190E 2.6 1992:  Just pulled cover, to replace fuel filter and found a
cruddy mess inside.  Dual fuel pumps right, fuel accumulator left, fuel
filter center.  Fuel outlet fittings facing rear, are white with
corrosion, as in fuel leak, as is the bottom of the cover,  bleached
like, oily and greasy.  Looks like the fiter has been leaking for quite
a while, I'd say at the copper seal,.. the fuel pumps are oily and dirty
so hard to tell if leaking there.            Early tomorrow I plan to...
disconnect battery,.. then use brake cleaner to carefully spray clean,
and wipe entire area have new copper seals for new filter, (last changed
at 81000)  any tips, or cautions, greatly appreciated,  mileage now
