The Peterson Fluid Systems rear‑drive adapter for 4‑bolt fuel pumps provides a four‑bolt interface allowing certain fuel pumps to be driven from the rear of an R4 pump. Designed to work with Peterson’s rear‑drive architecture, this adapter helps consolidate drive components and reduce overall packaging while supporting common four‑bolt pump mounting patterns in performance installations.
