07 is the earlier generation, I'm not 100% if it's the same, you can pop that rear seat and check for a carpet flap and you'll know in about 2 minutes.
Yes it did, kinda of. I put in the cheapest option from rock auto, and I had a no start about 4 months later when the cheep pump had a hose pop off because there wasn't a clamp, easy 5 minute fix. Then 2 weeks later that hose ruptured and the vehicle wouldn't start at all. I replaced it with an o.e. Motorcraft unit and had bo more issues. So short answer is yes the fuel pump sending unit assembly did fix the problem, it just took a few tries to get a quality part.
Unfortunately no, the mountaineer is requires the fuel tank be removed to access the fuel pump. It's not as difficult as it sounds those are pretty easy to do but they do not have the access plate on top under the seat.
@@larelloneal8990 No, there isn't any way around it, once the tank is out you may be able to cut the floor for the next time (I wouldn't recommend) but even if you're working with just jack stands and hand tools a novice should be able to remove a explorer fuel tank in about 2 hours. It may be a bit time consuming your first time but they aren't all that bad. Fuel line up front, filler at the back, vent hose at the back, an evap line towards the front and an electrical connector about Midway back in the middle of the tank and out it slides.
@@RogueWrenching thank you so much sir for your expertise in the automotive world I had no clue but now with your advice I know exactly what to do thank you again

Yes, but if it leaks it will set EVAP codes. But since it's an easy thing to get to I'm not opposed to reusing the oring. Also make sure you lubricate the oring before install, use clean engine oil or similar.
@Lisa-vi3dx I'm not 100% sure, best thing is to call the dealer and give them the Vin. Also if you pop the cover off the sticker may still he visible on the old pump that will tell you on-board vapor recovery or not.
I'm not 100% sure, earlier years will be very close, but may not have the access hatch under the seat. pull your rear seat up and see if there's a removable access plate under the carpet, if so then yes this should work on your vehicle.
It's located just forward of the fuel tank under the driver's side rear door, it's the large cylinder shaped thing with 2 lines. There are quick connect fittings you will need a tool for, those tools can be purchased off Amazon on or at your local auto parts store. If you need anything else feel free to ask.
That's super frustrating, I'm sorry your having issues, I've yet to coneacross one that couldn't be coaxed off with a hammer and screw driver, that being said here's a few things to remember to maximize chances of success: Use a sledge or other metal hammer mallets and dead blows won't shock the ring as hard. Use a hard handled screw driver so the handle doesn't absorb the shock from the hammer strike. Get as low an angle as you can so you're hitting the ring to turn counter clockwise not down. Try in multiple points around the ring to help break it loose. Hopefully this helps, if you need anything else let me know.
this so much especially on the o lock ring. life saver!!!
I was struggling with the o ring, thank you for the oil tip. Seriously
Glad you found it helpful!
Is it the same for an 07 mariner?

Did replacing fuel pump completely resolve the stalling and or acceleration/idle issues?
Yes it did, kinda of. I put in the cheapest option from rock auto, and I had a no start about 4 months later when the cheep pump had a hose pop off because there wasn't a clamp, easy 5 minute fix. Then 2 weeks later that hose ruptured and the vehicle wouldn't start at all. I replaced it with an o.e. Motorcraft unit and had bo more issues.

Bien explicado mi amigo.
Gracias!
Is it the same with a 2007 mountaineer primere?
Unfortunately no, the mountaineer is requires the fuel tank be removed to access the fuel pump. It's not as difficult as it sounds those are pretty easy to do but they do not have the access plate on top under the seat.
Is there any alternative other than dropping the tank may be cutting a hole in the floor?
@@larelloneal8990 No, there isn't any way around it, once the tank is out you may be able to cut the floor for the next time (I wouldn't recommend) but even if you're working with just jack stands and hand tools a novice should be able to remove a explorer fuel tank in about 2 hours.

Can you use your old o-ring if it's not damaged
Yes, but if it leaks it will set EVAP codes. But since it's an easy thing to get to I'm not opposed to reusing the oring. Also make sure you lubricate the oring before install, use clean engine oil or similar.
O.E. Motorcraft part , need part # ????
PFS478 and PFS468, depending on if it has onboard vapor recovery.
@@RogueWrenching How am I to know if the vehicle has onboard vapor recover? In manual?
@@RogueWrenching Can the part PFS1412 be used? The Motorcraft parts are "out of stock" most places, discontinued I believe.
@Lisa-vi3dx I'm not 100% sure, best thing is to call the dealer and give them the Vin. Also if you pop the cover off the sticker may still he visible on the old pump that will tell you on-board vapor recovery or not.
@@RogueWrenching Thank you
Well done, good video!
Thanks!
Excellent video!
Is this process done the same exact way with the 06 Mariner V6?
I'm not 100% sure, earlier years will be very close, but may not have the access hatch under the seat. pull your rear seat up and see if there's a removable access plate under the carpet, if so then yes this should work on your vehicle.

What where the symptoms that made you swap the fuel pump ??
I actually have a whole video about this on my channel, here's a link: ua-cam.com/video/XJ5P8eGkTG4/v-deo.html
