The effiencies of a modern fuel injected engine demand high quality, with detergents, fuel.
Out of interest, are you aware of the Top Tier designation for fuel providers?
Anything else, good luck.

 

@guy How sad it is it that our gasoline has gotten so bad we have mark pumps with a top tier designation, we have that in Canada now too just say it yesterday at a Chevron station.

 

Ok, about to drop my tank... but I am unclear what I need...
Does anyone have an updated parts list... by what I understand, originally they came from factory with assemblies, then later the filter, flange and lock ring were all sold as separate pieces... is this correct?
