Any time 2 dissimilar metals make contact with out a barrier betwenn them, the weakesty of the metals will corrode. If u take a 2 part epoxy primer and coat both metals, it will greatly reduce the chance of corrosion. In aviation, it is required by faa standards and maintenance practices to coat ALL metals being installed on the acft with an epoxy primer. Using an all steel tank, a fuel resistant primer can be used, as long as the metal has been preped before application of primer. Alodine or muratic acid will work as a preping material. Once the tank is primered, use a fuel resistant paint n apply several coats n that will great reduce any corrosion of steel tanks
