Hi! New guy here.

I have a New Holland LB620 with a V1902 in it (I think a replacement engine). It died on me. I figured I ran out of fuel. Filled it, cranked it, nothing. Cracked open the lines at the nozzles, nothing. Checked all lines and filters, I can blow through everything. Finally, I disconnected the return line, put a funnel in it full of fuel and it runs fine.

The manual shows a fuel pump. I don't see one on this engine. Does the injector pump suck the fuel all the way up from the tank? Is there a low and high side? I don't use the machine much. Can I (should I) save time and money by putting an electric fuel pump in it until the high side goes bad?

Thanks,
Nick

The NH LB620 normally came equipped with a 53 hp Cummins 4A2.3-C, sounds like a complicated refit would be required. ;)

If it is a Kubota V1902 in your New Holland (first one I have ever heard of)?????, there should be a lift pump on the side of the block just below the injection pump, Injection pumps can not suck fuel from a source below it.

This is the injection pump.




I don't see a fuel lift pump. I think that is a block off plate where the lift pump goes.

Thanks!
