Cosmo 20b fuel pump and Cosmo 13b fuel pump? Same?
Just wondering if the Cosmo 13b fuel pump is the same as the 20b fuel pump? Anyone know? Thanks.

The JC 20B-REW pump will flow more than the JC 13B-REW pump.

The 20B is the orange plastic if I remember rightly.

Many FD RX-7 (92-02) guys like to use them as an easy upgrade for their hi-powered engines.
