Ford Fuel Filters / Carb Problem
 
I like Ford engineering but they sure dropped the ball on the inline
fuel filter that takes a 15/16" wrench.

My '77 Ford pickup had a gas leak where the filter meets the carb and
in tightening the screw-in filter, the connection started spewing gas.
I had a 15/16" wrench on the filter and though the long handle gave me
way more leverage than I needed for such a small fitting, I didn't
think I was putting too much torque on the wrench because it was
turning very easily as though the filter were loose.

So... Does anyone know of any good "Indian tricks" to resolve such an
issue? I'm not sure yet if I split something on the carb or stripped
the threads but clearly, somethings going on there that's fairly
serious.

Has anyone had any success with pipe joint compounds or teflon tape on
these threads? Since it's a fuel system, I had assumed the gas might
eat right through the teflon tape.

Any help that might help me avoid replacing the carb is GREATLY
appreciated.

First off, pull the filter and see what the damage is- split housing or
stripped threads. If the threads are stripped, you can get away with
drilling it out (carefully), tapping it, and using a brass nipple, a piece
of gas line, and an after-market in-line filter. Or check into using a
helicoil in you can find one that size- I don't know if they're made for
that kind of application or not.
You can use Teflon tape- gas won't bother it at all. If you're REALLY lucky,
you only stripped the filter.

Good luck!

You need two wrenches to tighten that up. First you have to back off
the gas line fitting, then you can tighten the big one, then re-tighten
the gas line fitting.

I have seen folks split the gas line on it's seam using one wrench to
tighten the big one.

You now need to take it apart to see what's up. You can remove the
filter and epoxy the fitting in then use an inline gas filter on most of
them....

Are you sure you are not thinking about the earlier GM fuel filters? I
believe the Ford that he has simply has the fuel filter screw directly
into the base of the carb.

Ford had two or three different types of fuel filters in this era. One
screwed right into the carb, probably like what you have. Another had a
nipple screw right into the carb and the fuel filter was between two
rubber hoses. Still another (I always liked this one best) was the fuel
filter right on the bottom of the fuel pump. If you stripped the
threads in the carb, you might try to JB Weld a nipple into the carb
and have your fuel filter elsewhere. For peace of mind, I'd probably
get a different carb with good threads. This is with the assumption
that the carb threads are ruined. Like another poster stated, maybe
it's just your fuel filter threads, but the way it was designed the
filter threads usually never get stripped.

You are probably right.

Whatever you decide to do, keep in mind that the integrity of the connection
must not be in doubt. I'm sure you can imagine what would happen if it fails
and raw gasoline begins to spew all over a hot, running engine.
