I bought a 445A with a injector pump problem. CAV-DPA pump. There’s no fuel exiting the pump head. Upon further exam, the engine was replaced with a late edition BSD 333 (New Holland logo cast into the block.). The prior owner’s mechanic took the cover off the top of the pump. I have no idea what he did other than as stated below. The fuel tank is covered with a layer of rust, all the way to the fuel cap. The PO drained some or all of the fuel, installed a new Napa fuel filter, added Seafoam to the fuel and directly to the injector pump after removing the cap. I can crank the engine and get fuel to spurt out the bleed screw on the side of the pump (transfer pump is working???) but there’s no fuel exiting the pump head at the injector lines. The metering valve moves freely and the shut off lever is indexed properly with the shutoff shaft. My guess, from seeing a little discoloration on the shut off lever, is there was water inside the pump. I could remove the metering valve and see if there’s crud blocking the fuel passage but I don’t see a lot of other options besides tearing down the pump. I’d appreciate any suggestions offered.
