I machined the fuel filters. The primary is like what I run on my real cars and all aluminum. (It even has the three spot welds on one end.)
The secondary is one of those glass types (that I don't use on my cars…), but I thought it would look cool on this one. I machined the glass tube from some slightly tinted acrylic rod to give the look of it being filled with fuel. The ends and filter element are aluminum and it has gaskets between the glass and metal.
