  1. I am fixing to purchase a 1994 cummins 4x4 5-speed. On the top of the P7100/P-Pump there is the injector lines and delivery valves. What is the metal piece that attaches to the injection pump where the delivery valve goes into the pump? It is cracked and I want to know if it can just purchase 6 of these top pieces and just replace them? It is the front injection line that I noticed leaking through the crack.
  2. this was about a 100 miles ago or alittle less one of my powersteering lines were clogged and i clean and rebled the system when i putted the fluid in it i over filled it just a little bit but i just noticed this evenin that i lost about a pint and i can not figure out where its goin and also another think i noticed was the fluid was a light brown and it smelled like oil but i putted fresh fluid in it but i dont if this is normal but i purty sure it aint
  3. In short, yes. Though we will not have devastating results from not using it like the next generation cummins, it does help the lift pump and all parts of the fuel system. I noticed a ticking in my lift pump one day, dumped in some 2-stroke and it fixed it right up. Another thing I noticed was it does not smoke as much in the morning with the 2-stroke. Having the timing up, the beast hates the cold and smokes like a freight train until the EGT's are over 400, but the other day, I started it and couple minutes later went back over and said uhhh, wheres the smoke! All I saw was a blue haze instead of a white cloud. I am not exactly sure how 2-stroke can have such an impact on smoke with a cold engine but the results were obvious. I also believe it helps with MPG, the added power is enough to keep you off the pedal just a little bit more keeping you over 20 as long as you are under 75mph.
  4. So my gal has a bad leak coming from the power steering pump. Trying to figure out if the seals are available seperately or will I have to purchase the entire thing? And is there a diagram or schematic available some where online that will help us determine which parts we'll need if we can buy seperately? Thanks!
  5. Ok Gang... You all have seen the Dodge FSM book minimum pressure of 10 PSI. Well I started to do some thinging and relized even that is too low. Here lets take a look at a pic here... http://forum.mopar1973man.com/attachment.php?attachmentid=878 So now let assume your fuel pressure average is about 12 PSI which is above the 10 PSI minimum pressure. Driving down the highway at 55-65 MPH your going to be flowing at least 2-3 GPH through the pump. But now let add a twist to it. New situation... Going up to Seven Devils Campground its a 17 mile drive up a 1 lane dirt road that is steep. I'm dragging a utility trailer with 2 ATV's. Ok for the sake of the post we'll say the fuel pressure is still 12 PSI. Climbing that grade I'm going to be flowing 7-10 GPH through that pump which is a good thing because the high flow keeps the pump lubed and cooled. But now the weekend is over time to drive home. So on the way down I set the exhaust brake and put it into 2nd gear and let it limp down the rough old trail it take about 45 minutes to 1 hour to return to the highway. So now the whole way down the mountain there is 12 PSI heading into the VP44 and but now your not throttling much if at all coming down the steep grade. So this means there is no flow to the injectors... And the Overflow valve is closed because you need 14 PSI to open it. So basically there is no fuel flow. So now the electronics and the mechanical part start to heat up the stale fuel and break it down. Remember diesel fuel is a very poor lubricant anyways. So now you see this is really easy to burn up or damage a injection pump. Now I'm starting to suggest 14-15 PSI as a minimum pressure and 20 PSI as a maximum pressure. This now keeps the overflow valve open and the fuel flowing through the pump while its spining and keeping the VP44 electronics cooled... Any thought on this???
