My '65 coupe, 289 2v, has been acting like the fuel filter is
clogged. Acceleration is no problem, but at a steady speed I
get a hesitation every once in a while. It feels almost like I've
let off on the accelerator.

Anyway, I was looking around for the fuel filter this weekend
and couldn't find one! The metal fuel line runs from the carb
down to near the wheel well where there is (if memory serves
me) a short rubber line going to more metal that goes through
the inner fender.

Am I looking in the wrong place or was a fuel filter just an
option? If I install one, where should it go? Do I cut the
metal fuel line and just patch it in near the carb?

Thanks for all the help!

On my '70 the fuel filter screws right into the carb where. I had similar
problems and got a $14 overhaul kit (new gaskets and needle valve), it did
a great job. Also B-12 Chemtool is real good for cleaning carbs. Fill your
fuel bowls with it and let it soak over night.
I had a truck with sticking floats, this caused the gas to overflow onto
the manifold... Anyways after letting it soak overnight, no problems...

There is also a "screen"/filter on the fuel sender unit
in the gas tank. I'd start with the filter on
the carb, and if you still have problems you might
want to look at the one in the tank.

If you have consistent problems, it could be a
rusty gas tank and/or dirty gas.

I spent a long time troubleshooting a fuel
related problem on my 65 falcon recently.
I think the problem was due primarily
to rust in the tank and fuel lines.
But the problem was much reduced,
but still persisted even after "repairing" the
tank and replacing the lines and filter. I swapped
the carb with another I had around, and now the
problem is gone. I have not yet rebuilt the old
carb...but I suspect the rust/dirt had clogged
something... (stock 2bbl autolite carb).

Good luck...

For those who are or have experienced random stumbling while cruising
at steady state, here's something easy for you to check; vacuum leaks.
On two of my Mustangs, the same vacuum leak had me replacing parts for
days. In both cases, it was at the grommet sealing the vacuum hose
to the brake booster. The booster can is sheet metal, and the hole
that the grommet sits in has sharp edges that will eventually cut the
grommet at a place that you can't see. In my case, the second one
followed the first by about a year, and I didn't think it could be the
same problem so I didn't check it until much later. In the process, I
replaced (between the two of them) two fuel filters, two sets of plug
wires, a distributor, points, rotors, spark plugs, and rebuilt both
carbs.

Other more obivous places for vacuum leaks are in the PCV hoses, or on
the vacuum tree on the manifold.

good luck

Dean,

On a stock 65, the fuel filter hung from the bottom of the fuel pump. The
pump is at the lower driver's side of the timing cover on the front of the
engine. The fuel pump has a screw-off cannister (looks like a mini-oil
filter). The filter is inside.

Good Luck,
Ron Columbo
