I WANT to convert my 2004 Ford Explorer to gas and I would like to know which is the best system for it.
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.
