To release the pressure in your fuel lines (and fuel filter) you'll need to locate the fuel pump fuse in the fuse box. If you don't have a fuel pump fuse, find the relay that operates the fuel pump. Once you've found the fuel pump fuse or relay, start the car. With the engine running, pull the fuse or relay out. If you pulled the right one, the engine will quickly die. Since it's using all of the pressurized fuel in the system, the fuel lines won't be pressurized when you crack the fittings on your fuel filter. Now that you've relieved the fuel pressure you can remove the old fuel filter. If you didn't do this yet, you must go to the previous step and do it. Very dangerous!
Don't know what you have, but I have a 97 3.9 V6 & fuel pressure calls for 44 to 54 psi
What year? 2001
48 to 54 LBS.
With vacuum line (from fuel pressure regulator) OFF and pinched , pressure should be between 47-54 psi. With vacuum line ON fuel pressure egulator, pressure should be between 38-46 psi.
No less then 48 PSI and no more then 54 PSI
54 LBS. to 62 LBS No lower and no higher.
44-54 psi at idle.
To check the pressure the fuel pump creates. You remove the cap, thread the pressure gage on and turn the Key to ON. On a 2003 the range is 48-54 psi
Key on engine off is 48 to 54 psi.
If 8th didget in vin# is a Z then pressure is--48 to 54 no lower and no higher. If it 's not a Z then pressure is 55 to 62 no lower and no higher.
The only fuel filter on your Honda is in the fuel tank. You have to remove the fuel sender unit from the tank. This is accessed by removing the panel under the spare tire. The suggest service is to measure the fuel pressure with the fuel pressure regulator disconnected and the vacuum line pinched. If the pressure is below 47-54 PSI the filter should be replaced.
With a fuel pressure guage connected, Key on 60-65psi any less & engine will be hard to start possibly cranks wont run. If motor starts than readings should be 54-58psi
