Product Overview
The pump supplies gasoline to the carburetor on supported engines. When the diaphragm or internal check valves wear, the mower may crank without filling the carburetor, run briefly and quit, lose power on hills, or require repeated priming after sitting.
John Deere’s service catalog shows UC18349 across a wide range of lawn-and-garden equipment, which makes the part number a stronger identifier than model-family wording alone. Engine-specific pulse/vacuum plumbing should still be checked during diagnosis.

Before You Order
Match UC18349 or the superseded number from the original Deere parts diagram and compare the hose-port layout. Also inspect the pulse/vacuum hose because a split hose can make a good pump appear faulty.
Frequently Asked Questions
Q: Can a fuel pump cause a mower to run only with choke?
A: Fuel starvation can contribute, but a dirty carburetor jet, air leak or restricted filter can produce similar symptoms.
Q: Is UC18349 used on more models than those in the title?
A: Yes. Deere catalogs it for additional equipment; the title focuses on the most relevant applications from this listing.
