A few years ago I had a pair of aluminum custom gas tanks made by Atlantic Coastal Welding. They did a good job all around. I have another potential application for what will definitely be a CUSTOM gas tank and was trying to decide on the best material.
The boat is mostly used in saltwater, so I'm hesitant to consider steel. Aluminum is fine for ethanol blends up to 10%. My concern is that most of the fuel in this area is already 10% ethanol and I'm concerned that before too much longer E85 might be creeping in. Everything I've heard is that aluminum is NOT acceptable for E85. So I guess that just leaves stainless - and probably 316 SST at that. Am I missing something here? Also, how much more expensive is SST over ALUM? 50%? 100%?
