Updating cummins isc engine cap pump and problems
It is a proprietary Bosch fuel pump and replacement will cost between 00.00 and 00.00. twobachs wrote: Every once in a while the engine will hesitate or buck so I had Cummins service the engine and check the problem.The symptom you are describing is air in the system, the on board system of removing air doesn't get it all.Might want to check yours out if its an auto, the way they are set up, the excessive wear will cause the throttle/tv cable linkage to come off the shaft and the spring will cause the pump to go WOT.Although its no powerhouse, it would be a fun ride @ WOT with no control, better hope the brakes are good LOL The 8.3 can be a powerhouse.Simple things like sliding the fuel plate can get it up around 340hp-ish.Then, adding a 3k gov spring kit, and advance the timing a smidge....long as it's the P-pumped 8.3(6CT). I'm not sure how to tell what pump it has but it is the factory engine in my 95 Ford L8000. I would love to figure out how to get a few more ponies out of it.It seems to be a tourqe monster but I would like to hear if anyone knows how reliable they are as well as longevity. The CAPS were about as failure prone as the VP44 in our trucks.And wouldn't you know it they used the same phony block mounted lift pump as our Dodges too!
The ISC engine also features very versatile engine ECM parameters, so customizing the engine to the application is quite easy.
Some popular parameters that can be adjusted are: 1.) Engine PTO settings: Can be programmed to allow preset engine speed (RPM) at the touch of a button.
This ensures that the engine operates at the preferred RPM when releasing load and operating hydraulics.
This CAPS pump was a computer controlled injection pump, with individual fuel lines to each injector. Among other differences, the most significant was the change to the High Pressure Common Rail (HPCR) fuel system.
The new fuel system eliminated the CAPS injection pump, relying on electronic controlled injectors to actuate fuel.
If so, then yes there has been a lot of problems with them leaking. The ease of replacing depends on if you can get to the pump from the top of the motor or have to go at it from underneath. Not an isc -but I did have to replace the fuel pump on my ISB - ouch., The fuel pump is a vp44 (I think) and it has a history of failures. No problems since, work was done over 5k miles ago.
