since I fixed the check Engine light po171 and po174 by replacing the hose is there anything I should do since my truck has been running in a lean condition for at least a year based on the codes??
my air filter from last August has about 7-8 thousand miles.
appears I’m getting under 11 mpg.

Today check engine returned for po455 the oil and water light came on and the temp gauge dropped to nothing even the 4 low light illuminated but engine died . It would start and immediately die. Then nothing. All I had with me was fuel pressure tester and code reader . Finally it started and I drove it home . Po460 code when I arrived home.
fuel pressure with engine off was 15-20 psi
