Neck Fills

Never underestimate the need for neck fills.  In my case, I need four of them....two water tank neck fills and two diesel tank neck fills.

I  used a table saw with a carbide tip blade to cut  off short sections of aluminum pipe.  

I then cut grooves in them to help provide a secure fit to the connection hoses.  Two of these pipes will be welded to an aluminum flange and these will become neck fills for my water tanks.  The other two will be TIG welded onto the diesel tanks.
