Default Removing fuel from tank

Last day of driving our TDI (before I realized how bad water leak was), I filled it up w/ diesel fuel. Now that it sits in garage and will do so until VW comes thru w/ a date, how do I go about removing at least 15 gallons from the tank?

More to the point... Have you nothing better to do? Even at $3.00 per gallon we're talking $45.00. You'll spend more than that in time and effort recovering those fifteen gallons of fuel.

Punch a hold thru the bottom of the tank, drain the fuel, patch with bubble gum.

You wouldn't take the time to LOOK for a simple water leak, but you're willing to spend your time getting filthy to squeeze your precious fuel from your car?

Someone needs to get their priorities straight...

If I didn't have a pump and hose to put down the filler neck I don't think it would be worth the PITA. There might be an anti-siphon thing in the filler neck too. What are we talking about here, $40 in fuel?

I'd swear that there are people on here that would take the air out of their tire's or drain their rads rather than let VW have it, I can see the nightmare that Canadian's are gonna have with people like that, Have enjoyed our car for 4+ yrs and hate to have to part with it but if VW will pay enough for it we'll buy a new one.

Why don't you then wire me $100.00 bucks so I can get it checked out. Don't expect me to pay you back tho.

If I'm going to have VW take back the car and given the water leak is severe, why then would I want to spend money to find out where it's leaking never to re-coupe the money spent to find the leak? The leak isn't simple BTW as it's bad enough to drain the rez in a couple days. Not my fault VW got their hand caught in the cookie jar. Frankly, I think whoever was able to conger up the scheme is pretty smart. However, we, the owners of such vehicles are caught in the middle. Add to that, VW's known faults of the DEF heaters, water pumps, exhaust gate valves etc.

If removing fuel is simple enough to do, then YES I will do it. No cost to do so other than my time. And yes, I can use it in my diesel tractor.

Remove the back seat cushion. The tank sending unit is on the passenger side under a cover. Just don't damage the sending unit or lines when removing it. You can pump it out with a battery operated pump such as one for filling kerosene heaters or siphon it.

Other way may be jumpering the fuel pump relay and removing the line at the filter but depending on year built the location of the relay is subject to change.

I haven't tried to siphon from the tank inlet on one of these cars yet

There already is a fine collection of fuel pumps on the car.

pull a fuel line from the fuel filter under the hood (use the one that returns to the fuel tank), hook up a similar diameter hose, and start the car. turn the engine off when your collection tank is as full as you like.

That's exactly my point on your water leak. It wouldn't cost you anything to look where it's leaking from. Could be a loose hose clamp or something else that might cost you ZERO to fix, apart from your time.

If you fix your water leak, then you could actually drive your car and burn the fuel you have. Recovering that fuel could be messy, and what would you do with it anyway? Heat with #2 fuel oil? Have another diesel vehicle? Sell it on craigslist? Souvenir?

Removing the sending unit with the tank full of fuel will result in a half dozen gallons of diesel fuel in the floorboard of your car. Not recommended.

O...M...G...all this blather over <$40 worth of diesel, probably getting in excess of $20k from VWoA at buyback.
Rather pathetic, don't you agree??????

Let's just approach this as a mental exercise rather than criticizing the guy for his motives. Knowing how to drain the tank is useful information.
