Sounds
like the same problem I'm having w/my F.
Only it usually rears it's ugly head
under high temp conditions.
I took it out last week one day and rung it out
pretty good, temps were in the high 60's, w/no stumble or acceleration problems
at all.
Same car, temps in the 80's and 90's like we were experiencing at
Mcungie, car runs like crap after the 1st 5 miles or so, when it gets warmed
up.

That really makes a lot of sense
to me, Don—great input ; not enough fuel moved. And clean inlet
stuff.

I had the same problem with
my RAM K a few years ago and what I did was get a high volume mechanical pump
from Summit. Problem went away.

I will check the fuel pressure numbers again, I am working off
of the mechanic’s notes. We will talk another shot at this and try these new
ideas and will post again.
The car shows 65,000 but we do not know if
original and how many since rebuild.
Thanks, Mark

That fuel pressure is way too high. Did you replace the
accelerator pump on the carb, some kits don't include them. You must be getting
a good shot of fuel as the throttle is opened. Dried, flawed, dirty, or
improperly adjusted pump plungers can cause starvation on hard acceleration and
not provide enough fuel at startup.
Are you confident your ignition
system is sound? How many miles on the rebuild?
Just in case you needed

Isn’t it about 5-6 psi max? Cannot be right? But unrelated to

Hi Mike, the old fuel pump was tested at 10-14 psi with good
fuel flow but we replaced it because it was leaking oil next to the block and
was a inexpensive fix. Thanks Mark

Mark,
I am also interested in this issue. I am wondering
why can’t we test pump fuel delivery by pumping gasoline from the fuel pump into
a container and measure the volume over time?
Do we know how much
gasoline that pump should deliver in say, 30 seconds? I can imagine doing that
would be an easier test
Thanks, Mike Moore

First, many thanks for all
of the advice I received last week on this problem!
Okay, still having
some problems with fuel delivery on our 300K.
Here is a quick rundown on
what we have had done. Carb was cleaned and fitted with a new carb kit. Floats
were set at 23/32 spec?
Items replaced: Fuel pump, fuel pump push rod,
fuel filter and all rubber fuel lines.
Fuel tank was removed and sending
unit inspected. Blew out fuel lines.
After all of this we still are
starving for fuel when the 4barrel kicks in. Also a little harder to start and
(at times) some throttle hesitation on normal acceleration.
One question
the mechanic had was the engine rebuilt with bored cylinders etc and needs a
higher CFM carb. I do not have any history on the engine other then it has been
rebuilt.
Any help will be much appreciated! Mark

Let's assume the problem is not
with the carb.
There are 3 pieces of "rubber" fuel line in the
system.
If they are old, they need to be replaced to
ensure you
aren't drawing air into the system through an
age crack in the old hose,
or perhaps a blockage in the hose.
One is at the fuel tank, connects the
sender to the pipe.
One is in the area of the front passenger foot well,
connects
the pipe to the next pipe.
The other is from that pipe to
the fuel pump inlet.
It is a pretty easy job to replace these pieces
with new line.
I think the diameter is 5/16".
It could be the
problem is with the fuel sock on the sending unit. If
the tank has rust
in it, the sock will plug. While it isn't a terrible job to
get the
sending unit out, it takes a while.
If you suspect the sock, but would
rather not get into the sending unit,
you could try running the car from
an aux fuel tank. Run a long
piece of fuel hose from the fuel pump inlet
to an aux tank which
you could place in the pass front seat. Have someone
hold the aux tank
so you don't get spills. If the carb performs off the
aux tank system, you
know where your fuel restriction is (or
isn't).

Mark,
If I had to
guess, and based on past experience, I’d say your fuel pump push rod is worn,
and can’t push the fuel pump arm enough to feed ample gas to the carb. Ask me
how I know this.
Happy Moparing,
Mark

Problems
Hi, I have a new to me 1964 300K with the single Carter 3614S 4
barrel carb. The carb is starving for fuel when I kick in the seconda ry. I just
had the fuel system checked out and there are no kinks, fuel filter is new, fuel
pump has good pressure and had the carb rebuilt with a new kit and the carb
tests fine. The secondary kicks in but the car surges as it starves for fuel.
Under brisk but normal acceleration the engine runs fine. Any suggestions would
be much appreciated! Thanks Mark
