I have just acquired one as part of a deal on a rifle. It appears to have a filter with silica gel crystals in each handle, is this usual ? Do they need replacing or can they be dried in the airing cupboard and reused ? The gauge is rather offset which doesn't affect performance but does rather offend my OCD is it possible to rotate it back so I am less stressed by it ?

I must say it seems like a decent pump, does anybody have any experience ?

regards
Steve
