Oil & Fuel KUBOTA B 21 FUEL INJECTOR PUMP REBUILD KIT

Clarkschapel · Dec 10, 2015

I remove the injector pump and found these numbers on it 16032 63011 96506 ZEXEL, but it has not helped me to find a rebuild kit.
Look at the attachment I believe it is a PFR type Pump inline, if anyone can help with a kit number please. Thank you Clarkschapel

I thought they were a Bosch MD type mini pump, but you should be able to get parts from a Bosch diesel repair place.
There's also a rebuild thread on one on the net somewhere I've seen.

Thanks for the responses, I decided to take the injector pump to an injector service center and have it rebuilt.
cost was about $190.00 bucks so now I have installed and Bled the fuel lines.
Engine started and did not want to shut off with ignition switch,so I shut the engine down by closing off the fuel line.
I will try again in the am to Bleed the lines again and again restart the engine, hope i can shut it off with key this time?

Check your stop solenoid electrically and mechanically for correct operation, you would have removed it.

Yeah, what he said.

Bleeding the lines won't help your problem.

There should be a stop solenoid. You had to mess with it to remove the injector pump.
