Hello All, All this talk about fuels and fires lead me to the Chevron website were I discovered this note about Reformulated Gasolines, which are used in many major cities to curb air pollution. Those of use with rubber fuel lines ought take note: From http://www.chevron.com/prodserv/gas_qanda/reform.html "The rubber that is used in fuel system parts, such as seals and hoses, may shrink, swell, or lose strength when exposed to RFG. This reaction could cause fuel system leaks in a very small percentage of vehicles. Because RFG differs only slightly from the gasoline that you have used in the past, auto manufacturers do not expect RFG to cause fuel system leaks in the majority of vehicles, particularly newer vehicles. However, if your vehicle is older (more than 10 years old) or has high mileage (more than 100,000 miles), you may be at greater risk of developing a fuel leak. Because fuel leaks can cause vehicle fires, Chevron recommends that you consult a qualified auto repair technician to discuss whether your fuel system parts should be checked for repair or replacement. If you suspect a form of leakage, which can often be detected by smelling gasoline at times other than when fueling, consult a qualified auto repair technician immediately. Do not drive a vehicle with a fuel system leak." Darrell Johnson '90 Vanagon Carat Mission Viejo, CA
