I'm having issues with my car stalling at speeds over
70 mph. This has been a long-term problem that has
kind of come and gone over the last two years, but
always come back. Since the problem started, the motor
has been rebuilt, I've swapped intake manifolds and
carbs, put on an entirely new exhaust system, changed
and tweaked the timing numerous times and changed out
the fuel pump. Yet, the problem remains.

I seem to get temporary relief by swapping out the
fuel filters on a regular basis. However, the filters
are by no means what you'd call clogged and this last
time I even purchased the clear plastic filter to see
if I could find any crud in it, but haven't despite
the fact that the stalling problem has come back.

My last thought is that perhaps I have some crud in
the gas tank that just floats around until the car is
really sucking gas and at that point it clogs the
sender. The obvious way to check this is to drain the
tank, hammer out the lock ring, check the sender, then
put it all back together. Anyone got some other
ingenious (zero-effort) method they've used
to check for crud in the tank? I'm thinking about
lashing a small fish tank net to a coat hanger and
just running it down the filler tube to see if it nets
any crud. I know, I'm lazy, but I just figured I'd see
if anyone else had a tried and true method before I
started expending energy on this.

I had a similar problem with my 66 Mustang.
I had a multitude of problems.
The gas line was clogged and would stall after I drove a period of time
(sometimes leaving a stop light) and would "clear up" after I sat for a
while - tried the filters, wound up changing the fuel line.
The second problem was it would stall over 65 only to run good after I
slowed down below 50. Turned out I had a 351 fuel pump in my 289. Got the
right pump, problem solved. Learned about knowing which pump is which from
Mustang Monthly years ago.
Hope this helps.

Scott
71 Mustang
