So I lifted the air cleaner from the engine and I found a broken rubber thingie, I think it is the acc_pump.
I am wondering can I get the rubber boot as a seperate part somewhere? and can it be replaced whith carb still in car?
I know the rubber part is included in a complete carb overhauling kit, but I do not want to completly redo the carb at this time as it is driving season.
Other than this the air filter must have been in the car for ages so that is up for replacement asap.

Re: 65 carb problem
It's difficult for me to say what carb, but it's in the right position on the carb if it's a Qjet. However, don't just replace the external rubber boot. Today's fuels are more than likely to contain ethanol and the factory 1965 rubber piston seal inside the plunger doesn't like ethanol. It deteriorates quickly when exposed to ethanol, so you should buy a modern accelerator pump which is resistant to ethanol. Cliff's Performance and some others sell these, so I would advise you to do your research before the accelerator pump fails and leaves you stranded somewhere.
That area looks like it is wet with fuel, if it's leaking I wouldn't want to drive it in case of fire. Better to be safe and get it fixed, and yes the top has to come off. If you do it be careful of the metering rods, they can't be bent. Depending on your carbs condition, I probably would get it redone with the top off not farther to go.
As aussiejohn said do some research, the qjet aren't as simple edelbrocks or holleys.
I have companies that will supply a repairkit for the carb,
are they all now containing the new type of seals for the acc-pump or is that something I need to get extra?
if/when I lift the top of the carb is there something else that I should replace?
