0088 is typically a death code... you can try doping it up with a good lubricity additive... you can try a programming update depending on what tune version you're on. But it's typically a death code

I've seen an 0087 code be nursed for many many miles keeping the truck doped up on power service, but 88 typically means HPFP time

What tunes-if any-are in the truck?

Just a time thing. Most likely hpfp is saying bye bye

Yes sir. 6.4s have a HPFP and a LPFP
High pressure and low pressure.
The low pressure is the one on the frame rail that most people replace with a air dog or fass.
