R1150GS: Using the fuel pump to empty the tank: Lost thread

[DrAlf]

Just been searching here and ADVrider for the past hour or so. I remember seeing a thread about using the fuel pump to drain the fuel tank using quick disconnects and a length of fuel pipe. Can anyone point me in the right direction of the thread? Looking to drain the tank and swap internals tomorrow afternoon – tank if full of fuel

Thanks

Looking for it myself and found it here:

For some reason these decades old links don't seem to be working any more. Is this info still around in a simple form?

Something wrong with a length of hose and a jerry can ?

If you're scared of a gob full of petrol (fair enough), you can buy a syphon hose for about £4 on ebay etc.,

I have a dedicated siphon kit sold by Aerostich here in the states, but the baffles in the tank prevent the autosiphon lead from reaching any fluid. I disconnected the fuel lines (hooking up the bike side of the quick disconnect to a longer excess section of line) and cranked the starter until the battery died, but nothing came out of the line.

I am trying to remove some petrol that is almost 2 years old. I wasn't sure if bad fuel could cause problems with the fuel pump, but that is what I was advised to try at ADVRider. I don't think even with a more robust battery this approach would work to empty ~12 litres of petrol, but further explanation of the situation seems to have become some sort of classified subject matter...

Just don’t light a fag too soon afterwards and you’ll be fine.

If you have a spare quick disconnect, just disconnect the return line, connect the other half of the quick disconnect attached to a decent length of tube and let it low by gravity.

Does the fuel pump mechanism leave a channel open when it is not running such that it will maintain a syphon?

 

[ThreeDawg]

If the engine can be run you can wmpty most of the fuel out of the tank by connecting a hose to the fuel pump return line and running the engine. I use a length of hose and a spare connector.

Seems the most common reason to drain the tank would be if it had bad fuel prohibiting the engine from running.

Would one be able to swap the tank off a 1150GSA onto a 1150GS to help troubleshoot, simply leaving the crossover disconnected?

Of course, you can swap tanks either way.
But using an Adventure tank you need to connect the under tank cross over link from the left to the right ear.
Otherwise you leave yourself open to leaks from the connectors , so really for safety reasons
and left side would not be drained . Fuel pump sits on the right side.
If you mean for a short period as a diagnostic way you certainly can keep the under tank connection off, provided there is enough
fuel on the right side…
And another reason to drain a tank is if you got a full tank and need to remove it then 32 l is pretty heavy stuff to take off….
