I've recently had a service on my LPG system and during the test the engineer informed me that the LPG control software was reporting the engine was running a little rich (petrol and LPG) and the likely cause would be a small air leak in the air intake system. This problem was not severe enough to trip a fault in the engine management system.

He explained that more air is getting to the engine and the ecu is compensating by adding more fuel.

How can I check for leaks with the air filter housing fitted as it covers the top of the engine preventing a search for a split hose ETC?
