Metal Flakes!!

While taking a look at my fuel bowl this weekend, I noticed when I took the cover to the FF off, in the minor amount of fuel that was sitting on the top of the FF, I saw some mettalic flakes! Fuel Pump problem? I spoke to another local tech, and he said that running a little ATF in your fuel will help the lower lubricity of the newer fuel. I am assuming that these flakes had to have come somewhere from the fuel system. Anyone have any ideas on where I need to start. Let me add also, that the flakes were only visible when you looked at the fuel a certain way, (like a hologram yunno). Any help would be appreciatted.

Don't worry...

Don't worry, the flakes are a normal occurence. They appear after a while. Not a problem as long as you drain the fuel bowl before changing the filter so the flakes don't get caught in the return line pressure regulator or in the feed to the injectors.

dont put ATF in your fuel. If anything run 2-stroke oil. 2-stroke oil is meant to be burnt and I run it in most of my tanks, it helps with injector noise a bit and its a nice piece of mind for extra lubricity. ATF is not designed to be burnt in a engine (or at all for that matter) so I would stay clear of ATF in the fuel.

I have ran as little as 1/2oz. per gallon to a max of 1oz. per gallon. I get the oil at Walmart, its basically a gallon of ashless 2-stroke oil it comes in a green or blue gallon container and its pretty cheap. I found a nice funnel that also doubles as a measuring cup so I can measure the oil I put in the tank. Its kind of a pain in the butt to do at the pump (all the measuring and pouring of oil and stuff) but if you have the time to do it its worth it I think. I don't do it every tank, but if time aloows for it I will add the oil.

i wouldnt run two stroke oil.

Two stroke oil is designed to mix with gasoline...which is a solvent based fuel....

Diesel fuel (with the exception of bio) is NOT a solvent based fuel. Mixing two oils of different weights is all you would be doing......and those oils will tend to seperate and it wont be efficient all of the time....meaning it wont always be mixed.....

commercial grade fuel treatments are made to blend with the fuel.... but thats just my two cents..

well what you say makes sence I guess. If the two are meerly 2 oils of different weights and will basically separate then maybe its not worth doing, but I can honestly say that I have noticed a physical sound difference in my truck when I do run it. The truck tends to sound smoother or softer at idle (hard to imagine, I know). I have been running the white bottle PS so my fuel wont gel up on me cuz its been COLD here lately.
