Scribe Line to Identify
45o Mitered Face
Weld/braze adapter fitting to exhaust pipe
(Do NOT use epoxy as shown in this mock-up)
Mitered face in center of pipe
and facing upstream
Check the rules regarding probe locations.
The probe can NOT be located near the
end of the pipe as shown in this mock-up
COUPLER ORIENTATION
For all Quick Disconnect couplers (fuel, coolant, supply, return);
Flow is out of the male coupler and into the female coupler.

NOTE: Contact [email protected] to request couplers (provided free of charge to registered teams).
COOLANT COUPLERS
The black, Coolant Couplers shown above have been discontinued. New couplers, white, slightly smaller,
and also with a ¾” hose barb, MUST BE USED. The new couplers will not mate with the old style couplers.

Participant’s Responsibility
FUEL SYSTEM for EMISSION TESTING
The sled’s fuel tank must be disconnected so that the
test facility’s fuel measuring system supplies all the fuel.
The test facility will supply a low pressure fuel. Teams
need to supply their own external fuel pump and
regulator to ensure that the engine receives fuel at the
correct pressure.
Colder Female Quick Disconnect
OPTIONAL
Colder Male Quick Disconnect
(if have a return line)

Engine
Fuel Supply
Teams must have the Colder Quick Disconnects
installed for both emission events. For the in-service
emission event, take into consideration accessibility of
the QD’s and routing of the external fuel line(s). The
QD’s are not required during the other events in the
competition.
