Just installed cat fuel filter on my '12 Duramax lml. Truck

Customer Question

Just installed cat fuel filter on my '12 Duramax lml. Truck is hard to start. Won't stay running very long. Stalls out after about 10 seconds. We continue to reprime and start it back up, but won't stay running. We changed the oil & oil filter at same time as fuel filter. Please help.

Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.

Can you keep it running if you keep working the primer?

Can you try another filter and confirm its sealed well?

This pretty much is a fuel issue and it looks most likely to blame on fuel filter used but there are other things that could also do this that are fuel related.
