Fuel Pump Tech
Fuel pumps, electric or mechanical, should be chosen carefully. Don't expect a stock mechanical fuel pump to provide enough fuel for a 11 second drag car. There are a
number of quality electric fuel pumps available from a variety of manufacturers. The pump should be paired with the an adjustable fuel pressure regulator to allow setting
the desired fuel pressure. Most carbureted applications generally require a pressure setting of 6-8 PSI. Regardless of selection, any electric fuel pump should be mounted
as close to the fuel cell/tank as possible.
While we're on the subject of electric fuel pumps, make sure the pump is wired properly. Too small of gauge wire, over the length of the car, is subject to a condition
known as “voltage drop”. This can prevent the pump from receiving the 12 volts needed for proper operation. Check the lead wire directly at the pump with a volt meter
while the pump is running. If there is a problem, a properly installed relay can correct it, and assure that the fuel pump receives adequate voltage.
Fuel lines should be properly routed to provide the shortest, safest route to the carburetor. Avoid exhaust components or any other source of heat. Frame rails and/or
chassis tubing represent a reasonably straight safe path, where the lines can be secured with mounting clamps. Proper line size selection depends upon the horsepower,
and the fuel pump manufacturer's recommendations. Original fuel line should be replaced with at minimum, 3/8" aluminum tubing or -8AN stainless steel aircraft type
hose for dual duty street/strip cars. Drag race vehicles that have in excess of 500 horsepower require -10AN stainless line. Fittings should be sized accordingly. Under any
circumstances, do not use hardware store fi ttings. They may be affordable, but are very restrictive.

Champion Spark Plugs
Spark for a weekend bracket warrior or a 600+ cu. in. strip terror. Plugs use an exclusive
chromium-nickel ground electrode for superior erosion resistance and extended life. Champion’s
copper core, center electrode enhances thermal capacity for peak performance at all engine
speeds. A triple-coated shell with anti-seizing coating makes plug removal easy. Plug tempera-
ture is self-adjusting for maximum anti-fouling performance thanks to a zirconia enhanced
insulator. Available for many applications, please call with your specifi c needs. See page 671 for
spark plug application chart.
