I’ve had numerous attempts at tackling this problem I have been having with my DPF. had it replaced twice now and just have my recall fuel pump replaced this morning . Dealership claims all my problems with clogged dpf and turbo under boost codes were due to this one fuel pump?

The recall on the CP4 fuel pumps has nothing to do with DPFs, its from the CP4 failing and sending metal fragments through the fuel system.
Unless you had a separate issue outside the recall your dealer is making stuff up to get you back on the road. To my knowledge I have never heard of a CP4 or CP3 fuel pump causing any DPF issues. There are tons of trucks having issues with DPFs and frequent regens, the dealers are scratching their heads on what to do. Their approach seems to throw random parts at the problem and hope it goes away which is not working out well. However, RAM needs to step up and get engineering involved to fix this issue.
What are your driving habits with the truck? Do you tow often? Also, what air filter are you running and when is the last time it was changed.
