched on and allow it to start without churning over
for ages on the starter. But, the fitting instructions say wire it in series with an oil pressure switch thus removing any advantage on cold start -
it would still need cranking to gain oil pressure before the pump kicks in.
Any thoughts?

I've wired mine just off the ignition switch
Turn key, pump primes, leave a few seconds, turn key further to starter position
No problem
Wiring through oil pressure is ok but I use an inertia cutoff incase of crash

Where did you source the inertia shut off? Sounds a better plan

if you so to any scrappies you will get one, The ones on Rovers are easy to remove they fitted in the passenger side foot-well behind
centre consol where the consol meets the dash. Held on with either Phillips screws or 8mm head bolts. Remember you need the plug and a few
inches of wire tails.
When you mount it on the car it has to fairly solid bit of structure.

Don't forget to fit a regulator. The needle jets in carbs can only handle about 3 psi before they leak and a Facet dishes out about 6psi or
more. No regulator will simply flood the carbs and result in poor loow speed running and a very thirsty car.

Have decided to use oil pressure switch as recommended but to wire in the low brake fluid test switch which can double as a prime button.

Won't work you would need an N.O oil pressure switch rather than the standard NC.
Rover used this arrangement on some late 1980s car it was a pain in the neck if anything went wrong.
An impact switch (bump switch) is pretty much the standard way of doing things on tin tops.

Wiring it into the oil pressure switch will not switch off the pump in the event of an accident unless the engine stalls. An inertia switch is a much
safer way to do it. Also I had had a couple of problems with Facet pumps due to using the Facet screw in pre filter getting blocked, have found using
a disposable inline fuel filter to be more reliable
