There was none.

Although I wouldn't think it to be great, a couple of stutters could be acceptable. If it happend with a message in the display that said CRITICALLY LOW FUEL, one would think people got the message. But to continue to run crippled - why on earth? And what could possibly be the point of making he car ignore any fuel added?

It's a system made for daft, ignorant people that doesn't pay attention or know exactly what they are doing. You may say I'm stupid for running the car low, but surprisingly I've managed just fine for over 30 years without any car ever telling me anything other than that what comes from the fuel gauge and trip meter. Since I only got 45 litres into the tank, it mean the car was still good for more than 70 miles. Electronic gadgets I do not need prevented me from driving them, or even a couple of them.

You have two options; letting fuel pick-up drop with the fuel level or leave it at the bottom of the tank. The latter is the only system I have seen because the other options will stand a huge risk of sucking air. The placement of the fuel pump is irrelevant.

More Intelligent posts by me !!!!

schematic drawing from VADIS of the V50 Fuel tank & Pump arrangement ....

Please Note Location of Item 27 (FUEL PUMP) it is at the top of the tank ALSO note Fuel Sender unit (Item 27A) ALSO at the top of the tank ..

Pay particular attention to the SHAPE of Said Tank ... you will note that the "Transmission Tunnel" runs "Thru" the middle of it..... with the sender unit on one side & the Fuel pump on the other ......I would think this is a BAD DESIGN as you MAY get a situation where you COULD have MORE FUEL on the "Sender" side of the Tank than the "Pump" side ect ect ...

EDIT**** On closer examination it would appear that there is ALSO a Sender unit attached to the fuel pump .... VERY intriguing WHY TWO "SENDER UNITS" ??????????

As I mentioned, fuel pump placement is irrelevant. Fuel level sensor is virtually always fitted from the pump. Motorcycles traditionally used fuel tanks with a tunnel, only more pronounced, and usually fuel outlet on just one side, but some had them on both sides to allow every drop to be extracted.

In the Volvo tank displaye, you will either find fuel pickups at the lowest point* in both halves or there is some sort of internal connection between the two.

The car understood that fuel had been added, why else would it stop showing distance left to empty? It just couldn't figure out just how much and played it "safe" by saying it had no idea whatsoever, yet retained it's original mileage to empty as a cut-off point.

Splash while driving should quickly move fuel between the two halves even if there wasn't an internal system to ensure that the level always stayed even.

*Usually, not entirely lowest, but usually a small "bucket" that will hold fuel even when level is low to prevent air to be sucked when cornering with a small load. Also, the actual pickup will be sitting a little above the lowest point to prevent sucking up just the dirt you talked about earlier.

This has also become more noticable as the price of fuel has gone up.

Theres nothing worse than putting £10 fuel in when the needle is in the Red, turning the key only to find NO change on the fuel gauage.

First time my 2.0d did this I thought the diesel pump had screwed me over and was about to have argument with the petrol station staff!

With the price of fuel at the moment, £5 does not register AT ALL. Even if you leave it overnight. Crazy.

Exactly my point!

Is it just me or is this one of the most pointless threads on the forum??

Someone is daft enough to let their car get so low on fuel and then complains that the car doesn't drive normally!

What next? Someone complaing that they almost died of thirst because they didn't drink anything and then blaming the water company?????

I have been called pedantic and a boring old fart but personally,I always start looking to put more petrol in once my tank hits a 1/4 full.I am not well off,I have just got into the habit of never letting my tank run low.I have done this on every car and motorbike I have ever had and in doing have never had fuelling problems or have I been lucky?. I just refuse to believe any manufacturers petrol gauge to measure what's left in the tank.

Only it wasn't low on fuel, the car imagined it was low on fuel. There is a difference. A significant one.
