I'd like to experiment with using a 2L coke bottle as a pressure

Nice, but I think the connections would be just too small. I want it to act
as a pressure reservoir to prevent rapid pump cycling in a motorhome pumped
water system. The exisiting system uses a pressure switch which was okay
with the old pump but a new uprated pump is causing problems and the
recommended solution it to fit a pressure accumulator

Of course I could just spend lots of dosh and buy the recommended one but
it's more fun to try and do it on the cheap. ;-)

A Coke bottle would only last a few cycles.
It's intended to be disposable.
You need a proper pressure vessel as supplied with electric undersink water heaters for example.
