I'm converting my LS1 conversion fuel tank to a drop in fuel pump module. My two stock tank fittings have been tapped to 1/4 NPT. It's hard to get a sense of the physical size of a valve on line, and how much room there really is (Of course, the valve is intended to be tucked into thee space just below the tank). So, for those that have installed a drain valve, what are your recommendations?
Thanks,
Andys
