Can any of you recommend one tester that is reasonable priced?

Detergent and water mix brush on and look for bubbles

Jaycar sells one for about $40 but the air needs to be perfectly still.

So in both options it cannot be tested with the engine running.
With the ignition on (without crank the engine) should be gas on all the lines?
The engine is a V8 3.9 fuel injected.

Soapy water will work with the engine running ,fairly dear tho

Occasional use??

Noses are good for finding the general area of a leak, soapy water lets you home in on the exact spot. Note that a bit of caution is needed, some leaks are big enough to blow the soapy water right away from the leak making it important that you observe the area very carefully as you apply the liquid. The only real advantage of a gas leak detector over a properly calibrated nose is the length variable...

Is this a duel fuel? If so and being injected they are usually set up that they start on petrol and then switch to gas.

This being the case, there would be no gas present with out engine running.

I used to have a 1978 109 Stage 1 running on dual fuel and yes I start it on petrol and then switched to gas but not in this one.
Do you mean for a usually set up as something automatic or just the common norm?
The change over is manual like on the 3.5 carby 109 and so far I never run it on petrol.

Some people believe that should run on petrol offten because the valves seats other said that the 3.9 have strong valve seats.
I was considering to install a valve saver on it.

I have this RR for only 3 weeks.
