hello again, fyi hand pump in question is a galley, self-priming pump.

if you havent used it for a longtime it may have dried out inside there is a seal that sucks up the air and water, it it drys out after use ( 1 year + ) it shrinks to flx it get a bottle cut a small hole in the lid put in a straw and squirt water back into the tap end till its full of water then try it again,
this may take several goes to resoak the seal

thank you. your advice was spot on. much appreciated.

If sptpc's suggestion doesn't get it going, it may need a rebuild (or replacement). Perhaps something could be stuck in the pump valves, so that may make taking it apart worth the effort.
