I am convinced of the need for an additional fuel filter on the Duramax, but why have I (we?) not heard so much about fuel filtration on a gasoline engine? Or is it just me?

<LI>Is injection maint cheaper on a gas engine?
<LI>Injectors for Diesels are less tolerant to contaminations?</LI>[/list]


Just curious if I should be looking for something on my '03 Yukon XL. It has a 5.3L (did I mention gutless?) http://www.dieselplace.com/forum/smileys/Cry.gif in it and gets MANY more miles on it than my Duramax will see. It is the family "mini-van" and gets just over 2000miles/month. http://www.dieselplace.com/forum/smileys/Confused.gif
