Looks like a station I use is pumping brown slime into my tank when I fill up. :suicide: I have been using Killem and some PowerService cleaner along with #2 since I replaced the tank. Well I have the tank out today with brown stuff plugging the sock again. Good thing I left the sock off the Burb. Looks like I don't have a choice but to add a good prefilter before the pump. The China knock off socks do not have a bypass. I recommend an external filter and no in tank sock. It is no fun to drop the tank for a Fing sock!

I have been loosing top end power past few months and yesterday it was starving for fuel and nearly stalling.

At least this clears the Biodiesel I like to use as the source of the problem.

Fuel filter was black and surprised me as I didn't think it was in there very long or had checked it lately - I wrote it off as being confused with the other 6.5. Now I don't know. But The FFM was nasty when I replaced it last week.
 
Do you use exclusively pump ULSD?

Brown slime? Is this some form of algae?

Livin' good in the neighborhood, eh? Yummy brown slime.
 
Have you or are you going to say anything to the station? I wonder what they do or not do for bulk tank maintenance? Let us know. I tried to inquire what a Pilot station did once and the cashier / assistant manager (long time employee I had seen for a couple years) didn't know. I think the maintenance crews for the pumps or the distributor handled it ????

Not sure if Pilot is a national chain but they have several large Truck Stops around here and have thier own tanker trucks.

I understand their are something like 4 regional refineries but now sure how many layers of distribution there are. I have only seen a few large tank farms but several tanker truck smaller oil companies.
 
It is from a large truck stop I always use or a Fry's grocery discounted fuel station.
 
When you figure out where the culprit is, let us know cause with my luck, I'll hit it when I come through town.
 
Did you have any indication of bad fuel at the pump ie slow nozzle or bad smell or anything else?

Could have been truck stop. Especially if tanks were getting low or recent fill up while tanks were low to stir up sediment. Does either station have a visible filter?

I don't know if a filter will seperate slime or algae/bacteria or what ever grows in fuel/water mix? I guess depends on micron rating.
 
Only the tank sock was bad. The Fuel pump screen had some brown stuff on the bottom but not plugging the screen. Walbro fuel pumps are near indestructible, but, I rebuilt both of mine over this mess.

Here is the new China knock off garbage tank sock bottom left, note missing bypass valve. That little amount of plugging is enough to starve the truck to a near stall. The top is the Suburban tank sock. To the right is a Walbro screen removed from the suburban AFTER the tank was replaced. Figure it was trash in the fuel line. Yeah the Suburban tank was unbelievable it was so bad.

Posted before: This is what your fuel filter looks like when you are in deep trouble.

Glad to hear that it was not as bad as last time for you. But looking at that old photo again, YIKES! That stuff is ugly.
