Kubota Injection Pump Question:

[MooShooGuru]

Working on a V2203 the injection pump shoots fuel a couple feet into the air on #2 but just spills over the port on #1,#3 and #4. Just had this pump serviced. Took a spare pump and put it on and it shoots 2 ports into the air and spills over the other two. Is this normal? The engine starts up and all, just seems to me that all 4 should be shooting fuel. Any advice would be appreciated.

the only thought I have is to place a pressure gauge on each one, and see if the pressures match within specs.

Thanks Foton, ended up taking to the injection shop, they put it on the tester and I could see all the ports were pumping just fine. It's common that all ports don't shoot up in the air.
