Hi Derek,

Sure sounds like a suction air leak but with a clear return line then it must be partial plugged somewhere.

On my 7.3 PSD I use ATF type F at 1qt/100gal#2 and does that ever quiten down the injector noise as it's a very good lubericant. I've been using this since new so I'm keeping the system very clean.

I also triple filter my fuel, once at the pump into a aux tank then into a Racor 10micron then into a Dahl 2 micron into my main tank then thru the factory Racor filter. Even with the new fuel system you should see all the crud that I trap.

One of the best fuel system cleaners is Biodiesel. Guys that run B100 say they plug a fuel filter with in a short time, change filters then plug another one in about 1/2 of normal filter change time, then the 3rd fliter is back to normal of what #2D filter change was.

The only problem with B100 is it will soften non-biodiesel rated seals and hose to where they need replaced. However there is a question of just how long this takes to happen. Some of the early VW diesels guys report dropping a injection pump every so often (40k miles or so) but is that from them making a bad homebrew biodiesel batch or from seal failure? To shade tree to tell exactly why.

If that was my tractor, I would look at it from this point. I can't use the engine the way it is, so if I don't try to fix it with existing parts, I'm going to have to buy rebuilt parts.

I would then remove the filters, disconnect the feed to the injection pump, drain the #2 from the tank, run a full tank of B100 and re-circulate that thru the tank and line until clean.

After the tank and line was clean, install new filters, connect the injection pump feed, fire the engine. If that didn't correct the problem. then remove each injector line to each injector and clean them.

Being very carefull with part placement and settings and being very "clean" take apart each injector and clean with Berryman B12, then re-install. B12 will dislove carbon build up as you watch it work it's magic.

If that didn't help then your down to the injection pump. Same sequence.

The way I look at it, if I don't help the system, I have to buy rebuilt injectors and pump so the only thing I've lost is my time. The tank and lines will be clean for the re-built parts.

If I get lucky, my engine will run smooth again.

I would strongly suggest a full set of IH manuals before starting this project. YtMag sells a great set of IH manuals for a reasonable cost.
