Material: 356 T-6 aluminum. Process: Lost foam. Weight: 17.7 lbs. Dimensions: 10.5 x 7.5 x 10.5 in. Application: Heavy truck fuel fi lter.
• A complex coring design produced seven independent passages that had to be tight to 2.5 cu. cm per minute at 6 bar units of pressure. T e original design was simpler, but lost foam allowed the more complex coring to produce a better fuel route through the fi ltra- tion system.
• As the initial design evolved, numerous features and passages were added to enhance the fi nal product. T e lost foam process allowed the design fl exibility needed to consider and implement these iterations.
