Shift Cables
D
Control cables should be supported or anchored to prevent sag when suspended
overhead and to prevent movement where the routing bends.
D
On long control runs the conduit should be clamped to supporting structure at
least every 48 inches.
D
Supports should be placed at the end of the straight runs, and not in the middle
of a bend.
D
Care must be taken that the clamps do not collapse the conduit and increase
control friction.
D
Controls should be routed so that they will avoid rubbing, pinching and extreme
heat, cold or vibration.
D
Bend radius to be 6.0 in. minimum.
Section 8 – Fuel and Exhaust
Fuel Systems
Any body installed must be mounted securely to absorb loads and prevent movement
relative to the frame which could cause any fuel system component to be punctured, sep-
arated or otherwise damaged when tested to the applicable procedures of FMVSS 301.
No other installed components or modifications are allowed which could impinge on or
cause distortion to the fuel system with sufficient energy to puncture, separate or other-
wise damage the fuel system when tested to the applicable procedures of FMVSS 301.
Due to the critical nature of the fuel system, anyone making modifications or alterations
to the existing system, except as specified in the Incomplete Vehicle Document or in this
manual, must assume complete responsibility for the systems reliability, performance
and compliance to FMVSS 301.
Assembly of any fuel system components may require application of a lubricant to pre-
vent contamination of the fuel system, only GM lubricant 9985784 may be used.
The fuel evaporative emission control equipment is certified to be in compliance with the
Federal and California Vehicle Emission Standards. Metal fuel lines and fuel tanks have
a surface coating to reduce corrosion on inside and outside surfaces to comply with use-
ful life requirements. All fuel hoses are made of a low permeation multilayer material to
comply with enhanced evaporative emission requirements. Any alterations to systems
or components including materials, hose lengths and their location, except as described
in the fuel fill system modifications section, could void compliance.
The system includes:
D
Fuel tank, fuel level sender, fuel fill and vent hoses and pipes, emission canisters,
fuel feed, fuel return and vapor lines, purge control solenoids, fuel fill cap and
canister vent solenoid.
For these reasons,
NO ALTERATION OF THE FUEL SYSTEM IS RECOMMENDED
Temporary Tank
The temporary fuel container must be replaced with a permanent fuel tank prior to plac-
ing the vehicle into use. The replacement tank supplier and/or body builder is responsi-
ble for certifying evaporative emissions.
The following statement applies to motorhome chassis only.
The unit is fueled during shipping (gas engines only) from a temporary fuel tank which
contains the tank unit for the main tank. The temporary tank is to be removed and
scrapped. Transfer the tank unit with O–ring seal to the main tank. The fuel cap for the
main tank filler neck is the same as on the temporary tank. Remove the tank unit hole
cover and lock ring. Discard
only the tank unit hole cover and the lock ring. Reinstall
the seal, lock ring and the tank unit assembly.
The 75 gallon fuel tank (RPO NJ9) as received has a vented plug marked “For Shipping
Purposes Only”. This plug is to be removed and a solid steel plug shipped in the ship
loose box must be installed in place of the plug removed.
The 75 gallon fuel tank (RPO NJ9) is provided with rear shields to provide protection for
the departure angle shown on the fuel tank arrangement drawing. Any alteration or dele-
tion of these shields requires that an equivalent departure angle of protection be pro-
vided by the completed vehicle.
The following statement applies to commercial models with option B3D only.
The CPI fuel system for standard models is connected to the regular fuel tank. The fuel
system for option B3D gasoline and diesel school bus models is also equipped this way.
A fusible plug is included in the loose parts box. This must be installed into the tagged
hole in the tank to replace a plastic shipping plug.
Fuel Fill
Fuel tank filler pipe location should be so situated and constructed as to prevent gasoline
vapor from emitting to vents of pilot flamed devices and to body and engine compartment
air inlets.
