Need help with 8.3 Cummings Diesel fuel problem

It is in a 1999 Frieghtliner. It runs out of fuel in the filter when it runs at 15-20 rpms. Have repaced all the hoses and the filter. Also tried running the hose off the lift pump into a 5 gal. gas can, still didn't work.

obviously your pump is the problem then.

And it is not a Cummings it is a Cummins
