Troubleshooting & FAQ

Will this pump work with my active VRO oil injection system?

No. This is a VRO-delete style fuel pump assembly intended for engines where the oil injection system has been bypassed. You must use premixed gasoline and oil (typically at a 50:1 ratio) with this pump.

How do I know if my fuel pump is failing?

Common symptoms of a failing fuel pump include difficulty starting the engine, engine bogging down or stalling, sputtering at high speeds, a noticeable loss of power, or uneven running.

Does this part fit all V6 models listed?

This pump fits many 90° V4 and some V6 models. However, there are discrepancies across sources regarding V6 compatibility. Some V6 applications may require modification to the mounting bracket for proper alignment and fitment. Always compare the new pump to your original part before installation.

What is the main difference between OEM and this aftermarket part?

This is an aftermarket replacement part, not a genuine OEM component. It has been engineered to meet or exceed original equipment specifications for performance and fit but is offered at a more competitive price point.

What is the recommended replacement interval for a fuel pump?

There is no fixed replacement interval; fuel pumps are typically replaced only when they fail. Lifespan can be affected by fuel quality, ethanol content, and operating conditions. Regular inspection for leaks and performance issues is recommended.

What is the difference between OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.

How fast is shipping and what does it cost?

We ship worldwide quickly—typical transit is 5–15 days. Standard shipping is free; expedited options appear at checkout where available.

What is the warranty and return policy?

This part is covered by a 1-year warranty against manufacturing defects under normal use. If you encounter any issues, contact our support team with your order details. Returns are accepted within our standard window for unused items in their original condition. See our policy page or reach out for instructions.
