3" X 15" HydraMat®, Rectangle (16-111)
Holley's latest Hydramat design has an 11mm outlet that connects to the TI 450LPH and other pumps that use the same attachment design. The outlet has 6 lock pin positions to allow you to index the Hydramat on the fuel pump for custom applications depending on your fuel tank or cell setup.
The multiple pin locking feature on the pump inlet allows for removal and repositioning without damage or loss of retention. This is a huge advantage over the "one use only" filter socks that are included with most pumps
