Fuel Filter Reduced Engine Power - Damage?
Hey Guys, first post here so thanks in advance for your help.
just puchased my first diesel super duty F250 last week and wanted to start fresh on the oil and filters. Truck is a 2016 F250 6.7 with 41.5k Replaced the oil and filter then moved on to replace both fuel filters. Everything went pretty smoothly and I started up to tow about 3k pounds down the road a ways and made it about 8 miles when I began to receive a low fuel pressure warning which manifested into a CEL for low engine power. I limped back home the 8 miles having to start and stop letting the system prime a few times to make it up hills and my gut wrenching the entire way. Issue ended up being a bad seal on the underneath filter O ring and easy enough to fix. At this point I have reset the check engine light and drove about 30 miles without issue but my question is what permanent damage may I have done to my fuel system or other? Am I okay or should I continue to be paranoid?
Thabk you guys in advance...

A dry hpfp will cuase impeller wear, which will appear as metal dust particles in your fuel filters. The high pressure rail system send unneeded fuel back to the tank and this sends the particles to the tank and gets picked up by the filters. The problem with fuel pump wear is it reduces your max fuel pressure capability...

I bought a truck that had fuel pressure issues that turned out to be previous owner letting a additive bottle cardboard get into fuel tank. It had issues tor about 4k miles before the problem was finally resolved by local dealer here. The truck did go into reduced power mode quite a few times. Once resolved the truck ran fine but less than 2k miles after the final repair the HPFP had to be replaced. Hopefully yours wasn't starved enough to cause any permanent damage.

Wow, I sure hope I didn’t... So is the way to check draining the underneath filter and checking it for “glitter”?

You have to pull both filters to check for particles.
Be advised...if there are particles in the fuel rail...it can cuase your injectors to get stuck in the open position and when that happens the open injector will burn a whole in a piston.
So badicalky, check for particles and if there are particles have it towed to a shop that can do fuel system repair.
6.x engines are not the kind of engines you keep driving at the first sign of trouble....you basically have to immediately pull over and shut the engine off.

Don't get discouraged yet. Take it to the dealer and spend the money to have fuel pressures checked. If your truck has under 60k miles and the pump is not at full pressure it could be covered under the emissions warranty. I wouldn't volunteer any information about changing fuel filters and having problems. FWIW, my pump did not fail. The problem was caught when it was taken in for a oil leak. They ran diagnostics and found the low fuel pressures. It was covered under the emissions warranty. FWIW...

Check all your connections - especially the fuel filter under the truck - tighten it until it stops. Also check the "quick connect" hoses on the filter in the engine compartment. You might also want to make sure the filter in the engine compartment is seated correctly and the top is sealed.
