You Can But A Hand Held Pump From Screw Fix For Around £20.

It still wouldn't get it all out. THE VEHICLE HAS SADDLE BAG TANKS.

Best Thing To Do Is As Above Lubricate It And Use The Pump To Drain As. Tho Still Ring Around A Few Places For A Quote But Not The Dealers.

The main dealer or and independant specialist are the best people to do the job if your vehicle has saddle bag tanks. If you take your vehicle to a garage that doesn't know what they are doing or how to do it correctly it CAN cost you your engine. Would you take the risk of siezing your fuel pump in your engine bay and therefore fooking your engine to save a couple of hundred quid?

A garage that is just after your money will use YOUR fuel pump to empty the tank. An intank fuel pump is over £200 then you have the cost of fitting it. Wouldn't you rather pay the extra £200 in the first place to know it is done properly?

Somewhere in the system there must be a balance pipe between each "saddle bag" otherwise how does the fuel get used evenly from both sides? That would seem to imply that you only need access to the contents of one of the "saddle bags" to be able to empty them both?

That being the case, why can't you syphon the fuel out from the filler pipe ?

The fuel is pumped across by an electric fuel pump under the passenger side rear of the vehicle. Gravity lets the one tank overflow into the other tank to fill it. when the first tank senses a low level the transfer pump transfers the fuel from the one side to the other. If you want a laugh, try and remove and refit the transfer pump. I've done one to enable me to drain a tdv6 without removing the tank and don't intend doing it again. I do anything up to 10 draindowns a week. Sometimes I wont do one for a few weeks. Sometimes I might have 3 or 4 vehicles queueing to be done at the same time. I use the same vacuum evacuation system that the AA vans use. Saddle bag tanks are a nightmare. In most cases the only way to 100% gurantee that ALL fuel is out is to remove the tank. If you wanted to take the risk and use the electric fuel pump to transfer your fuel across then don't forget there will still be fuel left in the system and it may kill the pump doing it.

Just out of curiosity, what do you do with all that 'wrong' fuel?! Do you get first refusal?!

I assume that the, er, plank who has put £80 worth of wrong fuel in their truck is so relieved to have it fixed they don't even think about the stuff that's been removed?!

It has to be disposed of properly. It is put into barrels and then collected by a certified company. I wouldn't put it into my vehicles. It aint worth the risk. Some people do assume we're gonna put it into our own vehicles though. When we show em the number of drums we have full of the stuff they soon realise that we aint using it ourselves. Some workshops with old waste oil heaters use it to heat their workshops though.

SAFE REMOVAL OF PETROL FROM VEHICLES . LAC Number: 57/3

I see. Cheers for answering that one mate. Learn something new every day! Don't think i'm going to start my fuel draining service now after all...

if it's a saddle bag tank as Ratty says I don't think you could pump it out by hand no matter how hard you tried.. the best you could hope for would be to remove 1/2 the petrol... and as much as it is true many people mix a little petrol with their derv 50% is a bit much even if there was a guarantee that it would actually mix...

but if you can afford a tdv8 you shouldn't worry about a few quid to a stealer for draining your tank...

If you are stupid enough to remove the transfer fuel pump and syphon the other side from there you can get all but about a gallon out. I have done it to a range rover once and I won't do it again. It is easier to remove the tank.

You learn by your mistakes.
