How to choose

Selecting the right high pressure fuel pump for a 1.6 THP 156 HP engine requires attention to compatibility, condition, and packaging. Professionals should verify the pump’s fitment against the vehicle’s VIN or engine code before ordering.

1. Verify the engine code (e.g., EP6, 5FA) to ensure the high pressure fuel pump matches your vehicle’s injection system requirements.
2. Check the pump’s condition: remanufactured units should show no signs of internal corrosion or bearing wear before installation.
3. Prefer pumps with a core deposit system to simplify the return of the old unit and avoid additional disposal costs.
4. Select packaging that protects the pump during transit, especially if ordering in bulk for a workshop inventory.
5. Confirm the pump’s compatibility with your vehicle’s model year to avoid mismatches in fuel pressure regulation.
6. Choose suppliers with a track record of consistent quality to reduce the risk of premature failure after installation.
7. Prioritize pumps with clear documentation of remanufacturing steps to ensure traceability in case of warranty claims.

Storage & logistics

High pressure fuel pumps for 1.6 THP 156 HP engines must be stored in a dry, temperature-controlled environment to prevent seal degradation or internal corrosion. Bulk packaging should include desiccant packs to absorb moisture, and units should be stacked vertically to avoid stress on the pump housing. For workshops, a first-in-first-out rotation system ensures older stock is used before newer deliveries, maintaining optimal performance. Avoid storing pumps near solvents or fuels, as vapors can compromise rubber components over time.
