Bob:
I hadn't thought about rust inside the hard lne, after the filter. Quite possible, as the car sat for a number of years before we hauled it out of the barn and started working on it.
Thanks, I'll definitely take a look-see inside the line.

: Jim,
:
: Do you have any idea what is causing
: the blockage? Sometimes if a car
: sits around for a long time, all of
: the gas drains back to the fuel
: pump, the fuel line will be opened
: to the atmosphere via the empty
: float bowl and open needle, and then
: the fuel line will rust inside. Then
: the rust can break loose and stick
: in the needle. I think that the fuel
: will drain back fairly rapidly. If
: you shut off the engine and
: immediately disconnect the fuel
: line, it will spray gas all over the
: place. However, if you shut off the
: engine and wait for an hour or so,
: you will find that the line will not
: have gas in it and it will not spray
: fuel. If there is rust in the fuel
: line, every time you start the motor
: after it has set for a while, the
: gas will surge through the line to
: the carb and if there are any loose
: particles, they can break loose. You
: can see if this is a problem by
: looking at the bottom of the float
: bowl and see if there is a layer of
: "brown mud" on it. This is
: rust that consists of fine particles
: that have flowed past the needle and
: settled on the bottom of the bowl.
:
: In order to fix this, you might try
: replacing the line from the fuel
: pump to the carburetor. Or you might
: try installing a filter at the
: carburetor inlet (if you can find
: one that would work). However, you'd
: have to cut the fuel line to do
: this.

: Well, I had to go "rescue"
: Amelia for the 2nd time late last
: week. A tiny piece of debris got
: between the needle and the seat of
: the carb causing the bowl to fill up
: and overflow.

: Car is a '63 Falcon, 170, with a new
: rebuilt fuel pump (from Advance
: Auto). Carb is (I think) an 1100,
: rebuilt by Holley and purchased at
: Auto Zone. You can see pictures of
: the carb and fuel pump here

: You will need to wait for the
: slideshow to get to the engine
: (sorry!). The greasy red engine has
: the carb and fuel pump in question.
: There's no air cleaner in place so
: you can see the carb.
:
: Wishing not to be stranded for this
: same reason yet again, we got
: serious last Sunday. We inspected
: the built-in fuel filter (the one
: that's mounted inside the fuel pump)
: and found that it was a folded-paper
: filer - just as you'd expect.
:
: So, I added an inline fuel filter
: under the car at the fuel tank. I
: realize that mounting the filter on
: the suction side of the fuel pump
: isn't the ideal way to go, but I'm
: hoping this is temporary, and I
: didn't want to butcher our underhood
: hard fuel line.
:
: My thinking is this: zillions of
: these cars ran just fine for years
: with nothing but a built-in fuel
: filter. I shouldn't need to add
: anythything. Is there a known issue
: with some of the built-in fuel
: filters being junk and others being
: good? Is there a magic "high
: quality" fuel filter out there
: somewhere that all you Falcon gurus
: discovered years ago? Am I being
: unrealistic in my expectation that
: we should be able to drive this car
: for more than a week without the
: carb gushing like a courthouse
: fountain?
:
: Please share any pertinent
: experience.
:
: Thanks in advance,
