Bigger fuel tank

[zac9028]

I got a 2024 Chevy ZR2 3.0 diesel, it's a great truck love the miles pre-gallon. A truck that gets 25 to 30 miles to the gallon is always a golden egg I got a titan fuel tank on it. I've read a lot of people saying that the fuel gauge doesn't work. I've talk to my tech and he said that as long as you don't feel it up the fill neck that it doesn't have the issue, I found that to be true as I have had this tank for over a year now.

I've never heard of any fuel gauge issues personally. I just fill mine up until the nozzle clicks, and I hang it up. Never a problem here. Welcome to the forum!

I have a question. I just bought my GMC truck and asked the salesperson if the service department would install the Titan fuel tank. He came back and said it would void my warranty. I had a Ford F-150 diesel and had a 40-gallon tank installed the week I bought it in 2019, and I never had a problem. Does anyone have any guidance on this? I want the 43-gallon tank installed, but I do not want to cause a warranty problem.

Welcome.

What part of the warranty would be voided? Fuel system or the fuel tank? If the aftermarket tank used the oem filter system, I don't see a warranty issue with the fuel system.
