09 6.4l powerstroke p0087

i have an '09 f350 6.4l powerstroke that keeps throwing p0087. Seems like it runs good till the throttle gets to a certain point then acts like its starving for fuel and throws code and striaght to limp mode. It has dpf and egr delete, sct tuner, 4" turbo back exhaust. i dont know if its low pressure fuel pump not supplying fuel to hp pump or if its the hp fuel pump going out. Any ideas would be great. Fuel filters have been changed.

Dose it with Quart of power service silver. I've seen it unstick the regulator in an hpfp. Truck is still running great. Owner uses 16oz per fill up now

Running into very similar problems. Just had the truck in the shop and ran through. Ran great for a month now seems like starving of fuel at highway speeds when trying to accelerate. Any resolution found with the Power Service Silver?

power service usually helps out a sticking regulator... if the pump simply can't keep up with demand under power, it's not going to fix it

are you sure the shop you're using is changing both fuel filters every 10k miles and not just the one under the hood?

I've been servicing the fuel filters myself. I've noticed top is normally great and bottoms dirty. Bottom got changed last night and left top alone. And doing about every 8,000-10,000 miles. My CEL hasn't come back on today but I have a loss of power anywhere from 2,500-3,000 RPM. I'm just trying to eliminate possibilities to see where my issue is.

What are you monitoring with?

The problem with PS is it cleans... It cleans very well... Drunk is right, on occasion you can fix a sticky regulator but if that's already a problem you have a lot of other crap in the system. When all of that sediment, deposit, and whatever else is in your fuel system/hpfp ends up becoming dislodged it has to go somewhere. Where is that fuel supposed to go??? Injectors... If you are already having issues the hpfp is probably already on its way out. Its kinda like stiction on a 6.0, once its there you can deal with it for a little while with archoil. But eventually you will be replacing injectors. It is just the way things work.

As for your loss of power, we need more to go off of. Personally, when you consider the fact you already have a fuel pressure code... It means to me your hpfp isn't long for this world. Could very well be you got water past the hfcm or some other debris got in there. Again, without knowing numbers its very possible you have other issues causing your top end performance to tank. Now might be a good time to drop into a shop and have it properly diagnosed. I would start saving for that hpfp, and you really do want to catch it before it grenades. Its a lot cheaper to just replace a bad pump that hasn't taken the rest of the fuel system with it. Those injectors aren't cheap and neither is the labor to flush the tank and lines.
