Fuel Pressure Check
 

OK, I'm new to my 2000 Elantra. So stupid question here: How do you check the fuel pressure on this car? I can't seem to locate any sort of port (schrader valve) to connect the "usual" pressure gage.

Can someone help on this? Thanks.

FUEL PRESSURE TEST

Safety glasses must be worn when performing the service as follows.

1.Reduce the internal pressure of the fuel pipes and hoses by the following procedures.
a.Disconnect the fuel pump harness connector after removing the rear seat cushion
b.Start the engine and after it stalls, turn the ignition switch to the OFF position
c.Disconnect the battery negative (-) terminal.
d.Connect the fuel pump harness connector.

2.The fuel filter is located in the left side of the rear quarter of the engine compartment.

3.Remove the single tie-wrap that secures the fuel pressure line to the fuel return line.

4.Remove the electrical connector from the master cylinder reservoir below.
Before proceeding to the next step, place shop rag over fuel filter to capture fuel spray.

5.Move shop rag enough to expose bolt on top of fuel filter, remove bolt and line from filter.

6.Using the fuel pressure gauge, gauge connector and gauge adapter (09353-24000, 29000), install the fuel-pressure gauge to the fuel filter. Tighten the bolt to the specified torque.

7.Connect the battery negative (-) terminal.

8.Start engine and check for leaks. If no leaks are present, continue with fuel pressure test (at curb idle speed).

9.Connect (disconnected) the vacuum hose from the pressure regulator (and plug the hose end). Measure the fuel pressure.
