Thanks for all of your comments

Not sure about getting towed by another 4x4, as it's a 13 hour drive at speed limit as it is, much longer at whatever the lower towing speed is here from Italy and through France to get back to Kent. To top it off, I now have a broken wrist from a snowboarding accident! So would be a bit tough on me to do the tow combo. True the costs of my dad coming all the way out here will stack, and yes have come across the problem of international hire - Seymour Hire for example have a 4x4 + trailer, but not covered abroad. Will keep searching though thanks for the recommendations.
I had euro cover when I came out to Italy in Dec, but when my policy renewed in Jan little to my knowledge my euro cover didn't as my car was then more than 10 years old and they don't cover cars more than 10 years old. I argued this out with them as wasn't told but they just said there is nothing they can do now anyway as the car is too old. And unfortunately I only found this out after I called after it had broken down. And their recovery company Call Assist wanted to charge £2500 to repatriate me home! I just assumed non-member AA or RAC would be about the same?
Will look into those transporter companies thanks everyone - I was told of a company called Eclipse just yesterday, they're based in Canterbury so have sent them an email.
Also been on the case trying to find a second hand pump with help and advice from other members on here, as well as Vauxhall Canterbury helping, but not found a second hand one. But through Mark's advice have found a company who can send a new one (BBA Reman) but at a cost of £1600 + vat and shipping though. Also Diesel Bob is waiting to hear back from Bosch to help me, but potentially at a lower cost. Update after the easter weekend though...
Really appreciate everyone's input
