If that's the case then your intake valve or tank is having issues or not providing enough pressure to cycle the marker.
Autozone and Advance auto both have gas tank repair kits that can be used to patch the tank.
She was with her son during his tenth birthday party, and they were disassembling the paintball markers. One child's CO2 tank wasn't inspected by the field officials, and the valve screwed off of the tank, instead of the tank coming out of the marker. This is why whenever you are unscrewing your tank, you should look to see if the valve is coming unscrewed, if so stop, do not try to fix it and get help from a field official as soon as possible.
The input valve is faulty. You have to change it.
If this is happening you are losing gas. You need to fix your hoses. Make sure you have full pressure in your tank. If the problem persists, go to a paintball pro-shop and get a technician to look at the internals.
in my case it was evaporator purge valve... valve is about $40
Take it to a paintball field and have it looked at. Or be specific about he electrical problem.
The fuel tank will need replaced. There is a vent valve made into the top of the tank that has stuck and is not repairable.
It depends what the problem is...
My Lexus dealer in Tucson AZ quoted me $712.00.
replace the seals
