Caprice RWD V8-305 5.0L (1992)
^
Do not use rubber hose within 100 mm (4 inches) of any part of the exhaust system, or within 254 mm (10 inches) of the catalytic converter.
^
In repairable areas, cut a piece of hose 100 mm (4 inches) longer than the portion of line removed. If more than a 6 inch length of pipe is removed,
use a combination of steel pipe and hose so that hose lengths will not be more than 254 mm (10 inches).
^
Follow the same routing as the original pipe.
^
Cut the ends of the pipe, remaining on the car, square with a tubing cutter. Using the first step of a double flaring tool, form a bead on the end of
each pipe section. If the pipe is too corroded to withstand the beading operation without damage, the pipe should be replaced. If a new section of
pipe is used, form a bead on both ends of it also.
^
Use a screw type hose clamp NO. #2494772, or equivalent. Slide the clamps onto the pipe and push hoses 51 mm (2 inches) onto each portion of
the fuel pipe. Tighten the clamps on each side of the repair.
^
Pipes must be properly secured to the frame to prevent chaffing.
NYLON FUEL LINES
Nylon fuel lines are designed to perform the same function as the steel or rubber fuel lines they are replacing. Nylon lines are made to withstand
maximum fuel line pressure, exposure to fuel additives, and changes in weather. There are two sizes used: 3/8" ID for the fuel feed and 5/16" ID for the
fuel return. The fuel feed and return lines are assembled and serviced as an assembly. Quick connect type fittings are used at the ends of the fuel
feed/return lines and at the in-line fuel filter.
Nylon fuel lines are somewhat flexible and can be formed around gradual turns under the vehicle. Nylon lines, if forced into sharp bends, will kink and
restrict fuel flow. Special care should be taken when working with nylon fuel lines. Nylon fuel lines cannot be repaired and can only be replaced with the
proper part number replacement.
QUICK CONNECT FITTINGS
Quick connect type fittings provide a simplified means of installing and connecting fuel system components. Two types of quick disconnect fittings are
used at various parts of the fuel system. O-rings, located inside the female socket provide the fuel seal. One type quick disconnect fitting uses hand
releasable locking tabs. The other type of quick disconnect fitting has a locking tab that requires the use of a special tool.
