Fuel Line/Quick-Connect Fitting Precautions
The fuel line/quick-connect fittings (A to J) connect following:
A: fuel feed hose (K) to fuel feed pipe (high pressure fuel pump) (L)
B: fuel feed hose (K) to fuel feed line (M)
C: fuel tank unit (N) to suction line (O)
D: fuel tank unit (N) to fuel vent line (P)
E: fuel tank unit (N) to fuel feed line (M)
F: EVAP canister (Q) to fuel vapor line (R)
G: breather line (S) to suction line (O)
H: breather line (S) to fuel filler pipe (T)
I: one way valve tube (U) to fuel fill pipe (T)
J: one way valve tube (U) to fuel fill pipe (T)

When removing or installing the fuel feed hose, fuel tank unit, fuel tank, EVAP canister, or when disconnecting/connecting the quick-connect fittings, pay attention to the following:
The fuel feed hose, the fuel line, and the quick-connect fittings are not heat-resistant; be careful not to damage them during welding or other heat-generating procedures.
The fuel feed hose, the fuel line, and the quick-connect fittings are not acid-proof; do not touch them with a shop towel which was used for wiping 12 volt battery electrolyte. Replace them if they came into contact with 12 volt battery electrolyte or something similar.
When connecting or disconnecting the fuel feed hose, the fuel line, and the quick-connect fittings, be careful not to bend or twist them excessively. Replace them if they are damaged.




A disconnected quick-connect fitting can be reconnected, but the retainer on the mating line cannot be reused once it has been removed from the line. Replace the retainer when:
Replacing the fuel feed pipe (high pressure fuel pump)
Replacing the fuel line
Replacing the fuel pump
Replacing the EVAP canister
Replacing the fuel filter
Replacing the fuel tank
Replacing the fuel fill pipe
The retainer has been removed from the pipe
The retainer is damaged

Use the same manufacturer retainer and the same size retainer when the replacing the retainer.
