Any comments about sediment bowls in the EFI system &#= 8211; are they an asset or a liability?

Though my fuel is gravity-fed to the sediment bowl and= the EFI pumps are after, is the flow-rate through the bowl exceeding its design= /application intention?

I have heard that a sediment bowl is not mandatory as = long as there is a drain at the lowest point in fuel system.

I ask because mine was leaking the other day at the se= al between bowl and rubber gasket – tightened up the thumb screw and it = seems to be okay – yes it was previously lock-wired, though maybe the thumb screw was not as tight as it is now.
