Here is the deal (2000 Excursion, 7.3, 200K)
A few weeks ago, I installed the Driven Diesel Regulated Return (set to 62 psi when warm). Ran great, smoother engine, a little extra power, etc...
This weekend, I installed the Driven Diesel pre-pump fuel filter kit (the "Hutch" mod + a Baldwin fuel filter and new line to the fuel pump). I cycled the key about 7 or 8 timed to prime the fuel system and started the engine. I ran rough for about 5 seconds and then seemed to smooth out, just like it did when I put on the regulated return. I gave it some more throttle, but then it seemed to "choke up," white smoke out the exhaust, etc... I then took it out for a drive, assuming it would smooth out, but it eventually died about 1/2 mile down the road. Called the tow truck...
Today, I partially dropped the tank to see if I pinched the new fuel line. Nope, it is fine.
I then got a fresh 3 gallon can of diesel and put in a temp line before the pre-pump filter. I ran the truck directly from the can, thinking that I incorrectly installed the "Hutch Mod" from Strictly Diesel and was restricting fuel flow. Result; same problem as before.
Next I put the temp line and can in right before the fuel pump, thinking that the new pre-pump filter might be restricting fuel flow. Result, Still am having the same problem.
It seems to idle fine, but starts to bog really bad/white smoke whenever the throttle is applied.
Is my fuel pump toast?
