Daniel, no, the truck was not showing any codes. replaced the pump just as a preventative measure. my experience, gm fuel pumps are on borrowed time after 100k
Out of curiosity, was your fuel gauge reading incorrectly? I've got a 2009 Avalanche and when my tank is completely full, my fuel gauge reads slightly less than 3/4. Fuel range never reads above 380-400 miles even on highway road trip fillups at start, but I'd gotten over 500 miles per fillup in the end. I've got a P0446 code that the final possible solution is likely the fuel tank pressure sensor, so that along with my inaccurate gauge reading is leading me to the desire to replace my fuel pump assembly.
Good video On my old 03 s10, the fuel pump went out around 180k, left me on the side of the road. Slapped the bottom of the fuel tank with a wrench every 5 miles after that to get off of the freeway... lol I ended up hiring my brother in laws mechanic to do the job since he was close to where it broke down, and my house was still a good 30 miles away... My wifes 07 saturn aura, right around 200k the back of the car started stinking like fuel. I managed to drive that sucker dry before i did the job, leaked out of the top of the housing... Now the new to me 09 tahoe, has some miles. Planning on just knocking it out proactively. Any space right above the fuel pump for a diy access hatch? 🤠 One thing i love about my project car, a C4 vette, is that there is an access hatch if you remove the fuel door. From your vid, i can't tell if there is a support right above the fuel pump or not? I see my self breaking put the rivnut tool, and making it nice. 😁
Just did one today, same year, same model. But at my work with a lift and fuel tank jack. Was sort of a bitch to do cause everything in western New York Rots to shit. Fun job though it wasn’t so bad
Just my opinion but any original gm fuel pump with over 100k miles is running on borrowed time. However, a tired fuel pump will show signs. If it takes more than a few seconds to start, the pump is on it's way out
