Does anyone have any tips for replacing the molded hose for the water flush inside the cowling? I installed the lower opening first (connects to adapter out of cowling) but am having trouble sliding the upper part onto the coupling. Hard to get leverage in that area. Thinking of redoing it and installing the top part of the hose then lower. Did dab a bit of grease on the top, just can't get leverage.<br /><br />Thank you!
