I've had all sorts of fun with fuel supply, probably because my van was
allowed to sit one winter without gas in the tank and here on the Wet Coast
that is an invitation to rust.  Since then, fuel supply problems have
usually been traced to chunks of rust plugging the in-tank screen which
then results in the fuel pump being unable to draw sufficient fuel and thus
cavitating and whining loudly.

Fuel filters in either location (before or aft of the pump) do not, of
course, remedy this problem.  The only solution I've found, short of
replacing the tank, is to blow air back into the tank.  That seems to get
me another year of so of free-flowing fuel.  But along the way, I have
tried fuel filters in both the before and aft postions.  The only issue
with the before position is the difficulty in priming the pump; once primed
the pump seems to have no problem in pulling fuel through it.  I used a
smaller, generic filter rather than the larger one as shown in the pic.

Cheers, Rick
