Last week I cleaned my FPR screen and took a peak inside the fuel bowl. I've noticed the fuel was a bluish color, but the more I read on this forum I hear its a bad thing. I change the fuel filter every other oil change and only run Hess diesel, which I know they move alot of by me.





I also got alot of crud in the bottom of the fuel bowl. There are more pics in the link in my sig.

 

I've got that same stuff, but less than you. I buy my fuel from pilot. This stuff is kinda like flakes of white stuff.

 

i'd flush that out, and buy some good shell or BP fuel!

 

I've already flushed out the bottom of the housing, but after 10k miles its still there. Its flakes suspended in the fuel than settles out and forms a mass on the bottem of the filter housing. Pilot is a travel center off I80 and I77 here in ohio that must serve atleast 100 semis a day. Dont the fuel tanks have some kind of coating inside of them?

 

edit: double post

 

the filter looks too clean? that looks like an algae bloom but you should have more slimy sludge inthere. odd coloration,i would add algae treatment and some water seperator

 

2'nd pic looks like water in fuel. Drained mine a couple weeks ago in containter and sat outside then rained a bit, not much but looks the same.

 

yeah, i agree with the second pic but it looks like its pretty calm in there. i would say catch some in a clear pan and let it sit for an hour or 2 and see if the water droplets will form.

 

Are you using any fuel additives .. if so and what brand and amout ? Not an expert in this area but just maybe as I think major diesel dealers might add winter blends.

 

Second question .. is your "Water In Fuel' sensor still connected. Seems like this winter almost every time I fill up I get at least 1 "Water In Fuel" light and just drain about 5 seconds the the rest of tank is OK. Go figure !!!!

 

yeah that day i completely drained and flushed it with the with bottle power service (all that I had on hand) tomorrow i'm gonna look in there and see how it looks. if its still like that i'm gonna drain it into a clear container like you guys suggested. (if i can find where the spout is so it does not spill all over my IFS)

84-250- thats exactly what my mess looks like, flaky stuff floating around in the fuel and then settles at the bottom.

Hussler- i did notice the 'water in fuel' light flashing before I flushed it and i dont recall seeing it since.

2 stroke- hess is pretty much the best around here, dont have a BP or a shell nearby

joe- did the algae stuff you used ever work? and what was it called? maybe i got algea in its early stages :/

 

Hard to see but first pict looks like air in fuel. Looks to be making its way to the top.
The little flakes you see are they sort of a grey/silver?
The flakes can come from the pump or tank delamination.

the silvergray flakes look to me like what happened when i put diesel fuel in a galvanized can, the galvanizing started flaking off the inside of the can, the fuel had the same flakes and when i pulled the fuel filter it was full of them. that was on a john deere tractor, maybe a contamination from where you get fuel or the inside of your fuel tank.

True also possible.
Galv and #2 dont get along.

sorry i missed that question the first time- I'm running powerservice

my fuel goes right from the pump into my tank i dont use any portable tanks.. hopefully its not from the inside of my tanks. maybe from hess's in ground tanks? next time I fill up I'm gonna try going to a different station and see if it makes a difference. How about the blue color? is that the color diesel is supposed to be?
