The tube can be cut with no issues. As it will sit in the bottom of the tank surrounded with fuel that will eliminate oxygen and without oxygen it wont corrode. I cut Fuel lines every day with absolutely no issues. When we pipe a car for fuel brakes or any other system that requires custom line cutting is a fact of life. Other than E85 which is very corrosive you will not have any issues cutting . Or just a thought?? Can you bend it to fit?? Not the float the tubing. Without seeing it it is hard for me to vision the issue. Thanks Tom
Note another option!!!!
Remove the IN TANK filter. SOCK from the new sender. This should get you the room you need i think. Then install a 100 Micron filter in the line between the pump and the sender. I do this all the time and it works great. With this setup you can service the suction side filter without dropping the tank. Be worned you must not use a finer filter than 100 Microns. If you do the pump will starve for fuel Good luck!!
NOTE keep the pickup off the bottom of the tank by at least 1"
