wrong pump?

So I bought this pump, Remote Plunger Pump by Doc Johnson, and the dimentions are 8” circumference x 8” Length.

I myself am 6.4 EL x 5.6 EG. I’m taking it I bought the wrong pump. Didn’t order it online or fit the tube, never knew about fitting the tube.

Did i just waste my money or can I still get by with this pump?

Probably not. It doesn’t have a gauge so you have no idea how much vacuum is being applied to your dick. Plus the tube has a 2 3/4” diameter which is way more than you need for your current girth. Getting a quality cylinder and hand pump with a gauge will run you about US $130. Have you read Pumping 101?

I read pumping 101 after I bought the pump. I was looking at a Dr. Joels Pump but that was over $200 at the store.

Well there’s no way I can get a quality pump for a bit so i wonder how I can get away with this one for now.

Maybe if I pump the trigger fully two times, I get a moderate suction and I could go 8 mins sessions.
