[Mgs] Banjo fitting on H4 Carbs

[Robert J. Guinness]

I am rebuilding my MGA's H4 carbs and I think I have run into a DPO 
bodge.  The banjo fitting to the float bowl covers  (Moss part #370-140) 
have two different "faces" (one where the bolt goes through, and one 
where it mates to the float bowl cover).  One face is indented so that 
the gasket fits within the indent.  The other is flush.  My question is 
this.  Which "face" mates with the banjo bolt head and which one mates 
with the float bowl cover?  The banjo bolt has a circular ring under the 
hex head.  This leads me to believe that the indented face of the banjo 
fitting should mate with the bolt so that the circular ring under the 
hex head presses into the indented area.  Since the float bowl cover is 
flush, it makes sense that the flush face of the banjo fitting should 
mate with the float bowl cover.  However, my existing set up is the 
other way around.  The manuals don't have an answer.  Does anyone on the 
list have an answer to this potentially leaky problem?
