Safety With the Fuel System
Keep these 12 safety precautions in mind when working with the fuel system.
1. Gasoline is very toxic and dangerous to the skin
and eyes. Always wear OSHA-approved safety
glasses and correct clothing to protect your skin
2. Before working with the fuel system, disconnect
the battery so there is no possibility of producing
a spark that could ignite gasoline.
3. Never remove a fuel filter when the engine is at
operating temperature. When you remove the
filter, gasoline could spill onto the hot manifold and
possibly cause a fire. Let the engine cool down
before working on the fuel system.
4. When checking the fuel pump pressure, make sure
there is no electrical spark that could ignite the
fumes of the open container of gasoline being used.
5. Avoid welding on or near the fuel tank. Remove
the fuel tank and take it to a street rod repair shop
equipped to handle this service.
6. When checking the electrical components in the
fuel system, always use a low voltage battery-
operated tester to eliminate any sparks. Sparks
could cause a fire if near gasoline fumes.

7. When working on fuel injection systems, be sure
to relieve the fuel pressure while the engine is off.
8. Always keep an approved fire extinguisher nearby
(with a Class B rating) when working on the fuel
9. Never clean any street rod parts with gasoline.
10. Never smoke in or around a street rod workshop
11. Always be aware of the possibility of spontaneous
combustion. When oil or gasoline-soaked rags
are left in a pile, they may ignite due to
spontaneous combustion. Always make sure that
such rags are stored in an approved, sealed,
fireproof container. Spontaneous combustion
12. Never use a trouble light with an exposed bulb
when working on the fuel system. If the bulb
were to break, it could ignite either the fuel
or the fuel vapors.
