Emma ★★★★★

Dropped the assembly in over the weekend and the PTFE return lines routed perfectly without kinking. The pump fired right up and held pressure steady during a quick street pull, which is exactly what I needed before tuning.

Henry ★★★★☆

Took my 9th gen Civic Si from stock fueling to E85-ready in about two hours. The stainless-steel PTFE lines in the return kit feel much more durable than the rubber ones it replaced. Only wish the kit included a wiring diagram for the fuel pump connector.

Michael ★★★★☆

The stainless‑steel PTFE lines were noticeably stiffer than the rubber ones I replaced, but everything sealed up without any leaks on the first try. Took about an hour to swap out in my 2014 Civic Si.
