The following diagnosis might be helpful if the vehicle exhibits the symptom(s)
described in this PI.
Condition/Concern:
A dealer may need to perform
a repair on the rubber portion of the fuel supply (suction) lines. The rubber
section of the line could become kinked or collapse. Fuel lines that kink or
collapse may induce a fuel system restriction (high vacuum gauge readings) or
DTCs P0087, P0093, and/or P1093 to set.
If a technician was to suspect
the rubber portion of the fuel feed line collapsing or kinking, replacement of
only the rubber line is
acceptable.
Recommendation/Instructions:
Complete the steps below to
repair the rubber section of fuel supply line:
•Carefully cut, split, and
remove the OEM crimp from both ends of the flexible hose. These crimps can be
cut with a small cut-off wheel. Split the crimp into two pieces (use your
discretion on first cut location, then cut directly across from, or 180 degrees
from first cut). Special care must be taken not to damage the flare on the end
of the steel pipe that will be reused.
•Remove the OEM crimps and flexible
portion of hose from the existing supply line.
•If replacing the rubber
section of the supply line, a 1/2 ID hose meeting SAE specification 100R3 is
suggested. Dealers may be able to find a local supplier for this hose, or can
contact the manufacturer Parker Hannifin. The replacement hose would be a 1/2"
diameter Parker part number 601-8 or H017-8. To find a local distributor the
Parker website can be accessed at
www.parker.com•Use worm type hose clamps (use double
clamps on each end) to attach the replacement hose to the existing pipe.
The
locations of the flexible hoses are pictured below.
