396chevy Posted April 22, 2009 Share Posted April 22, 2009 Hello and i recently bought a 2000 lexus ls400 with 180k and every time i fill up my gas tank it overflows, i mean it clicks off then 1/2 sec later fuel comes spilling out? Whats going on? someone told me it is the auto shutoff valve in the filler neck but i can find any info on that? please help. thanks in advance Quote Link to comment Share on other sites More sharing options...
nc211 Posted April 23, 2009 Share Posted April 23, 2009 I think there is some sort of pressure cannister in the area of the filler neck that is probably ready to be replaced. I think, I can't quite recall. Or maybe you're sticking the fuel pump too far down the neck of the filler? You're not trying to "top it off" are you? Because it'll definetely kick-back on you then, every time. I think it's a "toyota" thing in general, as our 4runner will do the same thing if I try to "top" it off.
