just pull the "up" valve/seal out of your regular pump.

yeah Cabrinha did the same thing years and years ago - but the adjustment knob always broke so it didnt work at all...

Just open your pump and take off the rubber bit that corresponds with the up stroke...

Cause he is a sillymanwithamoustache.

The amount of presure there is on the kite pump directly relates to the piston size, so if you cant find a pump that does what you want and dont want to modify yours then look around for the pump with the skinnyest barrel it will be easyer to pull back up. I have seen some smaller pumps at camping stores for inflating air mattresses, may be a good place to start looking.

If not you may find a nice strong lady or kid to help you out.LOL.
