2003 Montero Fuel Pump Replacement

Swapping out the fuel pump unit and the filter on my 2003 Mitsubishi Montero. Fairly easy job, just messy.
Replacement fuel pump unit part# 950-0180 (Denso - OEM)
Replacement fuel filter part# 043-3009 (beck arnley)
Tools needed:
* 10mm socket
* 8mm socket
* Flexible joint extension
* Nose pliers
* Flat head screwdriver
Denso fuel pump kit came with extra stuff, but I ended only using the O-ring, new strainer and the rubber fitting for the fuel pump. Everything else I reused the old parts as they were still in good condition per my visual inspection.
Cycle the key couple times before starting the engine for the first time to make sure the fuel pump is primed and fuel pressure is there.

Fantastic Video!! and Thank You for posting it.

Thanks for filming this.

You are the man!!!! Thanks for doing this!!

thanks! enough shown so we know what parts to procure before opening it up!

[@robinsonmarine2946]

Excellent

[@garyreid9842]

When you replace the unit should you apply oil or some other lubricant to the upper o ring gasket that seals between the fuel tank and the fuel pump/ filter module. I replaced my fuel filter on my NP Pajero a couple of days ago and now have a lingering fuel smell. I rechecked for physical leaks and all hoses replaced correctly. I suspect my old O ring may be not 100% sealing the fuel vapour.

[@01170154]

Lube the o-ring with a little gasoline

[@chapinhack]

Very helpful, the only question I have is how did you came to the conclusion it was the pump and not something else, am leaning towards that in my montero but would hate to change that and not being the problem. Just a question is all

[@juanlanda2441]

All one handed😀.

[@Georges5104]

Good job

[@lenineder]

Excellent video. I think I will need to do this very soon. Did you have to disconnect the fuel pump relay to remove the fuel pressure in the system? Thanks in advance!

[@01170154]

Didn't need to

[@sleepyhollow783]

Very helpful. Thank you for posting. My Montero's fuel gauge is not reading accurately. Reaches Full but will sink to 3/4 or half tank. Is the float part of the pump assembly, or is the float elsewhere in the tank?

[@01170154]

The float is in separate part. Under passenger side floor carpet

Great video dude, would you happen to know what p0441 error code is? Popped up recently says it's a fuel problem....

[@81recinos]

Is there access for fuel sending unit on the montero 2002?? Or you have to remove the thank??

[@MrDeathseraph13]

Top bloke, thanks for this! Any error codes after doing this mate?

[@01170154]

No error code. Ran even better

Thumbs up for this.

My gen 3 Montero turns over but won’t start . All of sudden happened today . I think it’s the fuel pump because I can’t hear it come on .. should I be able to hear it come on ?

[@pepegarcia120]

Where did you get the fuel pump? it says it was discontinued

[@LacosteBlanc]

good video but i missed a lot of info on the fast part

[@biok2006]

Thanks for the video but can you help me where are located the relay for the fuel pump? Montero 2002

[@flexbuffchest21]

Hello, I replaced my fuel pump with the same parts as you. Before my car would just crank and not start. After replacement the car starts up but it takes a little longer to start. Sometimes It cranks a tiny bit more then it used to and other times has a long crank time before ignition. Any ideas?

[@01170154]

Did you replace the filter too? How's your battery charge?

[@flexbuffchest21]

@@01170154 yes I did everything like you did. New filter, pump and strainer. Haven’t checked my battery but it is brand new

[@01170154]

@@flexbuffchest21 then it's likely to be ignition related. Maybe new spark plugs will help

[@flexbuffchest21]

@@01170154 I took the pump assembly back out and replaced the O ring. That was the fix. The old one was torn so mush not of been able to maintain and build pressure

[@hassenusman7857]

Can I reuse the the plastic part? Instead of replacing it?

[@user-zt8vj4bu9s]

Hello,my montero is 2003 model limited,and it is not fast,i think its have porblem,and this problem would be petorl?

[@andrewlluen8239]

great video by the way, did you hear a noise coming from your fuel pump I hear this like vacuum type noise or a humming sound coming from the fuel pump

[@01170154]

I heard it, but it wasn't consistent. So I knew the fuel pump was weak

[@andrewlluen8239]

@@01170154 I mean it's loud enough that I can hear it from the driver seat then going under the car I assumed it was coming from the engine bay but the noise was coming from like the gas tank area.

[@01170154]

@@andrewlluen8239 the fuel pump is right under the rear passenger seat so you can hear it pretty clear

[@andrewlluen8239]

@@01170154 so I can hear it, does that mean I should change it out, it's kinda loud, like if I'm at a red light and it's quiet outside I can hear it in my cabin.

[@01170154]

@@andrewlluen8239 you should be able to hear it before you start the car when it's priming. Once the engine runs it should keep running, but will be barely noticeable as the engine noise is louder

[@perrismcclanahan5844]

Did you have any check engine lights before you changed the fuel pump? I'm getting a p0171 and p0174 in my 04 and was wondering if that's why you changed your fuel pump.

[@01170154]

No CEL, but engine would die during driving. I just replaced spark plugs and filter so the problem must've been the fuel supply

[@zacharylopez9711]

Hey I just got a p0171 code. Did you get yours fixed? If so what was the issue?

[@lennyfletcher3557]

Just trying to pull mine out after buying the car from a guy that didn't take care of it and he's never done the fuel pump... having trouble taking the clip with the little blue buttons on either side. Is this a simple clip and it's just seized on there or is there some sort of trick to taking it off

[@douglasewell]

They make a special tool for it . If you don't have that you have to seize them together hard and pull.

[@Josue-gy7vg]

Is Montero limited?

[@dee0en]

How do you remove the motor off the assembly? Do you simply pull it out?

[@01170154]

Yes, just pull it out

[@dee0en]

thanks Buddy!

[@perry8498]

When you replace the pump what was the noticeable difference

[@01170154]

Starts up faster and no more engine dying while driving

[@perry8498]

Wawa Iki ok I’ve just had a induction clean and it’s still blowing black smoke but it surges when it starts to smoke so I’m looking at the suction valve now

[@dekillful]

Is this 4m41 diesel?

Is this under the driver rear seat?

Is the access point on a 2006 the same?

Yes

[@ps4pgames821]

is fuel pump for Pajero 2010 the same for for 2002?

[@01170154]

I wouldn't know, Mitsubishi stopped selling Montero here in 2006 but I would imagine the replacement steps are very similar to Gen3

[@adamkim3583]

Great video thanks! I don't have much automotive experience but with this video I think the job is doable ;-) It appeared that the clips that keep the housing together were tricky to get apart. Any tips how how to separate the housing without breaking clips?

[@01170154]

I used flat head screwdriver and pry then one by one slowly

[@federicocerbonim7654]

hope he disconnected the battery.... very dangerous if not...

Is this same for pajero io

I'm not sure, we don't have that in US

push the hoses off with plyers not pull them off , they fall of instead of damaging old rubber!
