sevanson I assume that Ford neglected to check-valve the return fuel supply (that also seems routed through the primary fuel (horizontal) filter, so that what happens is that the tank level will continue to fill the "bowl". within the canister.

Where do they get these engineers? The same collage as those writing the documents (owner's manuals)?

Let us know the final report! PLEaSE!

Thanks Hydro,

I played around with the app a bit and discovered that's a dead end. I definitely like the idea of an electronic sender as apposed to running line to a mechanical. I'll look into that.

About that...

I am using DashCommand and still have a lot to learn about it. But I see that it has a PID for Fuel Rail pressure. Will that give me what I need to know, or is this about plugging into the fuel filter bowl with a real gauge?

The filter on the frame would loosen just enough to start sucking air and giving me issues. Caused for many embarrassing trips to the shop for diagnosing a no start issue for something silly not to mention probably some harm to injectors with sucking air.

Not a huge issue but just something keep an eye on with doing your own changes.

I am glad I'm going thru all of this after picking up the truck. So far, all the filters I've swapped were cheap aftermarket. I'll go ahead and do the transmission soon.

Yup - try <1/2 tank next time and you should be good.

jokester00 I know with my '05, if I have a full tank (or close to), it will drain WAY more fuel (1-2 quarts) than if i'm below 1/2 tank. I usually try to time my fuel filter changes when i'm below 1/2 tank (closer to 1/4). Seems to drain a lot less (1/2 quart or so). I have also heard from others that if you're not on level ground, that can affect it as well, so I do mine on my level garage floor for that reason too. Plus, my wife LOVES the smell of diesel as it wafts into the house LOL
