Is my fuel pump bad 1999 ford explorer shoc 4.0. Lots of pictures on the replacement

Time for filter

 

[donalds]

Remove with disconnect tool

Clean everything put a ill Vaseline on the tips if the filter ends to help seat the o rings inside
The connector
Snap the filter on the lines clip the clips on the lines snap filter in its holder

Fuel pressure stays at 69 _ 70 running
65 when you shut it off and stays there well I left the gauge on for an hour never moved
Took it on a 60 mile run worked great better throttle response

Good job. Congrats!

Well done, detailed pictures, and the lubricating of the fuel line connection was the most helpful step.

My thinking was the fuel line connectors have o rings I don't know if I can replace them so I lubed them so I had no damage and leaks

 

[CDW6212R]

Yes, part of why they are hard to get apart is lack of lubrication of the o-rings and the rest of the connections. I've sprayed those most of the times that I have removed the fuel tank. You won't have problems with that truck if the tank needs to drop again. Your son will remember the time he spent working on that with you, more than the small details of how it got done.

Good job & write up!

I just replaced the pump and sending unit in my daughter's 94. I removed the left rear seat, pulled up the carpet and cut a hole in the floor above the tank. Bent the metal back out of the way, disconnected the fuel lines, then unplugged the connector by the left rear leaf spring, popped of the lock ring and pulled the unit out. Installing is just the opposite of removal. When I was done, I bent the piece of the floor I'd cut back into place and sealed it with duct tape, put the carpet and seat back. Done. The only time I had to crawl under the truck was to unplug and plug the electrical connectors. Took 2 hours. Lots of info on the internet on this subject.

Clean the wire plug

If you wanted test your pump BEFORE dropping the tank, put your multimeter set for resistance across pin 6 and 7, which are the middle two on the bottom row in the photo above, and if it shows 10 ohms or less the pump is still good..

More than 10 ohms, or most likely infinite, and the pump is shot and you're on the right track.

@Spuddy - Thanks for the ohm test info. Good stuff. Regarding the electrical connector you mentioned, can it be accessed (in order to disconnect it and then do the ohm test) without dropping the tank? I.e., can you get your hands up in there... is there enough room to do the ohm test?

 

[donalds]

I tested mine by pulling the relay and using the socket
To test with my meter and finally used A jumper wire to just let the pump run for a hour with the engine off testing fuel pressure at the same time

That connector is attached to the frame rail next to the left rear wheel. You can reach it with the wheel off and look up just inside the body inner fender, the wire loom for that runs from the fuel pump over to the frame there.

Put truck on Jack stands
Remove driver's side rear wheel

Hello, may I ask why the jack is on a board? Is this because the ground isnt level or is this to make it harder for the jack to kick out? Just curious if I should be using boards as well.

 

[Fix4Dirt]

more stable, less likely to indent the ground, and safer in that it wont slip on the gravel (ive slipped so much on tht stuff when its wet... wood, not so much)

Yep to keep it from sinking in the ground
Or dent the gas tank

i wonder if soemones done it with a trans jack before, just with longer straps. luckily my dad is super cool and we do all this stuff together (im still in school, so still learning!!) but i wonder if it was a solo job could a trans jack make it any easier to line up etc when reintsalling, as then no one has to hold it to ensure its stable

 

[donalds]

It can be done solo but its way easier with 2 people
