Need Help with 5.3 Fuel Pressure Regulator Vacuum Line!

Silicone hoses are a great upgrade! They handle heat and pressure much better than stock ones. Just make sure the inner diameter fits your needs.

I’m curious—does anyone know how these changes can affect fuel efficiency? Could I expect better mileage?

In theory, yes! Improved fuel atomization can lead to better combustion, which generally increases efficiency.

What about tuning? Do I need to recalibrate my ECU after making these upgrades?

Yes, recalibrating the ECU is usually necessary to optimize the fuel maps based on your new setup. It’s crucial for getting the best performance.

Sounds like I need to budget for a good tuner as well. Any recommendations?

I’ve heard good things about HP Tuners. Their software is user-friendly, and the community support is great if you have questions!

I once tuned a friend’s truck and instantly turned it into a fuel guzzler! Remember to monitor your fuel trims after tuning. Balance is key!

Haha, that’s hilarious but true! It’s all about finding that sweet spot in tuning—not too rich or lean!

As we consider all these upgrades, it’s fascinating how small changes in the fuel system can affect overall performance. It’s definitely something to think about long-term.
