http://67-72chevytrucks.com/vboard/s...d.php?t=621177 I started this thread a while ago and it wraps up with me installing the tank you are asking about. I covered my filler cap install in there too. (Yep, cut bedstrip, but not like you think) Tank still works great today, but the universal sender is a bit "off". It stays on full for a little too long and then I run out of gas at 1/8 of a tank remaining on the guage. Now I know, so I fill up when it hits 1/4. (Probably could be adjusted but I'd have to raise the bed to do it.) Edit: I never told where my check valve breather/vent is... I ran it up the rear passenger's side stake pocket. It does give off a few fumes when you're standing there on a hot day, but it is a good spot to stash it up nice and high.
