How to adjust excess fuel adjustment on the popular Med Duty diesels. Roughly covers 84-92s. This is not the fuel rate. That adjustment is on the rear most part of the pump, and will get a video for that ASAP. More info on my site, the Low Buck Diesel Power how-to site. The link is in my profile

Yes the fuel rate will go to 21mm giving you max travel The fuel screw is located on the back after the aneriod. Take the two screws holding the cap on (one will probably be a break off bolt). the no air plate have a 10mm nut with an 3mm allen screw this is fuel before boost. this plate will pop off. Underneath this will be (hopefully) 10mm nut and a 14mm nut sometimes it's a slotted screw. You'll have to hold both nuts turn them counter clockwise to increase the rack travel. One turn 1mm

Thanks for the tip. I would also like to lower the idle just a bit since it seems to be a little fast. Is this the adjustment that is right on the on/off solenoid which turns a lever? on my engine the 6.6 it is right below the back of the injector unit and is just forward of the throttle lever. Would you happen to know what rpm the 6 cylinder 6.6 engines should idle at?....maybe 700 or so?. thanks I never realized how cool you tube can be to gain valuable information about important things such as truck repairs ect.

@nevrenufhp 10 жыл бұрын

The idle adjustment is where the throttle lever rests. It takes a 10mm wrench. You have to do it with the engine off. Idle should be 650 to 700 in gear with an automatic, or in neutral with manual. Adjusting the full fuel on the back of the pump really wakes it up.

I turned my screw out 5 turns and it seems the same until i hit about 1500rpm then it feels like a boost comes on and a lot more power. I havent done the back bolts yet, but this seems backwards from what it should have done... Also i havent messed with timing yet.

How do you get the bolt out if it fell in lol Don't know if u noticed I did I have a dt 360 international 766 and I had it turned all the way and went to tighten the nut and the darn thing fell In how do I get it out

@internationtruck1965 The turbos are the same model, but the exhaust side of the 360 is a little smaller. You would be better off getting an HX35 from a Dodge/Cummins and getting a T3/T4 adaptor. The HX35 is bigger than the T04 that IH used. Yes, you can run a P-pump on a 360, it just needs the gear & hub, and adaptor. You can get those from Sheids or Hypermax, and possibly from a couple other places too. I dont have the part number for the vlave springs, but they are from Comp Cams.

I have a 6.6 in a f-600 and it will not keep the rpm's up when driving. It seems to keep running out of fuel in the injector unit or something?, I have changed all fuel filters, drained and cleaned the tank, replaced the lift or supply pump at a cost of $350. and it does the exact same thing as it did. It starts right up no problem and will idle perfectly but as soon as you start driving it it does not want to go above about 1500 rpm and it used to go up to and stay at about 2700-3000 rpm's easily. Please help me figure out what is going on?. I also did blow out the fule supply line going into the tank and tried running it with the fuel suction line immersed in a 5 gallon container of fresh diesel, ran the same and seemed to be starving for fuel? HELP!!!!!!!!!

@martiwoodchip4518 10 жыл бұрын

Hey funny you should say that!, lol. Yes I did replace the fuel water seperator once right before I drained and kinda flushed the tank out and so I thought it would be ok. After replacing the $350. fuel pump it had exactly the same syptoms so I drained a bit of fuel from the fuel water seperator and it was clean but then I took the damn thing off and looked inside of it with direct sunlight and low and behold it was completely packed with rusty looking shit filling all of the pleats on the inside!. So I guess I will dump another $50. for a new fuel water seperator cartridge but will first put a clear plastic bowl type of fuel water seperator in line right before the stock worthless one that ford was so happy to mount on their trucks. The stock one plugs up very quickly and cannot be inspected without completely removing it and visually inspecting the inside, just draining the build up on the bottome of this thing does little to no good. Bad design from ford motor company!. and thank you for replying so fast, I very much appreciate it. Marti.

