Penetrating containment wall around hydrocarbon tankage? tankage, hydrocarbon, containment, wall, Penetrating

I'm working on a project where the engineers want me to penetrate the masonry containment wall of a diesel with a fill line. Now if this was a dirt berm type containment wall I know we can't do that ...could compromise the integrity in an earthquake. BUT I don't know if this holds true with a masonry wall? The engineers (young, REAL young) say "No Problem" but I have that gut feeling.
?Can anybody give me some direction on this?

For a pipe penetration through a masonary wall (I'm assuming reinforced concrete), you can put a sleeve larger than the pipe through the wall, with the pipe inside the sleeve and an expandable rubber seal to fill the gap and allow for some motion.??We just completed a 20 inch pipe penetration this way and it looks good!

I've done similar type penetrations doing that exact same type of design. BUT this is a diesel tank and if a catastrophic failure does occur, diesel will be 3ft deep in this containment area ...and this penetration will be under the surface at 1'-6" elev. So a rubber seal may or may not work, however this masonry wall is only 8" wide so trying to “cast” this pipe sleeve in the wall would be a problem, this project is in a seismic zone 4, and ambient temps get up to 130F.
My basic gut feeling is still to go over the wall or under it.

What's the problem with going over the wall,is it too high?

Wall is 5ft; I could do that, but not a "clean" way to do it ascetically. Actually I would prefer to go underground. Only problem with that is trying to get clear of containment wall footing.

Look up the Link Seal. I have used these fittings with styrene monomer, acrylonitrile, petroleum etc.Diesel would be a snack.

Go with the Link Seal, as Stanier suggests.??

SO nobody has a problem with this tank rocking-n-rolling in a zone 4 earth quake with 20ft section of fill line sticking thru the containment wall? Seems to me it would be pretty easy for that tank catastrophically fail and pull that fill line thru or knock a hole or section of the wall down!!? ...OR have I been watching too many movies? *G*

What′s he aestetical problem with a beautiful pipe running over the wall?
You can always paint it artistical,
whatever.
