Jeff, I have a drain at the lowest point
in my system (my ½ pint header tank) that has served me for 10+ years.
I have a coarse filter before my header tank and pumps and fine EFI filters
after the pumps. I rather doubt the sediment bowl would seriously impede
your fuel flow (unless its for a lawn mower engine {:>))

bowls in EFI fuel systems
Any
comments about sediment bowls in the EFI system – 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 seal 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.
