The service procedures defined in this ma-
nual, when followed, have been found to be a
safe and efficient process to repair the fuel

IMPORTANT
It is important to remember that there may be a
combination of Metric and Imperial fasteners used
in the installation of the IMPCO fuel system.
Check to insure proper fit when using a socket or
wrench on any fastener to prevent damage to the
component being removed or injury from “slipping
off” the fastener.
The fuel system utilizes fuel lines and hoses with
high pressure connectors. Always use a wrench
of the proper size and torque to the correct value.
For hoses with swivel fittings, be sure not to turn
the fixed fitting which may cause a twisting or
kinking of the hose, possibly resulting in fuel line
restriction and/or leak.
Always leak check any fuel system con-
nection after servicing! Use an
electronic leak detector and/or a liquid
leak detection solution. Failure to leak
check could result in serious bodily in-
jury, death, or serious property damage.
