Ford Explorer Engine Problems
Ford Explorer pressure regulator
Like you I tried a number of aftermarket outlets here to try to find one, but couldn't, so I would suggest you could hit the Internet and get one out of America. You could try JC Whitney who had them listed in their catalogue when I checked.
Ford Escape air-con economy
The V6 Escape is renowned for its thirst, but a 35 per cent increase in consumption when you run the air con does seem excessive. Have the air-conditioning system checked to make sure it is charged, check the compressor to make sure it is not faulty, and have an air-con specialist check the whole system.
Exploring the options
IT CAN be converted successfully if the converter knows what they're doing. The Australian LPG Warehouse has done several of them using a vapour-injection system and has had no issue with them.
THE best system is the vapour-injection system, which is like the fuel-injection system currently fitted to your Explorer. The other system is a venturi/mixer system, which is like a carburettor if you think in petrol terms. Vapour-injection is more modern technology and has fewer problems, but it is more expensive.
PHONE George Peake at Victorian Autogas (1800 620 945) or Mick Morabito at Eurogas (03 9783 8300). Both should be able to help you. Or you can go to the LPG Australian website for a list of accredited installers: www.lpgautogas.com.au
Lost in the void
THE problem you've experienced with the Explorer is not unknown, but I would have thought the best course of action would have been to repair it rather than replace it. In any case, I would have thought you had a legitimate claim against the insurer and you should pursue it through the small-claims tribunal or other body for problems such as yours. You will need to produce all relevant documentation about previous servicing and the cost of repairs for the engine replacement, and if you can do that, you should be able to prove your case.
