That's exactly what I intend to do.
My previous post was simply to highlight a problem that those who have 'T'd into the return pipe may encounter.
No-one appeared to know how far the return pipe went into the tank. My post showed this didn't matter, (in my case), as there is a non-return valve preventing fuel being drawn from the tank via the return pipe.
I have ordered a pick up tube, and will fit it when it arrives.
I dropped the tank, with a view to extending the return pipe further down into the tank, to solve my issues. I had seen images of the sender online, and had purchased/collected several different diameters fuel tubes, ready to extend it. It was a surprise to find the 'built in' non-return' valve, so I hadn't already got a pick up tube.
