Just received a gas tank for the GTX from Amazon (I know, but it is a Spectra brand tank cheaper than anywhere else due to the free shipping) and inside the box was also a new sending unit. The packing list showed new tank straps (which weren't in the box), the tank and the fuel sending unit. I checked Amazon, and there is no mention of the fuel sending unit or tank straps being included with the tank. I am thinking that I should reach out to the seller and let them know they made a mistake. I suspect that the sending unit won't be correct for the car as I ordered a Roadrunner tank, not one for a GTX as they didn't have any in stock (funny as it is the same p/n and tank). So I think that the line size may be small; 383 vs 440.

Tanks should be the same size I think 19 gallons. The senders may be different between the 383 and 440 I think the pipe can be either 5/16 or 3/8 depending on the sender and car. Don't quote me on that, more people with more knowledge will chime in.

I looked up the tank for my GTX out of a curiosity. Turned out it was the same across the board for that body style. Obviously the RR and GTX and Satty for that matter are all the same body style. Couldn’t tell you about the sending unit.
