i picked up one of these http://www.vandenbergsurf.com/media/...mp_bp_12_1.jpg
for a few dollars just because it was the only thing available and it worked! got home and ataached it to the guage and the tube was very soft so it was reading 0 psi pretty much. i have an Avon version of this http://www.defender.com/images/450566.jpg
and the gauge on the pump next to the top middle port says 3.5psi, while the port itself says+2.1psi. i started pumping away with the lower pressure port and it got pretty hard to pump after a few tries which i assume means the ports pressure limit had been reached. the ports says 2.1 psi but my guage wasnt reading that. i switched to the high pressure port and eventually got the needle on my new gauge to start moving. i stopped at 3psi because the boat was harder than i'd ever felt it and i started to worry about bursting. pumping never got very hard though. mind you i've only had it for a few months but it always seemed pretty firm in that time. the guage on the pump never got to the red zone to indicate i'd gotten to 3.5 psi either so i can only assume that they are both working correctly. thoughts on that anybody?
after proving i could get air into it, i deflated quite a bit because i inflated it when the temp had dropped and by the time the sun hits it tomorrow it will have firmed up significantly
