: I own a '99 jeep wrangler sahara edition that has been pretty much problem free from the date of purchase. recently though whenever I gas up it keeps on kicking back the pump as if it were full- I've been told that this is a "vapor lock" problem- is this correct and what can I do to fix it?
Mine does the same thing sometimes. It's got to do with the tight bends between the fill neck and the tank plus with self-service they have adjusted the pump sensors real sensitive. I tried for five minutes to put gas in my Jeep one place and only got a little over a gallon in. At another station, it filled until it spilled gas out onto the ground.
Try a different pump or a different station.
I've replaced so many parts that my old Jeep has become my new Jeep.
