Rail pressure shutter

[podulkad]

6.4 with dual pumps 100 overs

When cruising or slowly accelerating the rail pressure fluctuates from 10-20k and causes the engine to shutter real bad. I have already tried a frp sensor and that did nothing. Any ideas?

Start with making sure your not losing pressure on the low side. What kind of dual pump you have? Do you have the fuel bowl delete?

Might have better luck posting in the 6.4 aftermarket section.

I do not have a fuel bowl delete, and it is diesel dr kit
