fuel tank questions

So a new spectra premium tank (non vented) and sending unit it will be. And a non vented cap as well. I unfortunately through my original sender away including the lock ring. UGH
Thank you all very much for your advise! Much appreciated
If you're going to use an aftermarket sending unit and lock ring be sure to check for leaks before installing the tank into the car. Also you'll want to look through the filler neck hole after installing the sending unit to be sure the pickup tube reaches all the way to the bottom.

Don't forget a filler neck grommet and a tank pad
