DD15 broken fuel pumps

I had found metal shavings in Davco filter 2 years ago. I removed the shavings and replaced the filter. Last month they replaced the injectors and PLV and 1 box because of emission related issues.Truck runs fine and has no codes. Do you think my fuel pump needs to be replaced.
Truck runs fine in summer. In winter I have to add HOWES or it wont run. Plz advise. Thx

 

Shavings may have been just from when tanks were new, or if someone added something where they drilled into the tanks.
Not running in winter is odd. I had a 1998 Series 60 that did something like that. Turned out the seals were shot in the fuel pump and allowing oil to get in the fuel system, so it needed the fuel treatment to run right.

 

Just add 2 cycle oil - $14.00 at walmart per gallon, add 1 gallon per 128 gallon of diesel. Engine will run very smooth, as never before....

 

I clean the injectors with this on my s60. The military put 2 cycle oil on their diesel equipment. The formula is half to one oz per gallon of diesel. I don't think you will plug the DPF. This is a TCW3 oil, ash less . It is used on all 2 cycle marine motors. No I never tried on dd15 EPA 10.

 

My truck had the same issue, along with three other company trucks here. The mechanic at Freightliner said he has seen the issue with several of the same model year trucks. He claims it's a Detroit issue, and they know about it, but are ignoring it.

 

The mechanic said once they replace the OEM fuel pump with an aftermarket pump they have no more issues, but you really sound like you know your stuff so I take your word for it. Note the sarcasm

 

Cannot open file.

Buying fuel at the major chains only is a good thing. I've noticed The J, Peelot, and Love's are using more strait up #2ULSD. As where TA / Petro are using a lot more bio. And mine definitely runs better on the pure fossil.
