Ummm... How? When I plant my foot to the floor on 5x5 I'm running or using is one in the same. The only reason I'm running 5x3 is smoke control. Same amount of fuel. The sublevel 3 is 67% of stock fuel till 10 PSI then cut loose with level 5 power.

Stay in touch and keep us posted on that pump I'm curious of the life span and performance of it.

Master/slave unit from NAPA is like a $110 bucks and you have to bleed yourself. Still running mine years later. (Soutbend ConOFE Clutch)

:lmao2:Internet myth... I ran 5x5 solid for over 2 years and got good MPG numbers and no issues with my VP44 injection pump. I've got nearly 200k on my VP44 injection pump now and still rolling just fine.

I've got a member (Towhungerford) that called today and is having problems with a 2003 Dodge Cummins that has a knock while under load and goes away after it warms up. The injectors where just replaced and the knock came after the injector replacement. The injectors where replaced because of hard starting issues. But now there is a audible knock while under load cold but as the engine warms up the knock leaves. Got me scratching my head.

Bad cab grounds? Check the grounds at the driver side kick panel and the grounds under the hood on the driver side.

I agree with MnTom the tank vent on top on the sender is plugged up.

Usually the fuel pressure on the WOT will drop with a dirty filter where demand is the highest.But if the coolant temperature is high your idle could drop lower causing a drop in fuel pressure.

Or is it like the old stock Carters that just return the fuel flow back to the input side? Re-circulating the fuel from output back to input.

Anytime a clutch hydraulic problem occurs it just best to replace both master and slave. I typically just go to local NAPA store and buy master and slave and bleed myself. Hang the whole unit from the shop ceiling and let gravity do its job allowing the air to rise while pumping the slave cylinder rod.

5x5... Sounds crazy but the higher the levels and sublevel the earlier the timing is given so all you need to do is keep you foot off the throttle.

Typical average between 500k to 1 million miles. So have go much farther than 1 million without a rebuild. Since rebuilds are very rare and most that fail before this point are from pushing to hard so they end up doing custom building at this point. Once again rebuilding is not common place unless you planing on going big HP/TQ which requires upgrades like cams and such. But most people can do their own rebuilding its just the machine work should be done it a shop that's typically handles diesels.

Don't let your last repair hang you up too much sometimes thing just happen to fail at the same time of the failure too. So double check your work but don't let it hang you up too.

I would look at... [*]Wheel Bearing [*]Brake calipers (Make sure the caliper is binding up) [*]Brake hardware (bolts, caliper mounting, etc.) [*]Front axle u-joints I've seen over time where brake calipers bind up rub the rotor excessively and after sitting all night and cold rub and do weird things. I've had a report from anyother Dodge owner that was losing the hardware to the caliper and allowing it to rub at a weird angle.

Double check...MAX A/C, A/C, BiLevel, DEF-Floor and DEF modes are A/C used positions.Floor and Vent are without A/C. A/C system will naturally cut out during the winter because the low side switch will not allow temperatures below 32*F and hence so when the weather freezing cold the A/C is most likely disabled by the low side switch. On humid cool days the A/C will naturally dry the cab air out and reduce fogging of the windows hence why its setup the way it is.

:iagree:I would just replace the sender for a small price of $70 or so bucks. Yeah the vacuum motor is mounted under the driver side battery and usually gets rather ate up from the battery acid. As for the hard starts. If you got a mechanical fuel pressure gauge and to watch it when you first crank it up will give you a clue of a air leak issues. Because at key ON most see a quick burst of pressure with a air leak there will not be this burst. Then as you go to cranking typically 7-12 PSI is normal cranking pressure you'll most likely not see this but lower till it pushes the bubble out then jump up.Common air leaks.Crossover tube O-ringsReturn fuel banjo at the back of the head.Return fuel Tee at the back of the engine.Suction line from the tank to the lift pump. (Pressure lines will always leak outwards when pressure applied)

Way different that old school AirDog 150's... The only problem mine had was cramming the check ball back into the coil of the spring which I fixed by egg shaping the last coil. Very stable. But looking at Raptor's adjustable regulator there looks to be way too much stuff to bind up, stick, wear out. Compared to mine its just a plastic ball coated in rubber. Lots of steel on aluminum http://forum.mopar1973man.com/attachment.php?attachmentid=6101

Could you explain the differences as well? I understand its a specification but clarify the difference between them both.

A drop in cetane (2 cycle oil) helps with increasing BTU's. Possible increase in manifold temp could help with MPG's as noted between these two runs. Warmer air does improve MPG's. http://forum.mopar1973man.com/threads/8290-I-think-I-finally-caught-up-with-ISX-for-a-day-run!?p=80081#post80081 http://forum.mopar1973man.com/threads/8290-I-think-I-finally-caught-up-with-ISX-for-a-day-run!?p=80399#post80399

Something about the Raptor/AirDog pumps and the adjustable pressure regulator... I've never had a chance to see or to play with one to see if there is something else that can be done to fix it.

May I ask what you know about NAPA / Wix filters and why you not fond of them? I was half tempted to switch over to them.

Current Today MPG: 24.0 I got a second shot at repeating the same trip. The only thing that changes was weather which was much cooler than the 27.2 MPG run. I travel basically the same run again as the first time. Vitals I can give... Cargo and Passengers: 2 on board (350#), groceries (80#), 1/2 Tank of fuel (1/4 tank less fuel) High Temp Outside: 80*F (25*F colder) Speed: 55 MPH or lower speed limits never exceeded 55 MPH. IAT: Forced to 143*F checked actual a few times and it varied from 110-115*F. (22*F to 23*F colder) Coolant Temp: 193-195*F Boost: 1.5 to 3 PSI on the flats and tried not to climb much above 10 PSI while climbing grades. EGT's: (450-500*F down) (550-600*F up) on average max'ed out at 750-800*F climbing 7% grade at 35-40 MPH (not count slowing down for corners acceleration.) Tire Pressures: Front Axle: 58 PSI - Rear Axle: 40 PSI (+3 PSI more) Fuel was treated for 128:1 ratio 2 cycle oil. Air Conditioning was on and used. Elevation: McCall, ID 5,100 feet approx. Home: 2,800 Feet measured. Riggins, ID 1,800 feet approx. Going up I used 4th Gear all the way from home to McCall, ID then at select times that I could I would use 5th gear on the way down. Same with the Trip to Riggins, ID I used 5th gear selectively and return home I used 4th solely climbing back home. Repeated as closely as I could.

You need to verify which gauge is correct. Use a IR heat gun and do a couple of quick measurements with the engine off after its fully warm and see what you get.

The Good Lord above was smart in designing the planet and the rules of nature. Yeah the smoke is choking at times but there is a simple law of science that can't be broken. "Nothing can be created nor destroyed." This means if you weight out every thing on the planet you can never make more of a atom or destroy it. Pollution is that fact there is not enough wind to dilute the smoke. Another phrase told me me is "The solution to pollution is dilution." The planet will deal with the waste products by degrading them over time, or converting to another substance like CO2 to O2 in plants. But what is really stupid is creating Wilderness Areas where man is not allow to take any machinery. Guess what most of the fires are burning out of control in most Wilderness Areas. Why? Because there is no one to manage the land and harvest the dead fall. More or less the Land of No Use. From what I'm hearing they are stretched rather thin at places now...

Check this out. Things are getting a bit smoky around here. Red flag warning for Thunder storms that are coming through.
