wes is right.....by the time the fuel system has everything primed it should have self purged unless you have a leak somewhere allowing some air to get in........Marc

Studying my system a little...

After having a good study of my new (to me) 2003 Effie, I think Marc is right and it would have to be sucking air from somewhere before the pump...

After the pump there is too much pressure.... The system seems to be self purging as Guru Marc says, so any air in it from changing the filter or something is quickly run out. A little rough for a short time and done...

Unless, you have something a bit loose and it is sucking wind from somewhere upstream of the pump, you should not have lingering air in the system...

Regards from the Amatuer Mechanical Engineering Section in Oz....

Cool Air in fuel

I have been around big diesels all my life. I have had one with a bad fuel line suck air and run like crap. My intrest was raised at another ford diesel forum talking of ways to expell the air. They said the engine idled smoother and quieter after a return line bleeder was installed at the heads. I was given a plan for a separator that I mocked up in the solvent tank and built a full sized unit for $12.99. The F.A.S.S. filter and air separator sells for over $700.00. Where does the purging take place? Where does the air go? I have removed all the suction leaks and noticed a quieter engine. I hope to get my separator and pusher pump installed this week.

Ramsmoker, did you get your air seperator up and running? I would be interested in doing something like that to my rig.

Cool Air separator

Yes I did. This is a big bang for the buck. Smoothness like I've never had before. Quiet, sounds more like 6.0. Really widened the power band. EGT's are 200+ cooler at all setting's with my TS. I don't feel there is an injected engine on the road that wouldn't benifit from this!!!!!!

OK, I am a bit behind the times by design I think... But are you saying that air is always entrained into the diesel fuel, with no leaks in the system, just frothed up? So this frothed up as you travel, is what you are purging out?
I am always the experimental sort, and this does sound interesting... But if it was true, it sounds like a performance boost... For free!

Regards, Ranger

Cool air in fuel

To a surtain degree, yes. You can test real easy in the comfort of your living room. Take a can of Coke and a straw. Drink from the can then suck thru the straw. This is a little extream but you will feel the difference on your tongue. Diesel isn't alone in the air department. Any liquid drawn by a suction will gather air. That is a problem for injected engines. Most all have in tank fuel pumps to lessen it. Take a look at my garage pic's. That was 75% fuel and 25% air. I couldn't make it pass air to the supply line. I havn't done the hutch mod to the fuel tank and after this project i see no need for it. I wouldn't say this free HP but darn close.
