One New Aftermarket Replacement Knock Out Style Tank Pressure Kit Fits John Deere Air Seeder Carts This Knock Out Style Tank Pressure Kit (A KOTPKIT100) provides all necessary hardware to route tank pressurization through the pre punched knock out holes in the top of the Fits Boss Meter Housing, delivering air pressure from the pneumatic distribution system into the product tank. This method routes pressure through the meter housing ladder rather than through the side of the tank, and is used when the Tank Style Kit (A TPKIT100) is not selected. Proper tank pressurization is critical on air seeder carts to maintain the correct pressure differential between the product tank and the primary distribution manifold, preventing pulsing or blow by during seeding operations. Compatible Models Fits John Deere Air Seeder Carts: 1900, 1910 Note: For use with Fits Boss Meter Housings only. This kit uses the knock out holes in the top of the meter housing. If using the Tank Style Pressure Kit (A TPKIT100) instead, do NOT punch out these holes seal with silicone.
