Upgrading generic pump with hand gauge?

Can I upgrade a generic pump with hand gauge? Is the valve compatible? In the attachment you can see what I mean if it’s not already clear. Wanted to buy a cheap pump with built-in gauge but I think this would be a better solution.

I will buy the cylinder separately later on. It’s just for testing now and cheaper for same pump.

If that is the cylinder you are using you can probably find a way to connect with that pump without using quick disconnect fittings. Neither your cylinder or that pump has quick disconnects.

Didn’t think about quick disconnect. Thank you for pointing this out. Where does LeLuv’s pump have the quick disconnect or is on their cylinder? Both pumps look identical. At least for me.

Can’t the cup act as quick disconnect too? I’m not a physicist but can’t you just unscrew the cup or pull out the tube for same effect?

Scroll down a bit on this page to see what the male and female quick disconnects look like. The male attaches to the tube and the female screws into the top of the cylinder: https://www.ama … /dp/B00EJRKLGI/

The cylinder you show does not have a female fitting and that pump in the red box does not have a male fitting.

So, basically you want to use the cheap cylinder with the upgraded HF/LAPump-style pump?

It looks like the cheap hand bulb pump is attached to the cylinder with a barb on top of the cylinder, and it appears to be larger than the hose that would come with the HF/LAPump-style pump.

So, you could do it; it would simply require a short section of larger diameter tube that you would install on top of the cylinder on the barb, and then, using the adapters that come with the HF/LAPump-style pump, you should be able to connect directly between your small section of larger tube and the tube that comes with the HF/LAPump-style pump.