Great video, how much added h.p does it add? My truck is a '78 international s1800 not quite sure what engine series other than it's a Detroit in a dump truck with a bottom exhaust. I want to convert it to a upright,if I straight pipe it will it sound better and add any h.p? can I turn the turbo up or adjust it?

@nevrenufhp 7 жыл бұрын

This adjustment only adds power in the lower rpm, up to around 1800rpm. Straight pipe adds noise, lowers exhaust temp, and helps the turbo spool just a smidge faster. With a diesel, when you add fuel, it makes more boost. There's no adjustment to the turbo. On some, you can adjust the wastegate to open at a higher pressure, and you get a little more total boost.

Normally an MW pump on a DT466 gets about 13mm rack travel. Taking it to 14-15 would be better than going to 21mm and the aneriod would still work reducing smoke. The method your using will surely give you more fuel. Just never seen it done that way. That screw lets the pump go to 21mm for starting, then the max stop engages around 290rpm allowing the aneriod to work.

I have done the top screw as high as I can and turned the star wheel down (thinking that was towards the back of the truck) and still plenty of smoke. so the last adjustment you spoke about was on the rear. Will that help this or not. if so, which way do you turn it? Thanks

@nevrenufhp 8 жыл бұрын

If the turbo and everything else in the intake is working properly, it will take care of most of it. If there's a leak, it will smoke pretty bad. Adjusting down the fuel will only make it a weak running turd. The main fuel is on the back, if you decide that's the way to go, but it's not running rich, it's just not getting the air it needs

@bky28 8 жыл бұрын

+Bryan Kingsbury , backing out the screw on top will gain power, but smokes pretty bad. Plus, it won't fuel the whole rpm range. The actual fuel adjustment is the nuts on the back of the pump, and I made a video for that too. The turbos they used are a sorry excuse by today's standards. There's not a whistle on most trucks, it's more of a moan.

@nevrenufhp 11 жыл бұрын

Back out the screw at least 5 full turns, but you can go to around 10 before it starts hitting the top of the pump. If you want gobs of smoke just take out the screw. The preload goes out for more smoke, in for less.

Problem solved!. After getting some free bio diesel I had problems with all kinds of crap being re-introduced into the fuel stream from settled debris in the fuel tank and after draining all fuel out of the tank and replacing the fuel filters and water seperator I thought the problem was solved but my truck still would not go over 1500 rpm and was showing syptoms of fuel starvation so I finally figured maybe the fuel pump went out?. After replacing the fuel pump it seemd to run great but as soon as I took it for a test drive up the road it became obvious that it was exactly the same as before. I could not believe it and blew the suction line back into the tank, it was clear, drained some fuel out of the water seperator and it was clean but after removing the water seperator cartridge and looking down into it with direct sunlight it became apparent that it was completly clogged with super fine rusty looking shit!. I guess the moral of my story is do not ever think that just because a water seperator is draining clear diesel that it is good when in fact it is most likely the culprit of a fuel problem. I then installed a nice big clear bowl Zee Line fuel water sepoerator before the trucks stock one and this way I get to see exactly what is flowing into my fuel system. the 1988 Ford F-600's with the 6.6 straight 6 cylinder engines have a very good sytem for the fuel with the exception of a undersized non clear water fuel seperator. If anybody has one of these trucks the first thing that I would recomend doing is installing a clear bowl water fuel seperator right inline before the stock $50. metal cannister type of unit. It was fairly easy to plumb and easy to install a bracket for it since there are plenty of pre-drilled holes in the frame allowing simple instal.

Fully loaded, it may get close on temps, but most of these trucks are recreational, so they can handle a bit extra. To do it all out, you would need to add a front mount intercooler, swap to a Ppump, and add a turbo. Then, it could handle running 400+ hp without worry.

If you punch down on the pedal at about 1200rpm or above, it will be just like stock. The other way of doing it(the actual fuel rate adjustment) will give the full power at all rpm.
