Datsun 240Z Restoration:
Fuel System, Part I
Made a bit of progress last night. After draining 2-3 gallons of 8-year-old gasoline-turned-varnish (below), I removed the fuel tank (above) without too much drama. All three of the evaporative emissions system hoses that intersected the tank were completely shot, so they were snipped (along with a fuel line), but I’ll be replacing all the rubber anyway, so it wasn’t critical. Other than that, all the bolts and screws turned remarkably readily for the first time in 40 years, even exposed as they’d been at the rear of the car. A little shot of PB and everything was peachy.
Needless to say, the garage reeks of old gas now. I’ll probably mix this in with 2-3 gallons of fresh gas and feed it to my lawnmower. The consensus seems to be that it’ll be fine.
The really great news was on the inside of the rear quarter panel, shown above. Yes folks, it’s all solid metal. There’s a bit of superficial rust here and there, but based on my cursory inspection, no actual rot. If the car’s structural rust is confined to the passenger side floor pan and rocker panel, I’ll be a happy (relatively-speaking) man.
Given the good condition of the inside of the tank, the question at this point becomes: Should I use the POR-15 Fuel Tank Repair Kit, or just clean and seal the outside of the tank and call it a day? I’ve used the POR-15 kit before (on my old Audi 4000’s tank) with good success, so that’s charted territory. But I’d rather not do more work than I really have to. Hmm.
