Our flat-back IMFOs are more common on smaller tanks generally around
a thousand gallons or below.
With the flat IMFO, if you've ever removed it to replace a gasket such
as what we've done here today, it's fairly simple to put it back on.
You get your gasket up against
your IMFO with your ***.
We'll run our bolt through.
Our backing ring
will go right up against this.
A dab of anti-sieze,
a flat, a lock washer,
and a nut,
and we'll continue at all four
hole locations. We've got our full set of hardware
now wwe'll utilize our torque wrench set at twenty-foot pounds
to tighten each bolt in a criss-cross pattern.
