ISC transfer pump

[Ncostello]

My volunteer fire departments newest rig is a 2000 KME Excel Chassis Pumper. The engine is an ISC 330HP Cummins. When I change the spin on fuel filter, the manual specifically states to install it dry and let the transfer pump fill it before starting. Fine. It works great. When I turn the ignition switch to the on position something senses its empty and the pump automatically kicks on to prime the system and purge any air. It runs for a minute or so.

Then I got to thinking, what kind of transfer pump is it??? Maybe it would work on ISB's. Its mounted along the back side of the engine very similar to the ISB but its mount is much larger. Its actually a junction block for supply fuel lines and the two return fuel lines (injector pump return and cyl head return). I was suprised to notice the motor looks awfully similar to the Carter OEM ISB electric pump motor. At least its the same size. I'd say the lines are 1/2" on the supply side. So now I've got a couple of questions for any ISC gurus.

1. What are the specs of this lift pump if anyone knows?
2. Have you seen or heard of failures like the ISB's have?
3. Is the ISC injection pump fuel or crankcase oil lubricated?

My concerns are two fold. I'm wondering if this pump would work and be more reliable on my ISB than the OEM Carter setup. I'm also concerned about the likelyhood of the pump failing (like we've all read about) and causing the truck to run bad or ruin the injection pump...at a fire. At least if maybe the injection pump is lubed by the engine oil it will be spared a horrible death.
