## Questions & Answers

**Q: Would this be a replacement on a 2004 suburban Z71?**
A: Worked on 2004 5.3 suburban. Wired it up closer to the engine bay. The old unit was too far down the line and the wiring went bad to ground. This is just a more modern version with a much easier install. They all produce the voltage necessary by the computer. You will need new fuel line for this install and the pigtail as they are different. Possibly use the old lines near the intake and route it back the manifold input. Or just remove all the old lines and start fresh. The old fuel lines were terrible on my truck and i had to replace the 170000 mile old pump anyway.

**Q: Is this 3/8 or 5/16?**
A: 3/8" In and 3/8" out

**Q: hello， I want to know the difference between 13507128 and 13577429 their prices are not the same ，i want to know which one should i buy？**
A: There are two versions of this sensor.   One has the ability to measure fluid temperature as well if your aftermarket ECU supports it.   Good luck!

**Q: Would this fit 2017 Silverado ?**
A: It's universal so yes

### ⭐⭐⭐⭐⭐ Solid sensor
*by S***F on April 18, 2025*

Almost got the more expensive one with the mounting bracket but decided to roll the dice after reading some peeps haveing issues out the box, luckily worked for me. Added sensor to a 08 non flex Silverado once hooked up was reading 10 ish % on pump gas, first fill up on E and percentage started climbing leaving the station. Side note I had to change injectors as well to run e, I went with 50lb. I’ll be changing fuel pump down the line.
