So just curious is there anything else that could cause low trim on an injector? Or does that just pretty much point to the hpfp?

Ok after emailing back an forth with mike from spartan diesel and talking to the tech working on my truck. I decided to go ahead and change the hpfp. The injector is out of spec. I'm getting the repair done cab off. To have one labor bill i'm having them put head studs in and they said it was no problem to do the egr & cooler delete. We believe hpfp pump is failing hence the change of pump and since one injector is acting up and needs replaced I'm just going to have them all changed. Figured again one labor bill and since one is out of spec and with failing pump others might not be far behind. Is there anything else i should consider while the cab is off? Thanks for all the info and help.

I gave you the best advise about how to handle your concern, that was to file a claim for water damge caused by bad fuel.

Yeah, start the claim as I don't think ford is going to warranty it.
Unfortunately the HPFP has to be turned in as a core, otherwise it would be nice to open it up and have a look. |
Open it up, look at it, put it all back together and return the core. The pump is the best place to find water damage.

Rust spots or signs of lack of lube. When you do it post some pictures and I or someone that knows what they are looking at /or for can help.

Just some thoughts I had. If I find damage in hpfp from water. How do I prevent this from happening in next hpfp?? I drain the water separator once a month religiously. Change fuel filters every 10,000 miles. Always run a fuel additive in every tank of fuel. Yet still hpfp failure?

Many places will put emulsifiers in their tanks, thats bad news.
Buy fuel from very busy stations. |

After my clogged separator scare, I have gone to draining the water separator every 2-3 weeks. I have yet to get any water out of it but I drain out about a quart of fuel out of it anyway. I have also gone to changing the fuel filters every 5,000 miles instead of every 10,000.

There's a couple pics of the rocker arms on the driver side the coser pic shows what i believe to be a really wore down nub/tip on rocker arm. Is it better to try and change just the wore ones or can you get the whole thing as a unit? Also where would be a good place to get something like that? |
