inertia cut off switch
Is it true that you need an inertia cut off switch for the fuel pump (for SVA) if you have fuel injection ?
cheers

I don't know whether you NEED 1 to pass - but surely it's a good idea with FI running at 3 - 4bar?
I installed mine simply to make me feel a bit better. I can only imagine that if you have an accident and are trapped in the car it will be very
comforting to know that fuel isn't gushing everywhere at 3bar pressure just because the pumps still running.
It just feels like a sensible thing to do. I paid £5 from a scrappy for one off a Rover 214/216/414/416 etc...

With my Emerald, the ECU shuts down the fuel pump when the engine isn't running. Only time it's active when the engine isn't is the
initial short prime when you turn the ignition on.

Even the DIY megasquirt does this, as do most OEM ECU's. What it doesn;'t protect against is if the engine carries on running for a while
after an accident.

Hang on.... If the engine is running then the fuel supply isn't severed so surely there is no immediate danger.... If the fuel line is severed
the engine stops so the ECU shuts off the fuel pump...QED.
Plus there is nothing in the SVA manual about a seperate fuel cut off.

No. Could be the return line that's severed....in which case the engine would keep running until the pumps have emptied the tanks...

at 3+ bar all you need is a pin hole for a really hot fire.

The pressure line on my 16vGTE failed, a 6" length of rubber pipe that fits between the pump and the steel fuel line under the boot floor. I
started the car up and noticed it was running quite roughly, but started to do a 3 point turn in the road and a bloke came running up to me waving his
arms and shouting. Stopped the car and got out, to find a good gallon of fuel sprayed all over the road, gently eating into the tarmac.
Moral of the story is an engine can still run with a punctured pressure line...

The switches are so cheap, and easy to fit, it is never worth the risk not fitting one.
Mine came from a Punto Mk2 (inside the LH A Pillar base), the easiest are from P106/Saxo's, LH side of the engine bay on the bulkhead
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

I have been well and truly effed off with the switches in the past so I for one will NOT be using one!
Hitting bumps really hard sets them off, not what you want when trying to press on down the lanes!!! My XR4x4 does this occasionally, usually after
minor airborne excursions, and it is very annoying.
(ok, i will admit not as annoying as being on fire!)
The likelihood of my aeroquip fuel lines failing in such a way that they would not stop the engine is low enough that I won't worry about it.
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

The switch in the Rover 214/216/414/416 (pre 25/45 design change) is found inside the car. If you're sitting in the drivers seat it is behind
the trim panels by your left knee.
It's inside the centre console and mounted just below and to the right of the radio.
I have had my Locost on the road for 12 months/4000 miles and it's never tripped out. But it does work - 'cause I test it occasionally
(usually when I'm bored and the bonnets off the car )
