Cotswold EB Pump

Good morning all,
The pump on my 2011 Cotswold has packed up. It is silent when taps are open and is blowing the fuse.
I have read that if the submersible pump has died the best option may be to replace with a more accessible Shurflo pump.  Has anyone done this?  Can the new pump be fitted in the van without dropping the tank to access the Whale?
I am hoping to sort this before going away for a week next weekend.  Any advice would be most welcome.  Thanks in advance!

I believe you are able to leave the submersible pump in the water tank.

However when I updated mine to a Shurflo pump the dealer removed my old submersible pump, as he had to drop the tank as the water sensors were to be replaced under a warranty claim.

Having just replaced my float valve in my fresh water tank myself on my Burford due to time/distance to the dealer, it is a very simple task to drop the tank if it's a similar layout to mine. I had a Cotswold before but can't remember if I ever looked. Doesn't need any speciaist tools, you just need to be able to get under the van. 
I'd have a look to see if it's hung on two bolted straps, locate the wiring and unclip it from the chassis, then drop it without removing the sensor connections. There should be enough cable length without any disconnections. Mine has a separate water fill as well as the whale, but the Cotswold doesn't so it should be easier.
I used a trolley jack to lift the tank back in position to re-strap it, but there's no weight in it when it's empty. Once it's dropped removing the float valve or pump is easy and I got a replacement from Amazon the next day.
Good luck, it's not difficult.
I have a camp room from my old Cotswold taking up space in my loft if you are interested?

Heres a how-to from the Factsheet section.?.

Thanks everyone for your contributions.  I have a guy who's far more technical than I, booked this week.  Hope all goes to plan.
