FAQ‌

Q: Is the 49040-0716 a plug-and-play replacement for 49040-0733?‌
A: Yes – Identical connectors, mounting points, and pressure specs.

Q: Can a failing fuel pump damage the engine?‌
A: Yes – Low pressure starves injectors, risking lean combustion and piston damage.

Q: How to test a fuel pump?‌
A: Use a pressure gauge on the Schrader valve (spec: 50–75 PSI KOEO).

Q: Will aftermarket pumps void my warranty?‌
A: If the failure is linked to the pump, yes. Stick with OEM for coverage.

Q: Why does my new pump whine loudly?‌
A: Aftermarket pumps often use cheaper motors – OEM ensures quiet operation.
