I wouldn’t spend a bunch of money to get someone out to an island to look at this for concerns about pollution or the like.

I would do the plastic/pea stone recommendation, perhaps in combination with some simple non-expanding spray foam insulation to air seal it. What I would be slightly concerned about is to why this is happening. Is the hose pulling out of the tank? If so, I would want to figure out what is moving as that could be concerning. Or is it just the connection that failed? The spray foam should let you see if it pulls further by gapping in the spray foam. I would only be concerned if it pulls out significantly further. Until then, just deal with the smell and ensure dirt/runoff can’t get in the tank there.
Totally agree with your assessment. Line is probably moving due to frost heaves.

Surprised the line going in is exposed to elements and possibly even freezing in the pipe, never mind the earth around it.

If the whole thing is on a slope or something maybe the earth (protecting it) eroded away?
