I like the idea of a plug or valve in the vent tube while underway. Are there any issues with pressurization while using the pump?
The main fill cap is not air-tight, so it lets in enough when pulling small amounts of water.
I changed the cap retainer so that it attaches to the cap via a nylon bolt through the cap, then double nutted. The bolt spins in the hole, but the double nuts hold the retainer strap. I did this primarily so it would provide and additional bit of an air inlet into the tank while the ventline was plugged yet would not allow much water to slosh out. It seeps a bit, but that's ok.
