People with fuel injection systems that use the term "Vapor Lock" may have fuel delivery problems, they are just using the wrong terminology. Kind of like saying "Indigestion" to describe a heart attack! The Bosch K-Jet system is VERY reliable with just a couple of caveats. It has a low tolerance for dirt and it MUST be set up correctly by someone who knows what they are doing. It is not really any more "complicated" than a carbureated system, just different. Dual-diaphragm pumps did not *cure* all of the ills of carbureated systems. Some cars (not Deloreans) suffer chronic vapor lock. Especially on hot days and especially with the new blends of gas. Yesterday Lukeoil got fresh deliveries in my area and cars were dying all over the place. Seems the latest blend from Lukeoil is 50% water!!!! All of the Lukeoil stations on the main highways got the stuff! There were cars all over the sides of the highways and stuck in the stations!!!
