Please help: Using Fuji Pump with Presta valve - noob thread

[jlund]

Hi guys. Sorry for such a terrible noob post. I recently switched to presta valves on my bike. I bought a Fuji Compressor Pro Pump on eBay.


The pump says that it has a "smart head" that works with both presta and schrader valves.

I can not figure out how to use the pump on the presta valves. I unscrewed the valve itself. I am having issues with the pump specifically, it worked easy enough with the schrader valves I use to use, but today was the first time I tried to inflate my bike with the presta valves.

Any advice would be greatly appreciated!

And again, sorry for such a terrible thread.

What specifically is happening? Is the pump head popping off of the presta valve when you try to inflate the tire? Or are you unable to get a tight enough seal around the valve to inflate the tire?

I am unable to get a seal to the presta valve. It works just fine on a schrader valve... I feel like I may be missing an interchangeable piece or something.

Just to make sure of the procedure you're using to eliminate the obvious stuff:

You loosen the nut on the presta valve

You push the pump head onto the presta valve

You lift the lever on the pump head to lock it onto the presta valve

Pump the tire to the desired pressure

Push the lever down on the pump head to release it

Remove the pump head from the presta valve

I'm sure you're doing all the above, but after years of providing remote tech support I've learned it's always best to be sure. /img/vbsmilies/smilies/smile.gif

If the pump head in it's locked position isn't too loose on the presta valve, you might be able to wrap some tape around the valve to get a good seal.

If the pump head in it's locked position is waaay loose on the presta valve, then tape probably won't help. It might be missing a part like you thought, or just maybe a poor design. /img/vbsmilies/smilies/frown.gif
