The ticking noise was one reason I didn't want a diesel heater a few years ago when I was looking for a way to heat the inside of the vehicle (I sleep there instead of in a RTT). But this year, I found out about a silent fuel pump invented by a guy named James Browning-Smith. Apparently it uses a different mechanism altogether to pump the fuel. 8:20 of the YouTube video "Quiet diesel heater pump. Invented and built by a British enthusiast." shows the pump really is silent.
The 5.5 liter plastic fuel tank I got has a little hole in the cap which lets diesel fumes out. Smelling diesel fumes when the heater is running would be a dealbreaker for me. So I'm thinking of using a beefier gas can, like the No-Spill 2.5 gallon gas can, which doesn't have a vent that is permanently open. Then, to let it breathe, I would install a two-way breather valve to relieve pressure inside when driving up mountains, but also act as a vacuum valve and let air in while the heater is running. Maybe this would get rid of the diesel smell during heater operation.
