2) Fuel Lines
PROCEDURES/SPECIFICATIONS:
Firmly attached. No leakage, seepage, abrasion, or
						  chafing. Must be 1113/16
						  inches (300 mm) from any part of exhaust system that contains exhaust gas or be
						  safeguarded by a heat shield. Inside engine compartment, the chassis
						  manufacturer's standard shall govern separation and shielding between parts
						  designed by chassis manufacturer.
Exception: Fuel system components on diesel powered
						  engines that are located within four inches of a component containing exhaust
						  gas shall be shielded.
REJECT VEHICLE IF:
Fuel lines are cracked, leak, insecure mounting,
						  damaged, clamps missing, mount clips missing or not separated or not shielded
						  properly (if applicable).

8) Alternate Fuel Systems (LPG or CNG)
PROCEDURES/SPECIFICATIONS:
An alternate fuel system which is no longer in use must
						  be completely removed from the bus.
A) Carburetion Equipment
A fuel filter is required on alternate fuel
						  systems.
B) Container Installation
i)
Compressed or liquefied gas containers shall not be
						  mounted in the passenger or driver's compartment.
ii)
Container valves, appurtenances and connections shall
						  be mounted in an enclosed compartment.
iii)
Containers shall be located at least 36 inches from the
						  entrance door and any emergency exit. Due to the smaller size of Type II school
						  buses, space limitations may sometimes make it impossible to locate a fuel tank
						  further than 36 inches from a exit. A Type II school bus has a gross vehicle
						  weight rating of 10,000 pounds or less [625 ILCS 5/12-800 ] as defined in
						  Section 12-800 of the Illinois Vehicle Equipment Law. If the original fuel tank
						  for a Type II bus was located within 36 inches from any exit, the alternate
						  fuel container may be located in the same location as the original tank.
C) Identification
The fuel identification decal (see Section
						  443.Illustration D) shall be displayed near the rear bumper and visible from
						  the rear of the vehicle. The decal shall not be placed on any black portion of
						  the bus body.
D) Pipe and Hose Installation
i)
No fuel supply line shall pass through the driver or
						  passenger's compartment.
ii)
The pressure relief device shall be fabricated so that
						  in the event of stress, the pipe or adapter will break away without impairing
						  the function of the relief valve.
iii)
If installed, the adapter connecting the piping system
						  to the pressure relief device shall neither touch nor restrict an movable part
						  of the pressure relief valve.
iv)
The relief valve discharge piping system (piping
						  system) must not be reduced at any point from the relief valve to the point of
						  release into the atmosphere.
v)
The piping system shall be routed to minimize sharp
						  elbows or bends. Installation of any commercially available piping installed to
						  meet the manufacturer's specifications is acceptable. Any fittings that
						  restrict the flow of discharge are prohibited. From the pressure relief device
						  adapter to the atmosphere, the minimum inside diameter of the piping must
						  measure at least 3/4 of an inch.
vi)
The piping system shall neither block nor hamper the
						  operation of any window or door. The piping system shall preserve widths of
						  passageways, aisles and emergency exits.
vii)
Every portion of the piping system shall be gas tight
						  (except the outlet) and shall be able to withstand forces from the discharge
						  when the relief valve is in full open position. If for any reason the discharge
						  outlet becomes blocked, the piping system must be capable of holding the full
						  system pressure.
viii)
To facilitate the removal of accumulated waste, a drain
						  cock shall be installed at the lowest point of the piping system. The drain
						  must be capable of being held open manually and close automatically to prevent
						  expelling LPG if discharged through the relief valve. A weep hole, or other
						  opening that may result in discharged LPG flaming beneath the bus is
						  prohibited.
ix)
The portion of the piping system that leads upward to
						  the atmosphere shall be installed either inside the passenger compartment, on
						  the outside of the bus, or in the body wall between the inner and outer "skins"
						  of the bus body.
x)
Piping on the outside of the body shall be shielded
						  below the window line to prevent "grabbing hold" or "hitching to". However,
						  discharge piping that is located between the windshield and the vent window at
						  the left front corner of the body need not be shielded.
xi)
Any portion of the piping system that is installed
						  either inside the passenger compartment or inside the body wall shall consist
						  of one piece originating below the bus floor and exiting outside the bus roof.
						  Every hole where piping passes through the floor or roof shall be
						  sealed.
xii)
The piping system must terminate above the eave lines
						  of the bus body.
xiii)
The outlet of the piping system shall be located at
						  least 36 inches from the air inlet or outlet of a ventilator or similar device
						  installed on or near the roof. A "similar device" includes the fresh air intake
						  of a heating, ventilating or air conditioning system. It does not include a
						  side window that opens near the roof.
xiv)
A rain cap is required where the piping system exits
						  into the atmosphere to minimize water or dirt from entering into either the
						  relief valve or its discharge piping. Installation of any commercially
						  available rain cap installed to meet the manufacturer's specifications is
						  acceptable. The cap shall remain in place except when the relief valve
						  operates. The cap shall be installed to minimize the entrance or water or dirt
						  while the vehicle is in motion.
xv)
The discharge piping system on a special education
						  school bus shall conform to all provisions of this Part.
REJECT VEHICLE IF:
Propane relief valve/piping system is not properly
						  installed. Alternate fuel system does not meet requirements listed
						  above.
b) GRAB HANDLES
1) Exterior
Not required.
2) Interior
PROCEDURES/SPECIFICATIONS:
Shall be of stainless clad steel, installed inside
						  doorway, solidly attached on left side, and as long as practicable.
As instructed by an officer of the Department, draw a
						  1/2 inch hexagon nut attached to a string through the junction where the grab
						  handle attaches to the lower stepwell.
REJECT VEHICLE IF:
Missing or not solidly attached.
Nut becomes lodged on grab handle. (Retrofit kit is
						  required.)
c) HEATERS
PROCEDURES/SPECIFICATIONS:
Must be capable of maintaining inside temperature of 50
						  degrees. The heater hoses shall be supported to guard against excessive wear
						  due to vibration and shall not interfere with or restrict the operation of any
						  engine function. Any hose in the passenger compartment shall be protected to
						  prevent injury from burns in the event of rupture. Primary heater shall be a
						  high output fresh air type. Heater must be padded if not protected by
						  seat.
The secondary heater may be a recirculating type and
						  located so as not to interfere with aisle space.
REJECT VEHICLE IF:
Heater is missing; in poor working condition; defective
						  hoses, supports or baffles; not firmly attached or padded when required.
d) HOOD
PROCEDURES/SPECIFICATIONS:
Open hood and inspect safety catch and hinges for
						  proper operation. Close hood and inspect for proper full closure. Manually
						  inspect latches or remote control for proper operation.
REJECT VEHICLE IF:
Hood does not open or hood latches do not securely hold
						  hood in its proper fully-closed position. Secondary or safety catch does not
						  function properly. Hinge is broken, missing, or not attached to body.
e) HORN
PROCEDURES/SPECIFICATIONS:
Dual electric horns shall be provided giving an audible
						  warning at a distance of 200 feet and shall be conveniently controlled from the
						  operator's seated position. (Section 12-601 of the Illinois Vehicle Equipment
						  Law)
