Reply to "Fuel Sending Unit & Fuel Filler Hose"

FWIW, Khan, once the rear quarter window is out, you can push the glass out of the gasket, then replace the chrome-trimmed frame back into the car. The missing glass does nothing to the aerodynamics of the car as the boundary layer doesn't notice there's no glass- just like the Maserati Merak. And it makes servicing the fuel tank top and cleaning the back window much easier, plus dropping around 6 lbs of weight. Both windows come out identically- push only. An occasional Pantera will have the metal 'gill' overhang the rubber gasket so that gill might need to be loosened or removed.
You'll likely find that the tank fitting and the outside gas filler spout on your '74 are horribly misaligned. There is no easy way to R & R this short little hose but be very sure the replacement hose is marked "For Fuel Use" or you'll be smelling gas in the cockpit within a year. I pull the outside spout out a ways through the door grommet to get the new hose on the tank, then push the spout back into the open end, with a little WD-40 on the hose to ease things along. It's just a wrestling match. I wouldn't use clear racing hose unless you cut a short piece off and soak it in gas for a month with zero damage resulting. Oxygenated gas sold these days attacks EVERYTHING plastic, and racing stuff is not normally used long-term. The connecting hose nearly always cracks underneath so you cannot see the problem.
