Warnings
The vehicle engine must never be started in a closed garage, or any other
sealed structure. Carbon monoxide is produced during operation and is deadly
in a closed environment. Early signs of carbon monoxide poisoning resemble
the flu, with headaches, dizziness, or nausea. If you have any of these signs
get fresh air immediately.
The warnings, cautions, and instructions discussed in this instruction manual
cannot cover all possible conditions and situations that may occur. It must be
understood by the operator that common sense and caution are factors which
cannot be built into this product, but must be supplied by the operator.
The brass components of this product contain lead, a chemical known to the

The components in this Fuel Injection Test Kit enable the testing of the fuel deliv-
ery pressure to the engine. Pressure Gauge (1) connections are made either
directly to the pump, or in-line with the pump and engine.
1. Relieve the fuel line pressure from the vehicle fuel system.
Refer to the vehicle manufacturer’s service manual for instruction on relieving
pressure from the fuel line, testing procedures and connection points, and
normal pressure readings.
2. Use the various fittings and hoses to connect the Pressure Gauge (1) directly
to the fuel pump, as in the case of the VW
®
, or in-line with the fuel pump and
engine for most other vehicles. See connection examples on the next page.
