I filled up the fuel again today and again I am having the same problem with the fuel gauge. I filled it up to the top and it said I have less than half a full tank.

So what did the hidden OBC Menu show?

What side of the tank level sensor is not reading correctly?

There are 2 level sensors in the tank.

thanks for your advice?


i have had several cars with problem areas. my 135i and 335i had the HPFP and Injector issues. rather that replace injectors and fuel pumps (before the recall came out), i just monitored my car's performance. i could tell when the fuel pump was beginning to go out. i replaced it then.

i plan on doing the same thing with my e46. yea, it's a completely different issue (HPFP in N54 versus the e46 fuel pump). i honestly think the warmer the climate, the more reliable an e46 can be.

the CCV issues can be blamed on cooler weather. the fuel pump could possibly be traced to cooler weather, as illustrated in this thread by JFOJ.


i'm just providing perspective to members that may feel paranoid about their car failing all of a sudden. most of the time, there are subtle symptoms you can clue into regarding a failing fuel pump. or cooling system. or CCV. far before the catastrophic failures you hear about.


i'm not new to cars lol. i've had about 16 different makes/models.


if my posts make you uncomfortable, or you think i should keep my decision/opinion to myself, simply put me on your ignore list

There are 2 level sensors in the tank.
Its hard to tell which is incorrect. They both get a reading for example, I bought 60 litres and the reading was like 240160 indicating around 40 litres.

When driving today the fuel gauge went up slightly and now its 3 quarter full. Yesterday it only said it was half full.

Is it possible to position the fuel pump wrong where the level touches the wall of the tank and gets an incorrect reading?

You sure the connector is engaged properly? If you have both a fuel pump problem and a fuel gauge problem, it's worth checking. Wires for both run through the same connector. Floating ground could cause some weird stuff.

You filled up the tank to the top despite the fact that you knew there was a good possibility that you would have to pull the pump out again to examine it?

Have you put in a new filter lately?

325CI 2001 Fuel Pump

Guys

Can you assist, I require a Fuel Pump 325CI 2001

I've already purchased x2 from Europarts & Dingbro, they both stated the part was correct fit. However when the parts arrived neither fitted (x1 was wrong dimension, too slim & x1 had L-Shaped fuel inlet)

The product I require must have the stand up fuel inlet (not L- Shaped) and must be correct dimension.

diameter = 5cm
length = 13cm (including the fuel inlet)

Georgeca,

Sorry I cannot offer much input as here in the US we typically purchase the entire pump & fuel level sender all as a single assembled unit for about $130 US.

This is a good price for a pump as typically a raw pump is close to $100 and there is not guarantee it will fit properly and it will have a good pickup strainer.

So it looks like your parts stores are selling just the raw pump and it will be difficult to install without a bit of playing games.

SolidJake,

Did your pump finally fail? or are you just going down the PM road?

I saw you posted on the first page of this thread and at least you were thinking about a pump?

I like the email idea, that you get a reminder e-mailed just days before you are left stranded!!

I need to determine when I want to change the fuel pump in my GMC Yukon, as it will not last forever either!

^ Look at post 340


I have it but I've been working midnights all work with no time to do anything. I will try to do it on Monday including my EMP water pump, tensioner and idler.

Oh and yea, it's PM but I know it's failing one way or another. I had over a 1/2 tank one drive, turned off the car and it was under 1/2. Turned it on again and back over 1/2...

Sounds like someone stole gas from your tank, felt bad about it and added too much back.

Good to see you got your pump replaced. Bet it feels great! Keep old pump and give to a local NYC fanatic who doesn't have funds.

SJ,

I noticed you had the drivers side sender as well.

I have 2 senders for my E39 M5 I need to install at some point when I have time as well.

Hope you gain some performance with your new pump. Will be interested to see if you can tell a difference.

I'll definitely do a write-up of anything that I notice. My fuel filter was replaced 30k miles ago.

Hi jfoj, I think your post may help me solve a problem with my 2002 318i (88 000 kilometres, 2litre 4 cylinder petrol, automatic). The car starts fine from cold but idles very rough once on operating temperature with the rev's hunting between 700 and 1000 rpm. It is also sluggish when accelerating from standstill. We've checked the vacuum hoses (as you suggested elsewhere) and checked a number of other components. There are no codes. An odd coincidence (???) is that the fuel light comes on with more than a quarter tank left. This - in light of your post - makes me think that I have a fuel pump problem with total failure imminent. I would appreciate your opinion on this. If I read your post correctly you suggest I should replace the fuel pump and filter anyway. Is it a job I can do at home?

Suggest you see my link below for the Hidden OBC Menu. This way you can monitor the fuel level in each half of the fuel tank. The left side of the tank should be empty by the time the fuel gauge reaches about 1/3-1/4 on the fuel gauge.

I cannot say for 100% that your pump is causing your driveability issues, but it is very likely it could.

As far as this being a DIY, very much so. Just make sure you change the pump when the fuel tank is less than 1/2 full and use proper judgement regarding safety around fuel.

Here in the US we purchase the pump and sender together, it makes the job so much easier and faster. Not sure what this part may cost you down under, but here in the US we can get the pump/sender unit for about $125 US.
