1988 E350 7.3 Hypermax
Now that I am thinking about it, I wonder if my mechanical pump has been on the end of it's life for a while. Could this cause my van to run lean while under load? As I am climbing/accelerating, could the pump not be supplying enough fuel to make the engine happy?- Ballalu

Not many of my problems were fixed, but things were fixed well enough for me to drive it roughly 1000 miles over the summer for some camping adventures. But now with camping season slowing down, I would like to delve more into this motor. My EGTs...- Ballalu

Thanks for the information; it will be nice knowing what the norms should be once I get the motor running well again.

Hello everyone, I’m new to this forum, but have been browsing for the past couple of days. I am new to diesels, but have some basic automotive experience. My father will be assisting me with various parts of my adventure; he’s been an auto mechanic for 45 years, but doesn’t know much about...- Ballalu
