tank pick-up; how to get that last gallon?
Today's brain bender.
I removed the petrol tank in order to fix the sender - got it working after cleaning it up - whooopee!! 
I've measured the tank and it holds 35.0 l (7.8 gallons) but I notice that the pick up tube has been welded 50 mm from the bottom. A quick
calculation shows that the last gallon will never be used up thus the capacity is 6.8 gallons.
Anyone with half a brain would have put the pick up lower or else have it curve down towards the base ideally with a little mesh filter on the end.
I am trying to figure out a way to reclaim as much as possible of the last gallon.
There is access through the filler (diameter 47 mm) and through the sender (50 mm diameter). The hole for the sender is in the side panel above
the pick-up tube and the filler is in the top.
I am trying to avoid anything that involves welding for safety reasons so fishing for ideas how to get the pick-up tube to reach lower down.
Some ideas I have had are:
1. push on some hose and weigh down the other end so it rests on the bottom but how to get it onto the 8 mm tube inside the tank?
2. put wire through the pick-up tube to pull on a weighted hose.
3. drill out the pick up tube and fit a compression fitting but it would be extremely difficult to get the nut on the fitting inside the tank.
Other ideas welcome (and is it worth the bother for 1 gallon? Having the pick up high means any crud and water in the tank will not get sucked up so
it is not all bad).

Hi, what about fitting flex tube inside the pick-up tube? Push it down through pickup and let it rest nearer the bottom.
What size is the pickup tube?

That Gap is so you dont suck up all the crap in the bottom of the tank.
Remember that Land Rovers go to all parts of the world, where the fuel can range from Crap to one step beyond parafin
You should have a soldered on wire gauze sock on the bottom of your dip pipe.
Mine like most had broken.
So get down to you local Land Rover dealer, and look at a 90 /110 parts manual (NOT a series parts manual), they have a nice little plastic filter
that pops on the bottom of the pipe.
Try LR part no PRC2475
Trouble is you cant put it on the pipe and through the hole in the tank as its too big.
So.....
bend Up the end of a wire coat hanger so it makes a loop at 90 degrees to the main bit of wire. Fit the filter into the loop. Feed this through the
Tank Fuel Sender hole (Much bigger hole).
Then fiddle the dip pie through its hole, and slip the filter onto the pipe end. Push the lot to the bottom of the tank to slide the filter up the
dip pipe. KEEP the Coathanger bracket still round the filter as you dont want it to drop off the pipe. When its firmly on the pipe. Pull the pipe back
up a bit and slip the coathanger off the filter. Then just bolt up and fit the dip pie and sender unit.
It sounds more difficult than it is to actually do.
Prefit the filter to the pipe so you can get a tight fit without being too tight BEFORE you try to do it in the tank...
You dont want to loose the filter in the tank.. or its a Tank out job.
Guess how I know that?? 
Filter is about £3 ish..last time I bought one.
Have Fun... It may have bent your Brain... but I have done this one three times now!..

this ain;t for the LR - but now you mentioned it, I made my own brass gauze cone to fit onto the pick up tube as the pone I had perished; not that
hard to solder one.
The tube is 8 mm OD, about 6 mm ID; putting a tube into it will make ID smaller and I am worried about restriting flow.
So far using bits of wire I have hooked on a curved tube on the inside; not sure if it is not hard enough though.
Mulling over an idea using a bolt and splayed wedge arrangent at the mo'
