Allis Chalmers 5020 questions

i just bought a 5020 not to familiar with this one. im trying to find a couple things i need to replace on this tractor with no luck. i need to find new head lights for them the wiring is there but no bulbs or the glass where could i find these and what all would i need. Also trying to find a new steering wheel I can find every other AC steering wheel but not one for this 5020.

Also this tractor had sat for three years when i purchased it. Ive cleaned the fuel tank out and flushed the lines with good fuel. i was getting fuel to the injectors but it stopped and I cant seem to get fuel into the injectors now. I've got fuel to the injection pump with putting air to the fuel tank, but from the injection pump to the injectors I've got no fuel. I've tried bleeding the air out at the injection pump but I'm still having no luck with getting fuel. I've added oil to the injection pump because it was low. Any suggestion on what to do next? Thanks!
 
If this is a rack pump or inline the rack may be stuck. Not sure how to get it loose on that pump. If just a regular round pump like the Roosa Master then it will probably be best to see Dieseltech about getting it loose without additional cost for broken parts. Lights are probably a sealed beam bulb type light and can be used from most any 4411 number or you can cross that over to the LED lights from some place like Worthington has them the size of the 4411 that just fit in the rubber grommet holder. Otherwise I would guess you are junkyarding for them. There are several options for the lights. A picture would help a lot with what you actually have.
 
One thing you should check is the oil level for the injection pump. If it is like other Hinomoto tractors it will be separate from engine oil. Remove inspection
plate to check level. Problem with this design is it is hard to see if your rollers are making contact with the cam shaft in the event that the plungers are stuck
in the up position.
 
Forgot to mention. One way to tell if the plungers are stuck is the throttle rod inside the inspection hole won't move freely.
