GM High Pressure Fuel Pump Replacement 5.3 & 6.2 ( Complete Guide)

In this video I showed the steps and procedures necessary to replace a high-pressure fuel pump on a GMLT motor this includes 5.3 and 6.2 L motors found in GM trucks SUVs and cars. That particular truck working on is a 2015 Chevy Silverado equipped with a 5.3 L. The issue that were seen is that the fuel pump seal has failed allowing fuel vapor and droplets to go into the crank case. The PCV system on these motors will pick up the fuel vapor and allow those vapors to go into the intake manifold making the engine run rich. Which in turn causes P0175 and P0172 to occur and the check engine light will illuminate shortly after. Make sure to check out the links in the description for the parts and tools I use during this video. Thank you for watching
