INJECTOR TESTER AND CLEANER
system requires cleaning, an EFI system requires filters capable of 10 micron, this is now available but you
must use a stainless filter any version for petrol will eventually disolve the glue and clog your
funnels and drums certainly does not assist the situation. Some cars are experiencing small balls of rubber out
to the fuel bladder that is also blocking the fuel injectors.
designed to operate with a detergent solution you can purchase, I have found that the solution Part places are

that some spring car team and engine people are saying that the sonic bath is destroying their mechanical
injectors this is a miss informed opinion, the sonic bath will not remove metal it is used for the finest of

cleaning the Injectors remove the filter basket and clean for 30 minutes, the injectors need to be pulsed when
in the bath.
NEVER PUT YOUR HAND IN THE BATH WHEN IT IS
Sonic Bath can be used to clean:
- Fuel Filter
- Jewellery, recommended to change to water
- Carby Parts
INJECTOR PULSE TEST:
designed to simulate operating on the race track and used to provide comparison of different injectors, a
typical VN injector will flow 100cc in 30 seconds, any reading more than 10% either side of that will require

- Remove the filter basket
- If a standard injector remove the end cap
and std disc, if it is a racing one leave it together
- If they are injectors you are racing with
test them first to see the difference.
- Plug one injector at a time into the
Injector Tester and determine if it is operating and the AMP load is not excessive, if the Amp load is
excessive the fuse will blow to protect the unit, if this happens replace the injector.
- Connect up to three injectors at a time and
place in the Sonic Bath, turning both the Injector Tester and Sonic Bath on for 20 minutes.
- Remove the Injectors from the wires, then
with one injector at a time connected to the Injector Tester reverse flush with compressed air.
- Place the Injectors in the stand you have
made and test them
- With the fuel pump operating check
to see that there is no leaks on the injector casing
- Flow test the injectors for 30
