Attention: TDR Forum Junkies 
Ok, I have a problem:
First off i make bio-diesel. Last week I added 10 gallons to the tank of my truck making about a 50/50 mix with the pump fuel in the tank. while driving into town, she started jumping, like there was water in the fuel.
-I changed the filter and water separator. No change .
-Thinking I screwed up the mixture I added 13 gallons of pump diesel, to dilute the h20, no change.
Parked her for the weekend, Monday she ran fine for about 3 miles, then started bucking again, then died.
- I put fresh fuel in the fuel filter, ran fine till that ran out.
-I pulled the return line off my FASS, got her running (ran fine at an idle), used the return line to drain the tank.
-Primed the filter and added 10 gallons pump diesel to the tank, got 4 miles down the road started to buck again.
Symptoms:
idles fine with occasional small buck.
bucks hard when under a load.
Fuel pressure (between FASS and injector pump) does not change (10psi)
More info:
Fuel lines, 1 year old
Injector pump 2 years old
Injectors (300hp Bosch) 10 years old
What is the prognosis? Injectors?
