He'll need a lot of amps though for a pump.

And when the fuel is cold or there's a big lift it will be a lot more.

Make sure the neg output lead is bonded to mains earth via the PSU's mains lead. Some of them float so a fault could put 240 leakage on the output.

10A and 25A units are common

Class II supplies are generally safer than class I, but if you're pumping fuel, earthing it would eliminate those tiny sparks.

Yes - not given for the actual pump when I replied. I was thinking of a small pump like you'd use to empty the car sump. Wonder if a decent PC power supply would do it? Some older ones produce a lot of amps at 12v for HDs, etc. And can be very cheap used.

Er. He put a link to the pump details in the very first post!

Don't do links. Surely not too difficult to post its details in text here?

You must miss an awful lot of details, then! What about when people post links to photographs? They're often vital for understanding what is being discussed.

I think I would make a little stand for the barrel, big enough for a 20 litre container to sit underneath and between the legs. Add a tap to the barrel and a bit of hose, no other tech required!

If you're not doing it that often I'd suppport the idea of a small hand pump. For instance they one in the link below, but they do many other models, some specifically for your task, this just happens to be that one that I got for our wetroom sump pump backup (as the top of the sump is higher than our room floor, and could potentially get flooded from outside).
