I’m looking at the possibility of replacing the puny 24 gallon fuel tank on my ‘21 Silverado crew cab. I think GM really missed the mark when they decided on this size tank as the only option. I understand this is an EPA-based decision, but Ford and Ram both offer extended tanks as an option. I’m tired of filling so frequently . The only solution I can come up with is to buy an aftermarket diesel tank (offered in 43 ga capacity) and swap out the factory tank. Anyone had any experience in such a mod or have any suggestions??
