We had 2001s they had the big filler with the FPR attached at the end (but they did come apart) i still have the FPR from wife's when i replaced. I was thinking of cutting it in half to determine exactly how it works and how it might be possible to malfunction In a way that would send extra gas. Theoretically something could go wrong with the spring/diaphragm that makes it take more pressure to open. Could restriction on the output to the left tank cause this?
