I have an immediate need for the number three fuel line from the P7100 pump to the injector. New or used will suffice, and I am looking for the fuel line to repair a daily driver. Do you have one, or any suggestions for a reliable source. Any assistance will be gratefully accepted...

At the end of the accelerator rod, next to the injection pump is a pull spring. When I had to replace a broken accelerator rod, this spring was "hanging" loose. I cannot find any place that looks like it should be attached to. These two photos show where the spring is located on the...

Traveling across Kansas along I-70, the EGTs started rising to 1250 where the had normally been around 950. There was also a noticeable rise in the coolant temperature. Where both the OEM and aux gauges never rose above 190, they now reach near 210. There is also a loss of power and/or...

In the past there was a member who reported using Radio Shack resistors to keep the check engine light from coming on when the EGR valve was removed. He had also included a diagram. Does any member remember who the person was or where his article is located. I am apparently not using...

Because of an electrical problem with the brake lights, I have to disconnect the battery ground wires. When the ground wires are re connected, the brake lights come on steady or the will flash. I have checked the brake controller and it is working correctly. All other lights and accessories...

I am not sure what it is called, but my Idle adjustment rod snapped in the center. Appeared to be from usual wear and tear---the break was rusty with exception of one little section of bright metal. This is the rod on 1997 12 valve Cummins Engine. It is located between the injector pump and...

I'm having issues with my engine temp. AFTER installing a NEW water pump (the old one leaking) and installing a NEW thermostat, my lower hose is hot while the upper hose is cold. Water is flowing freely through the block, and the radiator was pulled and flow tested at a radiator shop and...

I am about to get my 97 dyno tuned. They asked if I want to have it mapped. Dumb me, I do not know what they mean by mapping "it". Thanks.

I purchased my 1997 used and have no idea what the previous owner did or did not do. Is there any benefit in taking the truck to a dealer and having the software programs upgraded??? Thanks.

Getting ready to swap out my K&N filter for either an AFE or an AIRAID CAI. Doing a topic search, it appears that the TDR people here like the AFE best. Is one better than the other? Then, when I scrubbed clean the K&N today, I also pulled the induction tube off of the turbo. The...

Leaking injectors I searched the archives re leaking injectors. I could not find an answer there. Traveling NC to OR and injectors leaking damp at first and now about a 1/2 cup. Can the injectors be tightened to stop the leak till I get back to OR? Will new copper washers stop the leaks...

I have been stumbling around the site looking for TSBs. Do we have a library of them here at TDR? Is there another location that I might find them? Thanks...

Just for information, I just had the fifth gear nut tightened or put back in place in Oceanside California. I went to a transmission shop, it took four hours, and cost $300. 00. They did have trouble getting the cross member down, and they did use a hydraulic spreader between the frame...

I am trying to locate the DPFE Sensor. Does anyone have a drawing?

The check engine light came on, and produced code P0401, EGR flow insufficient. I have cleaned a sensor on the intake manifold, I have replaced the vacuum switch, I have cleaned the crude out of the vacuum EGR diaphragm thingy, and it now opens and closes when operated by a hand vacuum pump...

I had no idea I was going to make the TDR Journal with my problem. But I want to thank everyone who responded for their suggestions. My original loss of fifth gear seems to have been related to a larger problem. We had to replace the whole clutch assembly and have the five speed rebuilt...

I am trying to replace the rear axle seals which are weeping gear oil. I seem to be unable to find the correct socket. Can anyone tell me the size of the correct socket/wrench or if I need to get a special tool? Thank you.

On my way across Arizona, there was a sound like taking a transmission out of gear, then the engine revved to higher RPM since I had my foot on the fuel feed. Now I have no fifth gear or overdrive. Can you tell me what the problem is? How can I correct it on the road? Is this a...
