DO NOT POST PICTURES OF FRESH SNOW!!! We got almost 8 feet of the nasty stuff here in Maryland last year, 5 feet of which fell in a 4 day period! That "LUMP" of snow shown in the second pic is on top of my Z, thought it would crush the suspension, 12 hours after this pic was taken it began to snow again, 2 days later there was another 31 inches of snow on top of what you see here. And to think I was afraid to leave the car in the barn for fear of collaps. In these two storms I measured a total of 58 inches in my driveway. No where to put the stuff after a while. It really sucked.
By the way, The flat tops are trash, even without the duct tape, get rid of em.
Also, looking at the condition of your hoses, you had better check out the vapor lines in the back of the car. What I see there is almost exactly like what mine looked like when I got it last year. (73 240Z) The second time I filled her up the left side balancing hose just fell apart at the pump and dumped like 4 gallons on the gas station lot, not a goot feeling. There is a 1/2",5/8" and 3/4" line inside the cockpit that I will bet have never been touched. you need to check them out!
