Product Overview
Hard starting, stalling, weak acceleration, or a pump that no longer primes can send diagnosis toward the in-tank module. This assembly combines the pump and related module parts for vehicles using the 31110-D5500 design.
These cars can also have high-pressure fuel-pump, relay, wiring, sensor, or engine-control problems. Verify low-side pressure and match the VIN, engine, connector, tank opening, and original number before ordering.
This is an aftermarket replacement part and is not manufactured or supplied by the original equipment brand.

Compatibility Notice

Compare the original component, reference number, connector or mounting design, dimensions, and any serial-number or production-date break before purchase.
Frequently Asked Questions
Q: Is this the high-pressure pump on the engine? A: No. This is the in-tank low-pressure fuel pump module.
Q: Will it fit every 2019 Optima? A: No. Engine, VIN, emissions package, and original module number must match.
Q: Can a weak pump cause hesitation under load? A: Yes, but pressure testing should separate a low-side pump problem from ignition, injector, or high-pressure fuel faults.
