Is it me or is my £5 Chinese stirrup pump not working?

[look no hands]

Hi all,

I decided to try and pump my Excalibre up last night, it already had 150 psi in it, so essembled the pump as the instructions say and made sure I had PTFE white tape on all the threads, I can't hear any leaks when pumping but the gauge on the rifle just isn't moving, I must have given it about 50 pumps but no change and no air let off when either relief valve is opened or the inlet plug is pulled out.

What am I doing wrong, I've always used a bottle in the past but that was years ago and don't own one anymore.

Cheers

Pete

Maybe the £5 bit gives you a clue.

You're probably right but others have said it blew the skin off their rice pudding

I used mine to inflate my bike tubes. It definitely put air in but the gauge refused to budge.

The gauge on the pump moves but I'm not sure what it supposed to measure in? The gauge on my rifle hasn't budged, I may have to get a better whip with a gauge on it.

Funnily, I used mine last week. It definitely put air into my pcp, but the gauge was slow to move. From memory the gauge is in mpa (1mpa to 10 bar)

The pump guage is in Megapascal not BAR

200 BAR is equal to 20 Megapascal

So a shit load of pumping is needed before you see movement in that little guage, as opposed to quite a large movement scale in a BAR guage.
