I'm thinking about cutting a 5 inch diameter hole in my aluminum diesel tank
so I can get in there and scrub them front to back.
I suddenly realize there are baffles in there.
Does anyone know what the baffles look like?
Do they go from top to bottom or just part way up?

I wouldn't bother with this but I need to cut a hole for a fuel sender, so I
thought I'd make the hole big enough to get my arm in.
