Yes - I totally Understand - I use a fuel additive @ every fill up just for that same (Safe/Warm Fuzzy Feeling) - but I also know how horrid the quality of the diesel in the states is & adding a high quality diesel fuel additive can do nothing but some what benefit the entire fuel system in some areas - Be it Lubricity / Cleaning / Demulsification.
I was only attempting to make a simple minded point that - Nothing will benefit this pump to help with service life - except a possible golden 4 leaf clover!
My comment was not directed @ your statement - I should have stated that in my post.
