FFD Cylinder Fluid Evacuator SKU: ffd141

I purchased this trying not to have to set valve covers back on with glow plugs out turning the engine over to clear out the cylinders. I tried it with injector cups in on 2001 7.3 the hoses are to big for the whole but once cups are removed it will fit I was hoping it would go through the cups so could use it more often than just changing cups but still be useful for other projects I’m sure
