Fuel scavanging sound from fuel tank

Ive noticed when my tank is just below half full (on the 'accurate' dash gage :) there is a scavenging sound coming from the fuel tank, sounds like the in tank sender unit is struggling to 'pump' fuel. must admit im unclear if it is actually a pump or just a level sensor. Im wondering if something ...

Hi GripGreg, its a really good point, I do hate doing anything like that just on one side, will consider that when I get to the root cause of the problem, safety first right.

Thanks

Thanks Jody,

Thats kind of scary, I do have # 1, 5 and 10 from the major components, but there was no sign of 2, 3, 9, 12, 13, and 14. I guess im carrying less weight around :)

Im noticing that 2 and 3 will put a gap between the top of the top spring support and the underside of the strut top (5 ...

Thanks everyone for your help, appreciate it.

Will go get myself some pipe wrenches,

Mike, sounds like you have obviously done this many times, I was actually wondering if I have something missing, always a possibility if someone else has had a go at it before, when I removed the big top nut, I ...

Just used a ball joint splitter to drop the tie rod off, and took off the sway bar link to see if I could isolate the strut more to make sure it is that, still knocking. Almost sounds and looks like the piston is not sliding in and out of the shock evenly at a specific point, imagine if you took out ...

So I finally got hold of a replacement used top mount, to cut a long story short, got it fitted yesterday, took me about 3 hours in total, and it knocks exactly the same. The old strut top looked ok actually, put the new one on anyway (I have to say it is used, but looks pretty new. While I had the ...

Ok so my local BMW dismantler knew what I needed as soon as I talked to him, he has what he thinks are good ones on an e21 (pretty sure he said e21 and not e23), says they are the same. He should be able to get one for me by Monday.
I bought a 1" 1/16" deep socket (couldn't get 27mm) to get the top ...

Ok so got someone to stand on the strut tower, holding on to the open hood they were able to bounce the car pretty hard, knock every bounce, loud. Had a feel around underneath, bottom ball joints, sway bar, track rod ends, cant feel a thing, really does sound to be on the top mount. If I place a ...

Thnaks guys, usefull to know. I have spring compressors so think I will whip the strut out and have a look, when you say its easy to see if it looks broken or not, will I see the rubber all falling apart, splitting etc. I know the top mounts have some give, they are a damper of sorts right, not sure ...
