Please explain fuel and oil in the 6.0

[RoCkfiSh363]

Okay, I know this is kinda askin alot but I would really love to know exactly how the fuel system and oil systems work in the 6.0 . Please explain what the fuel does starting in the tank all the way to the combustion (pumps, lines, filters...ect.) and also the oil. From when it starts in the pan to wherever it goes and what it does ( pumps, HPOP, lifters, filters, turbo ect ect..) Haha, you can laugh all ya want, but I cannot get good answers from people I know, and I would love to know all the details. Thanx a bunch.

This is not everything but these have allot of info.

2003-2004
6.0L Bible Table of Contents

2005 -2007
2005 6.0L Bible Update Table of Contents

Powerstroke 6.0L Technical Intro Manual

PowerStroke repairs

Diesel Engine Diagnostic Guide

441 Diesel & Auto | Ford

All of the above have diagrams and such.


The fuel starts in the tank, gets sucked up a tube, then follows lines to the pump, filter, flows through lines to the engine mounted filter next to the oil filter. The fuel has the option (depending on temp) to go to the injectors or back to the pump to be resent to the engine mounted fuel filter. It does this when it is cold and as fuel is used, the pump will replace the used fuel while it is recirculating. It recirculates to gather heat by the engine and transmission until a certain temp that I do not know. There is a regulator spring on the housing before the filter that sends unneeded fuel back to the pump for the option to cycle back up to the regulator and used, or go back to the tank.

If it is or is not recirculating and/or being uesed, the fuel will flow through the engine mounted fuel filter, it is split to 2 tubes to the driver and passenger side fuel rails. The 2 tubes enter the 2 rails on the front of the engine, once the fuel gets to the 2 rails it enters the injectors.

Well, rockfish, how's the weather in Bend? I lived there a very long time. Now in Vancouver.

The links smokersteve listed are great info links. Book mark those. His explanation is pretty much right on. Get the fuel system pictures, and his post will walk you right through the picture.

Time to start thinking winter time habits!

Thanks guys I would have talked about the oil but I do not know the all of detail off the top of my head. There is a diagram in one of the links that has a full image of the oil flow. And most of the links show different perspectives for parts of the fuel and most of oil

Weather in Bend is pretty calm for now. Night is getting down to just above freezing but it's dry. Looking forward to a snowy winter hopefully,
