FCA similarity between ISB and ISL

[E7mack96]

I have changed out a lot of FCAs on the ISL engines at work. they are identical externally. Can someone tell me if there may be a "larger" flow area inside the ISL one?



The part # is different between them, and the isl version has a pigtail lead connected at the normal location that adapts to the engine harness.

sounds like a good question for a Cummins engineer

Doesn't II have an ISL pump they sell that is like 200% more flow than the stocker for the ISB?



Might be worth a try to see if the FCA duty cycle would match close enough to the stocker to just work and flow more fuel.



I wonder if the Cummins and Dodge engineers would answer questions like that on the tech talk?

I took the ISL FCA apart today, and internally it looks to be the same. I would have to have a dead isb one to compart side by side as far as the triangle opening on the internal sleeve. I will post a pic of it soon.
