S13

Stock S13 240sx/200sx fuel pump can support up to 220hp on gasoline, probably less due to it’s age.

Direct replacements like walbro/dw 255 are the most popular, but pump needs to have inlet/outlet ports on same orientation for best fitment.

Walbro lists GSS341 as a direct replacement in their catalogs, but GSS342 fits better (400-766 install kit)
Deatschwerks DW200 9-201-0766 has ports on same orientation
