The Details

The Nissan seats are for top feed conversion rails, which is what makes a side feed engine accept top feed injectors. They are sold individually, so order one per injector. The 30mm seats are black anodized and the 25mm are Radium green, both CNC machined with a common 14mm bore for the lower injector O-ring.

The 20-1044 Mazda seat is the 16mm primary, matching the primary injector position on rotary applications.

Gaskets are service items: replace rather than reuse whenever the joint is opened, since a compressed gasket will not seal the same way twice.
