correct flaring tool for 87 4kq

[Cade Carvell]

Hello,
  I was surfing around trying to find a flaring tool, incase I do some
damage replacing filters, etc.  Anyway, I noticed that there are several
different flavors.  Here are a few that I found:
http://www.thetoolwarehouse.net/shop/OLD-7204.html  Metric Double
Flaring Tool
http://www.mastercool.com/m53.html  Metric Double Flare or bubble
flaring tool

Which one does one use on the fuel system?  I would assume the Metric
Double Flare tool, but I am not really sure.  I like to buy tools as
much as the next guy, but I would rather not buy the wrong one, and
escpecially online.

Thanks Group,
