This kit upgrades your pump marker for higher flow to speed up target drawing, reduce nib wear, reduce time to refill the marker, and reduce marker component expsure to air to reduce ink clogging and congealing for smoother operation.
This kit includes a custom valve plug and a funnel that can be used to refill the marker once the marker has been upgraded.
*Note - This kit is made specifically for the WATL brand marker. It will not work on another model.
