Then replace the valve "o" rings. If that doesn't work replace the valve body because the valve seat is scratched.

Try to cock the marker before airing up, and fire a couple times to reseat the seal.
What air source are you using? If i remember correctly the gti takes stright unregulated air. So make sure your co-2 tank is filled up, or the hpa tank is not a slp reg. If your frieend put a reg on the marker take it off.
Myrkul has other great points. Replace the front valve o-ring that is nearest to the cup seal. If you replaced the cup seal and did all the above (as well as clean with qtips), you may want to take a file to the valve seat and grind it flat taking out any scratches or nicks present. Ive done that to some worn nelson valves and autocockers with great results.

Umm... Not sure how to say this but the valve system is essentially the same (there are different spring combos and dimensions)as on every poppet valve gun in existence. There is nothing specific to piranha's here. Maybe if you could be a little more specific on exactly what you don't understand, we could help more.

Tippmanns and Kingman are both poppet valved. The only real difference is inline verse stack tube. Kingmans are identical to piranha, most of the parts are interchangeable. On Tippmanns the cup seal rest up against a brass plate called a valve seat inside the valve assembly. On stacked tube blow backs (STBB)the gun body contains the valve assemble, and the cup seal rest up against the valve body. Where tippmanns use a small brass plate and an "o" ring as the valve seat, STBBs just use one solid piece. STBBs are actually easier to understand because there are fewer parts. hopefully this helps.
