Hmm, I thought of that idea myself (using a bicycle pump to remove the
problem of sealing the tube while you take a breath), the technique of
using an air pump to pressurise the tanks to get fuel out is used in
the vintage racing cars that I go and ogle at on a regular basis so
it's a familiar technique.

The practicalities and risks to weak piping meant that I dismissed it
in favour of just getting a long pipe, dipping it all the way into the
tank, sucking until the fuel was near the end then plugging it with my
finger. Then I'll take the other end of the pipe out of the garage
door, down the steps to the jerry cans as that's the only way I'll be
able to get the jerry cans low enough to siphon with any real speed
and reliability. I can't raise the car up much but have a handy
2-foot drop from the garage to the patio that I think I'll use to ease
the siphoning process!

If that doesn't work then I'll try using the fuel vapour vent hoses
attached to the filler necks that run to the charcoal cannister to
pressurise the tanks then see if I can get fuel to come out of the
fuel pump return connection. From the parts diagrams, this appears to
be an open pipe that terminates just above the fuel pump inlet filter,
so is in an ideal place for siphoning, being actually in the recess at
the bottom of the tank that contains the pump inlet.

I only just got access to the tanks themselves this weekend, sorting
this out is scheduled for a few week's time. I'll let yer all know if
I get incinerated or not!!

thing is, it only takes quite a low pressure to make the petrol climb up the
pipe. If you get enough pressure to rupture things, you've probably gone
OTT.

besides, doing the thing with the rag in the filler inlet won't make much of
a seal anyway, and any serious pressure will blow it out again. If you go
with the "by mouth" technique, you'll not archived more than a few psi
anyway, unless you have abnormal chest muscle development.

I now have the following procedure to get this job done. It's of only
mild interest to landy owners probably.

Once the fuel system is depressurised (e.g. if you have no engine) you
can bung a clear hose to a jerry can on the return line (the one with
the long pipe with the twirl in), and a bicycle pump on the fuel inlet
filler vent hose that normally runs to the charcoal cannister.

Then pump like mad, keeping an eye on the clear hose for signs of
petrol coming out, of which you will see none. Notice the hissing
sound as air escapes from the many leaks in the fuel system, and dash
around like mad trying to patch them.

Give up on the bicycle pump and start blowing like fury into the
filler vent hose until you go light-headed and stumble around in the
engine bay, while trying in vain to spot signs of fuel beginning to
travel down the clear plastic hose. Curse and swear at Lotus for
using cheap plastic clips on the fuel vapour cross-over pipe which is
where the leaks are coming from, and try in vain to find some suitable
jubilee clips to replace them.

Fail to find any and start blowing into the vent hose again even
harder, this time mostly for entertainment, and resolve to buy some
proper sized jubilee clips on Monday.

Notice that the 20-litre jerry can is now overflowing with fuel, and
remember that fuel is transparent, and once it's flowing you won't
spot it in a clear plastic hose. Realise that you got it right on the
first go, swap cans, and console yourself with more blowing into the
vent hose and stumbling around in the engine bay.

Try to figure out the best way to tell how full a solid jerry can is
of transparent liquid, and after many failed attempts at an accurate
means, figure out that blowing into another hose while lowering it
into the can until it makes farting sounds is the best method.

This has been a public service announcement on the behalf of the
barbeecee.
