T&T: Dual Racor Filter Question

[Steve Burgis]

I would like to change my existing single Racor diesel filter to a 75500MAX
dual filter.

 

The Racor catalog says "A single valve on all the double manifold MAX models
isolates one filter/separator for service while the other keeps
operating..."

 

If I shut off both the inlet and the outlet with the same handle, how do I
refill the filter body (remove the air) if I drain off water or change the
filter element before returning it to service.

 

If I replaced the filter element, assuming fuel is available in the line, I
would expect to allow some to flow into the filter before replacing the top
and then opening the outlet.

 

Am I overthinking this?
