Other 70 Problem: Syphoning Fuel from a 2003 Volvo V70 D5

[Macabre]

So my car is shagged and needs scrapping or selling for spares/repairs (cba to fork out and replace the engine - timing belt snapped). It's a 2003 V70 D5 SE.

I only filled the tank a couple of days before so there's about 60+ litres of diesel in it.

I've been trying to google how to do this but I'm still stuck. There's videos of attaching a hose to the fuel feed and blocking the return hose, but I am not 100% sure where these are. Then removing the batteries negative terminal and then sticking a paperclip in the fuse relay to join the requisite terminals (I'm fine with this bit).

Also see one where you can access the fuel tank under the back seat, but I can't get the round locking thing off. The guy in the video used a hammer and chisel to remove it but mines resolutely refusing to budge.

In desperation I just shoved the hose down the fuel cap, and gave it a good suck ) fuel came up, but when I put the hose into the container it started returning back into the tank. Is there some kind of anti syphoning device in the car?

Please help before I just stab a hole in the bottom of the tank (providing I can find it, there's an undertrtay I think) and inadvertantly set myself on fire.

How much hose ? - You probably need 1 metre into the tank and another 1 metre out, preferably lower than the tank to get syphoning going. Or get a small pump you can attache to a drill, or a hand pump/syphon thing

If you’re scrapping it, why not just find the pump supply wires and connect them to an auxiliary battery, connect your hose at a suitable point and run the pump until container is full?

What would the suitable point be? I'm not sure where to connect the hose in the engine bay, or I'd have used the paperclip in the fuse relay trick.

I've got nearly 2 metres I think. I tried the shove 2 bits of pipe in, shove a rag down the hole to create a seal and blow down the pipe but that didn't work. I could hear myself just blowing bubbles. I've probably managed to get a grand total of 200 ml out

I may be wrong here but would it not come out of the fuel filter drain under gravity? As long as the fuel lines are full up to the point of connection at the filter an auto-syphon should be set up to the point the suction side becomes level with or higher than the drain point. However, there's not much room under the car to get a fuel container in.
Another point worthy of note is that unless the in-tank fuel pump is run, you're only going to empty one side side of the saddle tank by syphoning. To get all the fuel out, you'll need to remove the float chamber cover under the NSR rear passenger seat squab and syphon from there as well.
To get the locking ring off the fuel tank the hammer and drift should work (but will likely destroy the ring in the process (no issue if you're scraping the car), but a fuel pump locking ring removal tool will generally work easiest. These can be bought cheaply enough or even made simply (I've heard of them being made from 4" or 6" soil pipe). Some examples of tools here:

If the car is being scrapped anyway, you could tilt the seat bases forward and drill a hole through the floor and into the tank, you'd need to do this both sides to totally drain the tank.

If you opt to remove the fuel pump and sender and get into the tank that way a pair of screwdrivers crossed over and braced against each other can be used to undo the tank sealing rings.

Pity you don't live closer as I need a fuel pump and could drain the tank for you!

Plastic fuel tank,
Just drill a hole in it, have a self tapping screw ready for when you can gets full or you are done.

So in the end I got one of these:

The tubing was ****e, but I just replaced it with what I already had and it worked a charm. Took bloody ages though and I couldn’t get the very last 10-15 litres or so out, but got over 3/4 tank out and now partners car has a full tank so hurrah.
There’s a guy coming to collect it for spares or repairs later otherwise I probably would have gone all stabby stabby on the tank.
