Here is the template to trim the fuel tank tubes to clear the engine tubes--it may require some additional trimming to make everything fit like the Centuri instructions.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !

Thanks! That's a big help. I did draw up the "gas seal" using the OD of the exhaust tube, and the two ST-7 engine tubes. I should be OK there. I can test-fit the engine tubes into the cut fuel tank tubes to make sure they fit before it is painted and glued together.

Thanks again.
