Specifications

Pressure Gauge

0~100 PSI

•  0~700 kPa

IMPORTANT SAFETY INFORMATION

1.  Do not use on diesel engines.

2.  Stop engine, loosen gas cap and relieve fuel 

pump pressure (see service manual) before 

opening fuel line.  Do not change fittings with 

engine running or fuel line pressurized.

3.  Do not overtighten fasteners.  Brass fasteners 

or hollow fasteners may be easily damaged by 

overtightening.  Tighten enough to get a good seal.

4.  Before testing fuel system, verify all 

connections are tight to eliminate leaking.

5.  Gasoline is highly flammable.  Do not smoke or 

test near an ignition source.  Do not allow gasoline 

to come in contact with the hot manifolds or 

other engine components.  If additional lighting is 

required, use only an explosion-proof drop-light.

6.  Do not drive the vehicle while under test.

7.  Before testing, review and follow instructions from 

the vehicle manufacturer’s service manual.

8.  After testing, turn engine off and depressurize 

system before removing test components.  

Place absorbing cloths around fittings before 

disconnecting.  Wipe up any spilled fuel 

immediately.  Place cloths in a fireproof container.

9.  Clean all testing components of 

residual fuel before storing.

10. Wear ANSI-approved safety goggles and 

heavy-duty work gloves during setup and use.

11.  This product is not a toy.  Do not allow 

children to play with or near this item.

12. Use as intended only.

13. Inspect before every use; do not use 

if parts are loose or damaged.

14. Perform service in a well-ventilated location.  

Not only are gasoline fumes flammable, but 

carbon monoxide is produced by a running engine.  

This is a deadly gas that you cannot see or smell.

15. Maintain product labels and nameplates.  

These carry important safety information.  

If unreadable or missing, contact 

Harbor Freight Tools for a replacement.

16. The warnings, precautions, 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.
