Injection pump question

[kubotakota]

Can someone tell me exactly what pumps the fuel inside the injection pump.
is it the plungers inside the barrel,, or is it the bottom round gizmo with a roller wheel attached that rides on the cam.. thanks

Plunger pump, it's the stem inside the barrel.
the roller pushes the stem up inside the barrel and the position of the stem dictates how much fuel is pushed.
Why, do you have a problem with the injection pump?

Yes very little fuel coming out.. rack was stuck and I cleaned all now rack is moving fine,, just very little fuel coming out.. is their a reasonable place to buy
injection pump parts.

thanks

That is a super easy pump to work on, only 2 replaceable parts in it, and if it's not leaking externally then it's probably just got contaminants in it and just need a through cleaning.
