Had mine for 4 years and it works well. Removed it from my old truck and installed in the new one 3 years ago. The install is not hard, putting the valve into the trucks fuel fill hose maybe the toughest part but even that was not bad.
One thing to bear in mine is they do not hold as much fuel as advertised. Mine is a 37 gal. tank and I never got more than 33 gals. in it ,and most often get 31 or 32 gals. in.
