I bought this hose to use with a Zefal Lapize pump but discovered that the connector on the pump-end of the hose is not a standard fitting - the thread is the same but the stem is much longer and has an O ring instead of a rubber washer - it never makes a seal with the pump but instead screws in beyond the depth of the thread and then keeps turning. I can't comment on its performance with a compatible pump but it is sold as a "hand pump classic hose" which it is not.
I'm sorry to read that the hose is not suited to your hand pump. please return it to us for a refund or an exchange.
