Might be awhile before we hear from him...I'm guessing he's parting too much now that his high plains ponies are headed to the Meadowlands next month. The boy, well he isn't taking it too well that Brady couldn't pull it off...again. Speaking of Mr. Moderator; as much as Scott hates to admit it...there is allot in common between the 7.3L (PSD) and the 6.0L when compared to other PSD engines. Both use HUEI style injectors (the 6.0L are smaller) and the associated high pressure oil systems. The biggest difference of course is the displacement and variable geometry turbo on the 6.0L engine. Jeff was it you that that made the comment that you drove a IDI powered F250 home with dead batteries several years ago? Seem like the only thing that was different was the engine wasn't showing any oil pressure on the dash. Maybe it was another member of FTE

Wasn't me, and that could be difficult as it does have an electrical shutdown solenoid in the pump. Not sure at what voltage it wouldn't have enough pull to keep the engine running though.

Maybe just a couple of volts would keep the relay energized? But not enough to power the gauges??? The more I think about it...I think it was in the 6.0L forum and there was a comment/thread about the fact that if the LPOP (low pressure oil pump) down in the oil pan died...the engine would die before damage was done to the bearings. I can only assume it's some-what similar on the 7.3L...but on the 6.0L, the LPOP feeds the HPOP which creates the pressure needed to fire the injectors. Thus, if the LPOP died..no oil to the HPOP...and no pressurized oil to fire the injectors. I know, more than most of you ever wanted to know about a 6.0L PSD.

I hope this link works....if not I'm going to have to figure out a way to get it to work. This is using your Ford in a way Dearborn did NOT intend.

... that's definitely a new one for me, with that airplane. I guess it's the same kind of thinking for a push-start though...

Oh, and IDI fuel shutoff solenoids close at around 10 volts. I forgot to hook up a voltage regulator once, and the truck drove for a good 500 miles before my mother turned it off because the headlights were too dim for her to see anything. Didn't hurt anything other than my pride...

Only in Arkansas...70F for a high on Monday; 36F for the high 24 hours later. At least the weekend is still looking good on the extended forecast.

Harry, it ain't nice to tease those of us still stuck working and not retired like some folks around here. With everything your dragging behind your rig...good thing it's a 6.0L

What are you doing still awake at 1am?

Nice set-up though; looks like it would work perfectly for the beer and pop.

You do not. I said an early PSD can be chipped. An IDI can not.

Heck, a brand new HPOP works better with fresh oil. 7.3's seem to be fairly oil sensitive. My truck will drop nearly 2 mpg if the oil goes past 6000 miles. Comes right back when I change it.

TGIF!! I know nothing about diesel's. Is the 7.3 better than the 6.0 ?

If you thinking your having a rough week...this is what I've been dealing with at work since Tuesday.

Broken Bridge Shuts Down Rail and River Traffic | 5NEWSOnline.com

I know just from the railroad side...it's getting expensive with the backlog of freight needing to get across. I hear the barges are stackin up and it's even more expensive.

Could have sworn you said otherwise...but looking back, the evidence isn't there. Strange.

Yet another reason why I agree Ford got it wrong when they claimed you could go 7500 between oil changes on these HUEI engines. There is a guy in the 6.0L (from KC) that hauls RV out of Indiana all over 'Merica. I wonder how often he changes his oil? The last thread I read that he started...his motor trashed a lifter at 570k miles. I want to say he's got an '06...but I'm too lazy to go look up the thread right now.
