This is the genuine Kubota fuel pump gasket, part number 16261-52140. It seals the mechanical fuel lift pump where it bolts to the engine. Kubota’s parts book for the D1105-E3B lists it with lift pump 16285-52033, and with the older 16285-52032, from engine serial 8J0001 on. Kubota’s parts book for the V3300-E4BG lists it with lift pump 1C010-52035.
Fit a new gasket every time the lift pump comes off. Kubota lists the gasket as its own line, apart from the pump, so order one with the pump.
Confirm Fitment Before You Order
Kubota changed this gasket by engine serial number. On the D1105-E3B, engines up to serial 8HZ999 take 16264-52140 and engines from serial 8J0001 take this one. For any other engine, send us the engine model and serial number and we will read the gasket off the Kubota parts list. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.

Frequently Asked Questions
Which gasket does my D1105 lift pump take, 16261-52140 or 16264-52140?
Kubota’s D1105-E3B parts book splits them by engine serial number: 16264-52140 up to serial 8HZ999 and 16261-52140 from serial 8J0001. Call 530-668-0818 with your serial number and we will confirm it.
Does a new lift pump come with this gasket?
Kubota’s parts books list the gasket as a separate line from the pump, so order one with the pump.
How many gaskets do I need?

Is 16261-52140 used anywhere else on the engine?
Yes. On engines built without a mechanical lift pump, Kubota fits a cover over the pump opening. Kubota’s parts book for the V3800DI-T-E3B lists this gasket under that cover from engine serial 9A0001.
