Changed the fuel filter and the ticking is gone so far. The filter was totally nasty black seems to run smoother and have more power so hopefully that's the fix it needed.
thanks for your help guys

 

yea, i gotta change my filter ASAP.

Thanks for the reminder, i have the same ticking noise....

 

Its pretty easy to do just an awkward place to work in, I used the shop rag and compressed air blown into the tank fuel inlet trick used about 10 lbs of air and only had to pump the primer a few times. Started up on the 2nd try .

 

If your filter was that dirty, you might want to change your pre-screen.

 

Black is algae. You need to run some Power Service Silver bottle or other algaecide. You will need to watch your fuel pressure again as the algae dies and ends up in your filter.

If you don't have a fuel pressure guage you need one. You would have seen the pressure dropping to tell you there was a problem.

 

Very true

i picked up one mile per gallon on changing mine out, its no big deal, just get a few extensions, a ratchet, and a 17 mm socket i can have it done in less than 10 minutes, plus its really inexpensive to do so at 8 bucks a kit...

Geico makes a very good point, algae is caused by moisture and bacteria in the fuel so its best to get it out of there, and get a FP gauge in, even on a 12v they are nice to have, its nice to know what ur fuel system is doing... and if it is functioning as it should

I have been using B20/B40 BI0 for awhile would the fuel cause this?

 

Diesel algae caused by water in the fuel usually looks more like brown/green snot.

The black you're seeing is probably asphaltines, a normal constituent of all diesel fuel caused by uncracked or damaged molecules left over from the refining process. It's occurrence and amount is impossible to predict.

AKA "Fuel Bugs"

 

Infidel, this is from your link. Black can also be from bacteria.

Fungus and Bacteria -- these microorganisms live in water and feed on the hydrocarbons found in fuel. Called Humbugs for short, these active and multiplying colonies will spread through a fuel system and quickly plug a fuel filter. The fuel filter will have a slime coating over the entire surface of the media. Bacteria may be any color, but is usually black, green, or brown. Draining the fuel system will reduce microbial activity, but it will not eliminate it. The only way to eliminate microbial growth once it has started, is to clean and treat the system with a biocide.

 

Great I've got "Humbugs"

Thank's for the link infidel

 

Yes, but it is always slimy.
I haven't changed even one fuel filter in the last forty years that hasn't been black from asphaltines.

 

Its just harshly black not slimy, I have no idea when it was last changed.....

 

is your truck still not ticking? or did it re-surface?

 

Why do they (our trucks) "tic"??
