Eclipse V6-3.0L SOHC (2003)
Use only a hand pressure pump (such as MITYVAC-II or equivalent) with a vacuum/pressure gauge attached. Do not use shop air.
1.
Remove the hose clamp from the fuel return hose on the fuel pressure regulator. Remove the hose from the fitting.
Cover the hose connection with shop towels, to prevent fuel splashing.
Wrap a shop towel around the hose end. If the fuel return port is blocked, pressure will be trapped in the return hose.
2.
Using a hand pressure pump, apply 5 psi into the open end of the fuel return hose.
a.
If the fuel return hose holds this pressure, this indicates that the return line is 1restricted. Continue with Step 3 to determine whether the
restriction is at the fuel pump.
b.
If the fuel return hose does not hold this pressure, continue with Step 3 to verify that the fuel return hose is securely connected.
c.
Reinstall the fuel return hose securely to the fuel pressure regulator, and reinstall the hose clamp.
3.
To minimize gasoline fumes building up in the passenger compartment, open the rear doors and trunk lid (Galant), open the doors and hatch
(Eclipse), and lower the convertible top on Eclipse Spyder models.
4.
Remove the rear seat cushion and remove the fuel pump access cover.
5.
If the fuel return hose did not hold pressure in Step 2, visually inspect the fuel return fitting on the fuel pump to verify that it is securely connected.
If it is securely connected, this campaign procedure is completed. Reinstall the fuel pump access cover and the rear seat cushion.
If the fuel return hose held pressure in Step 2, continue with Step 6.
