730 diesel fuel system

[krissy]

i have a 730 diesel i cant get fuel in pump. tractor has good compression, but sat a few years.
i recently had the injector pump & injectors gone through at a diesel shop. rebuilt the fuel pump on end of governor housing. when putting the pump back on, i had fuel at the block where it enters the pump.
tractor will not start, no smoke. i pulled off the fuel line on the side of the block, & it flows good. the return fitting on top of the pump is dry? thanks

Unless the tractor is running or the tank is more than 1/3 full the fuel will not run out the top of the rack at that large hex fitting. It has a straw on it that sticks up in the tank for return.

If you bleed at the filters it should start back up unless you have other issues.

Sounds like you still have air in the system. Diesel being a fluid does not compress therefore it moves through the closed system. Air however is compressable. Just a tiny bubble in that system between the low pressure pump and the injectors will stop the flow of fuel.
As stated, make sure you have more than a 1/3 tank of diesel. Check all of your connections to be sure they are tight and sealed. Follow the beeding procedure as laid out in the Service Manual.

Those systems are a plain pain in the backside to bleed. Bleed and bleed and bleed some more is the only answer. Sometimes I have seen only one little bubble of air trapped in one of the filters stop the fuel flow. Don't even try to start it until you get fuel at the return fitting.

If you bleed it according to the operator's manual. The engine will start on about the 2nd rotation.
