After rebuilding the carb its going to sit for a few months befor being put into service, is there a concern for the rubber on the pump drying out or do you need to lube it with something?
-
Keep it in a dry area & rap it up in some plastic
bags, I think the rubber will be fine though Im no chemist
those gaskets sit around before installation for a long time any ways
and are fine.

I'll assume that those new accel pumps that Cliff sells would probably not be affected too much. If the alchohol (in the gasoline nowadays) dont dry them up, I guess sitting around for a few months wouldnt hurt them. (im jus guessin here??)
That actually is a good question; if you were building a carb and you knew it had to sit for a year (lets say) what do you do, coat the inside with some kond of spray? how about vasoline or something similar?

As far as I under stand rubber and plastics its air
moister & light you must protect them from.
There are many products available to protect rubber
from cracking drying out and UV damage, but they are designed for dash boards
or for tires, I dont know of any product designed for gaskets.

The pumps that we use have a high grade fouroelostomer seal on them, they are uneffected by drying up, or exposure to any modern fuels, including E-85.
Same deal with the needle/seat assemblies.
The gaskets are the higher quality "non-stick" and "non-shrink" variety.
Don't be fooled by any "blue" seals you might find in any over the counter kit. They are NOT the same as the ones we use, and they will swell up when exposed to ethanol or alcohol......Cliff

Good to know. I wasnt sure about the new pumps, Ive never let a carb sit after built. Its gotta sit til the weather warms ( still bouncing from 20 to 40 degrees ) and I can get out to pull the engine down for some rework. no heater in the garage.
