Soemwhat idle tech question.
Where can I get a gas leak sensor, and what type is best for being able to detect different gases?
Any ideas how I could install one in an engine bay of a landcruiser?

WTF - why?

For when my gas system leaks I can prove it, rather than just smelling it...
Really just a safety and peace-of-mind thing while I do some testing.

You would need a VOC sensor (volatile organic compounds) - like a PID (photo ionisation detector). But you are talking about big $$$ - $2K+ for anything that would work.

soapy water in a squirty bottle is like $2

The company that supplies me gas (Origin) have also installed sensors around my shop (it's law now apparently) which connect to the phone line to alert them if there's a leak... it's pretty cheap technology apparently.

physh what sort of car is this on ? You know if you don't have catalytic converters the smell you are getting may be just that - the stenching agent.
In earlier non-cat cars smell of small traces of gas out the exhaust and what it really is occurring is that the stenching agent isn't being burnt off.
Just a thought. check the unions with soapy water from time to time, the installer would more than likely used thread lock on all the fittings - I do and they don't leak after that and nearly 60,000Km of driving
Personally I wouldn't bother getting a detector but that is just my thoughts.
