Craziness! Why do people recommend crazy aftermarket mods to fix simple problems? At 174,000 miles, you need a new fuel pressure regulator. The poppet wears and it will not hold pressure like it used to. Your truck is doing pretty well on pressure for that many miles honestly. Your fuel pump is fine.
Diesel o rings sells the kit you need for $70. No need to swap out fuel pumps or hpops.
Ohh, do NOT do the bb mod. No matter what you read, do not do it. Spend the $70
Nonconformist. Functionality over bling.
My three rules for 7.3l troubleshooting: 1) Replace CPS and keep a spare. 2) Replace FPR and know your fuel pressure. 3) Hook it to a scanner and check for codes.
