One little safety warning: Wear safety glasses!
If you're unsuccessful at bleeding off the fuel pressure, it sprays ALL over the place.
And one possibly useful tip: to relieve the agony of gasoline in your ear, pour baby oil in on top of it to dilute it.

HELP!
I am having a hard time removing the fuel filter. I took it to a shop and they couln't remove it. They said the spring o-ring inside the line is broke and I will need to get a new spring. Where do I get that? The parts store showed me plastic o-rings and couldn't help...

As for the fuel filter, you can pick up that tool cheap and try it yourself, or even "rent" one from AutoZone. You put down the deposit then get your money back when you return the tool. I'd think that a broken spring wouldn't keep the line from coming off. Seems to me that it would make it come off easier... but of course, I'm no expert. If the spring *is* broken, JBG has replacement fuel lines that should solve the problem. I've never seen a replacement spring
Good luck!

Folks: Hello. I ran across this thread while searching for info on how to change the fuel filter on my '96 351. It appears to be a similiar process as changing it out on my '91 F150-Inline Six, but what I can't figure out is how to de-pressureize the system? On my F150, there's a fuel cutoff switch on the firewall on the driver's side. I push it in and run the truck 'till it stalls. I can't seem to figure out how to do it on the Bronco, though.

the same switch is under the kickpanel on the passenger's side. At least that's where it is on my '93 
it's an inertia switch, so for those of you who don't already know, you have to trip it using a screwdriver to lift the little red button. after 20 seconds or so, the engine should stall and your system will be depressurized. Hope this helps.

You can trip the shut off switch while running the engine, or disconnect the wire harness from the fuel pump amongst other things. Alternatively, you may not bother depressurizing the system since you'll spill a bit of gasoline, anyhow. Just make sure you don't ignite the spill, and it won't get into your eyes, nose, mouth, etc.

You can bleed pressure off at the fuel rail pressure port. On the fuel rail it is a schrader valve on the front of the fuel rail with a plastic cap. Be careful fuel will spray out a little 
. I couldn't get the fuel filter connection on my 93 apart without bleeding pressure. Mine required a tool to release inner spring retainer at filter connection.

The safest way to depressurize the fuel line would be to remove the fuel pump relay in the relay/fuse box near the driver side hood hinge. Then crank the engine. Disconnect the negative battery terminal. Also loosen the gas cap and make sure that the front of the truck is higher than the rear of the truck.
This procedure will be the safest and will insure that the amount of gas released will be minimal .
Oh--and no smoking

Cool, thanks for the response. I'm curious. Everywhere I read, they all recommend disconnecting the negative battery cable. Why is that?

When opening a fuel system that may still be pressurized--you dont want any wiring that is still energized--that could be a possible source of igition.
And be sure to change the fuel filter away from any pilot light/furnance and have the vehicle in a well ventilated area.
And wear eye protection!!

Live wires! That makes sense.

Why is this thread still going and confusing people? It's a simple enough answer, there is a special tool set to take the filter off, it's easy to use, and it's cheap. The set consists of plastic "circles" of different sizes and colors; you take the correct size tool and slide it into the filter and it releases the one-way spring that is inside the filter and it slides right off. Installation is the reverse except the tool is not needed, you just slide the filter on and the one-way spring catches and locks down. The best way that I can explain it is that it is sort of like the clip that holds the headlight **** on; in theory, anyway. It's a one-way deal that needs a tool of some sort to remove, but not to install.
It is also helpful to release the fuel pressure, so you don't get a faceful of gasoline when you remove the filter; but I have done it without releasing the pressure and it wasn't that bad, not too much gas came out.

I found the fuel cut-off, by the way. On my '91 F150, its on the firewall behind the emergency brake pedal. On my '96 Bronco, it's behind the passenger kick panel. I simply turned the truck on, popped up the button on the switch and voila, no more fuel to keep it running.

The problem I have on my '96 351 Bronco is the same as ojosdestranger had. I CANNOT get one end of the filter loose. I can get one end off so I know I'm using the tool correctly. I have not taken it to a shop yet but that will be my next option.
Does anyone have any hints on fighting the springs if they get to be very stubborn? I have used penetrating oil to try to loosen them but that didn't work. Obviously using heat isn't a good idea. The truck runs fine so it's not like I have to replace the filter now but I sure would like to get a new one on there for piece of mind. But if it means I will have to buy a new fuel line for it then I might just take my chances with the old line.
Thanks,
Marshall

Could someone explain this procedure for me. Also, is a screwdriver, even a tiny one, going to fit between the filter and the line housing or do I need to bend or what. Thanks in advance.
