Personally I would set the software to run a tight vane to get spooled up so you can get to speed. Then open the vanes up to drop boost at cruising speed.

Sound great and all but you can't buy that valve. You have to get a reman'ed VP44.

Here is the guts of the VP44... http://articles.mopar1973man.com/2nd-generation-24v-dodge-cummins/25-fuel-system/437-bosch-vp44-injection-pump-exploded-view The only thing I can think of is the control valve in this pic #135. But never been reported as a problem.

Can you imagine hauling that engine up there? How about all the tools to just assemble that mill? Crazy... Wow!

Still worth keeping an eye on. The previous shop I worked for the owner was quick to use these check valves for prime issues on diesel instead of correcting the actual problem. I understand there is a lot of different parts and seals in all the different diesel manufactured but its always best to fix it than band-aid it. Eventually the band-aid will not cover the wound or in this cause the failure.

Now there is a antique. Wow! I love old history like that and just be able to sit in front of it and imagine what it was like back in those days.

Thing is the fluid might be changed out but did you flush the debris out of the system? Is it possible you got debris in the hydrobooster because of the pump failure?

Cummins Kit is a double lipped.

Got to ask though with all these custom steering boxes (redhead and similar) why is it I'm getting ready to cross a quarter of million miles and no issues with a stock box? Kind of like asking why am I going to cross a quarter of a million miles with NV4500 and no 5th gear nut problems.

Most can get the screw out with a socket torx and then lightly tug on the sensor wiring. It will come out far enough to allow you to unplug the sensor. Hook up the new sensor and place the screw in the hole with tool in the screw and guide the assembly back in the hole carefully. That's at least how I been told to do it... I've never had to change mine yet.

Makes me ask th question what is still leaking? Being that our trucks don't have check valve you added a check valve to over come a loss of prime.

Yeah you've got a lot money spent on your truck.

No. Just because of the bleed hole the air can bleed back through the bleed hole in the overflow valve. As for the return line its NOT submerged in fuel it terminated near the top of the tank where the suction line is terminated at the bottom of the tank. Let's say with the overflow removed the lift pump can barely pump fuel through the VP44 with 14-20 PSI its just a trickle. If the engine is cranking the flow is greatly improved.

I tend to agree with AH64ID... The positive cross over cable between the two batteries must be damaged. Possibly a bad ground cable too. I would do a voltage drop test and see which one is bad.

Ahhh... 4 or 5 screw in the top of the dash. Knee bolster has to be dropped to get the steering wheel dropped another 2 more nuts. Then pull up the cup holder and remove the 2 bolts and 2 nuts under the cupholder near the airbag module. Then just loosen 2 bolts at the kick panel. Lift passenger side up and swing to the seat. Use a cam buckle strap to hang from the grab bar on the passenger side. If your stuck call me I'll be home tomorrow.

If you can unload this by "hand" I'll let you take as much as you can unload. The Honda Rancher got a good beating today when one log turned side way and rolled down the ramp and into to the nose of the ATV. On top of that it roll the winch line up pulling the ATV down to the ground tweaking my wench bracket. Most of this stuff was so heavy that even pulling with the winch line was insane the ATV would stand on its nose and pull for all its got.

I would opt for a gauge check if you can see if the gauge is accurate. Air being sucked into the fuel stream might cause this issue as well.

I really hate to scale my trailer right now. I rather heavy. Not to mention I didn't shut down the engine much through the day and kept the A/C running between stops. But during unloading I did shut down the truck. I'm pretty sure I'm close to the weight of my RV weight.

After today's firewood haul I made a solid 12 MPG. At least I'm getting work done and hauling materials.

Back at it today. I've hauled six cords of firewood. Four cords went to a close family friend just down the road. Then seeing how slim the log yard was getting I figure I'd better jump into the pile too so I hauled another two cords for myself.

A Mafia Godfather finds out that his bookkeeper, Guido, has cheated him out of $10,000,000.00 His bookkeeper is deaf. That was the reason he got the job in the first place. It was assumed that Guido would hear nothing so he would not have to testify in court. When the Godfather goes to confront Guido about his missing $10 million, he takes along his lawyer who knows sign language. The Godfather tells the lawyer, "Ask him where the money is!" The lawyer, using sign language, asks Guido, "Where's the money?" Guido signs back, "I don't know what you are talking about." The lawyer tells the Godfather, "He says he doesn't know what you are talking about" The Godfather pulls out a pistol, puts it to Guido's head and says, "Ask him again or I'll kill him!" The lawyer signs to Guido, "He'll kill you if you don't tell him." Guido trembles and signs back, "OK! You win! The money is in a brown briefcase, buried behind the shed at my cousin Bruno's house." The Godfather asks the lawyer, "What did he say?" The lawyer replies, "He says you don't have the guts to pull the trigger."

So people have found that the return line can draw air in but the air allows the prime on the VP44 to be lost. Now the weird part is the return line is not submerged in fuel but hanging at the top of the tank. So the return line should be dry technically. But if the VP44 is able to use the air leak for back draining the fuel to the tank then prime is lost. The overflow valve does have a unsealed hole.

I've been enjoying the 20-24 MPG back and forth to work. Just depends on if that day I decide to hype-mile and drag my butt to work or do I just set the cruise for 65 MPH and haul tail to work. Still with $2.839 price for diesel and $3.129 for gas... Yeah I'm enjoying it.

Temperature is possible as fuel cools the pressure for electric pump typically goes down. Like start of the morning 48-55*F I show about 1 PSI lower typically. Now on my trip home from work after sitting in 105*-110*F temps the fuel pressure is about 1 PSI higher. As for altitude there is no effect on my ISSPro EV2 that I've seen.

I HIGHLY suggest against using any noise filters... What you may do is protect the PCM from the noise but end up killing the VP44, ECM, ABS and other computers with bad power. No, There is no way to properly filter the alternator other than replacement because the diodes are fried.
