How do you get the lines off the fuel filter to change it. i've got the tool to do it with but it still won't come lose. what am i doing wrong?

 

Fill us in ... what year and engine at least. On my 90 I did not need the tool ... had it anyway. Mine had two lock clips that needed to be pulled out before the hoses could be pulled off. If your new filter came with these you probably don't need the tool ... if it does, hopefully you give the info needed and someone with that experience can help you.

 

On your 1992 F150

In-Line Fuel Filter

CAUTION:
If the fuel filter is being serviced with the rear of the vehicle higher than the front, or if the tank is pressurized, fuel leakage or siphoning from the tank fuel lines could occur. To prevent this condition, maintain the vehicle front end at or above the level of the rear of vehicle. Also, relieve tank pressure by loosening the fuel fill cap. Cap should be retightened after pressure is relieved. Depressurize the fuel line system at the Schrader valve on the engine fuel rail. If vehicle is warm, change the fuel filter before the pressure rebuilds.


Removal

1. Shut engine off. Depressurize fuel system
2. Disconnect battery ground cable.
NOTE:
On vehicles equipped with EEC, when the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the EEC processor relearns its adaptive strategy. The vehicle may need to be driven 10 miles or more to relearn the strategy.
3. Raise vehicle on hoist.
4. Remove filter-to-fuel line retainer clips.
5. Remove push connector fittings at both ends of the filter as outlined in this section.
6. Remove two nuts from filter studs and remove filter and bracket assembly.
NOTE:
It may be necessary to unclip and move parking brake cable.

Installation

Note that the direction of the flow arrow points to the tab of the bracket against which the filter rests.
1. Install filter and bracket assembly and two nuts. Tighten nuts to 11-15 N-m (96-132 in-lb).
2. Install push-connect fittings onto filter ends as outlined in this section.
3. Snap on filter-to-fuel line retainer clips. Long legs of clips go onto fuel lines.
4. Lower vehicle and connect battery ground cable.
5. Turn ignition switch from OFF to RUN position several times without starting engine. Check for fuel leaks.

1. Open safety clip.
