1000 tests before the solution may need to be replenished. Dual-Phase Operation: Unique to its design, the LeakMaster NE240 leak tester is a Dual-Phase tool. Phase-one utilizes an inert gas such as Nitrogen to test the integrity of the vehicle’s fuel vapor recovery system by quickly determining if in fact a leak exists.
Do not use with running vehicle engine. Do not perform test near source of spark or ignition. The 12V DC battery source you use to power the LeakMaster NE240 must be in good condition and fully charged.
Accessories: The following accessories are included with every LeakMaster NE240. This EVAP Service Port Adapter is used when connecting to a vehicle's Fuel Vapor Recovery System. It connects directly to the factory service access port on the vehicle. CEA-04 The Cap Plugs Kit is used to seal the intake ducting of the engine under test.
Initial Assembly: The only assembly required of the LeakMaster NE240 is to install the quick-connect fitting to the rear of the water separator / filter, located on the back of the tester. Note: The LeakMaster NE240 arrives filled with a full charge of Smoke-Producing Solution that will last approximately 1000 tests before the solution may need to be replenished.
Because of the EVAP System's volatile fumes, we always recommend you connect the LeakMaster NE240 to an inert gas such as Nitrogen to create the smoke when testing the Evaporative System, in order to prevent creating a flammable fuel mixture inside the fuel tank.

LeakMaster NE240. For this reason, during the ‘Phase-two’ testing, it is strongly recommended that you remove the Schrader Valve prior to introducing the Diagnostic Smoke into the EVAP system.
3. Carefully remove the vehicle's EVAP Service Port schrader valve using a clockwise rotation. 4. Reinstall the EVAP Service Port Adapter onto the vehicle. 5. Connect the LeakMaster NE240 smoke supply hose nozzle tip to the EVAP Service Port Adapter. (This is the LeakMaster NE240 black hose).
Release the push button and begin short pulses to pinpoint the source of the leak. With the LeakMaster NE240 you will find leaks in places you would never have thought to look before. So take a good look in and around the engine compartment where smoke might be escaping.

'open' or remove the valve and introduce smoke in through the tail pipe to verify that these ports are open. 4. Oil Seals and Gasket Leaks: Many oil leaks can be located with the LeakMaster NE240. It is important to understand that the LeakMaster NE240 will only find leaks that will allow air to flow through them.

Component leak testing has endless possibilities; anything from hoses to diaphragms can be tested. Supplied with every LeakMaster NE240 is an exhaust cone adapter that can be used to access any opening from 1" to 3 ½". Simply introduce smoke into the system being tested, seal any inter-connecting ports or passages and look for smoke to exit a leak.

With the LeakMaster NE240 you will actually identify the exact location of where the problem starts and you can do it without ever leaving the driveway.
The entire procedure is performed from outside of the tester. 1. Place your LeakMaster NE240 on its back. (Be careful not to damage the water separator) 2. Remove the drain plug, located on the bottom of the tester, using a ¼ inch Allen-wrench.
