Fuel tank construction

[Coburn_Performance]

Extra safety factor. It's not a hot rod, so there won't be mirrors under it at shows. I've analyzed many fuel tanks on this model of car and it's the leading edge that gets hammered - so that's where I put the protection, form following function and all that stuff.



Back on topic, has anyone done the calculations (I didn't know where to start) for sizing the holes through the baffles? I've seen many baffled tank designs where the ports look way too large to stop fuel sloshing around. In my tank, I decided that given the size of my engine (fuel consumption) and the volume of the pick up that cutting the corners (only) of the baffles (there are 2) to allow 1" square per hole would be more than enough to allow the tank to supply fuel to the pickup no matter what the road/track conditions would be (sure it wouldn't work if I was driving counter-clockwise on a high banked oval with an empty tank...but that's not likely to happen). There's no going back now - but for reference for someone building a tank, is there another way to work this out?

What about adding a full bottom rock pan instead of bed liner. Why hide all of that great work with rubberness.
