A while back I mentioned I was pretty sure my fuel pump was leaking (57
Dodge Coronet).
I was able to determine that fuel is actually spraying out the top of the
pump. From the service manual it appears to be Fuel Pump model
M2502S. The fuel appears to be escaping from the oval opening in the
rocker arm housing (at the top, furthest from where it connects to the
car). Looking at the exploded view of the pump, my first inclination
is to say the diaphragm is bad (or headed that way). It does still
pump gas (seems like a pretty good flow too), but clearly there shouldn't be
fuel coming out of the top of it. I suppose other possibilities could
include some of the internal pieces are going bad, but in my experience with
aquarium air pumps, the diaphragm is always the first (and usually only) thing
that goes bad.
I guess I'm just looking to confirm my suspicions (or the exact issue), and
then figure out the next step. A rebuild seems pretty simple...this from a
guy who is only looking at a schematic and has never attempted one. If
anyone has a used or rebuilt pump available, throw me a price.
Ideas or suggestions are appreciated.

PS- Anyone in Central Ohio want to buy a 90-gallon aquarium or two?
They are preventing my Dodge from being housed in my
garage.
