Ford 6600 injector pump

On the Simms inline injector pump there are 2 Bango bolts. They are both 5/16. One is located near the top front of the pump which has lines connected to it that go to the injectors and the fuel tank.
The other one is located on the back of the pump and has a line connected that hss a loop in it and goes thru a bracket at the oil pan. This seems to be a vent for the oil resevoir for the pump cam shaft. Are these Banjo bolts identical? They have a very small hole in the sides but one seems plugged up. Any help would be appeciated.
 
The bolts will interchange, but if there is a bleed orifice size difference use the small one at the fuel block. The cam box bleed vent is not as critical as the fuel block bleed is. If the fuel block bleed bolt hole is too large it will drop the fuel feed pressure to keep the plunger barrels filled during the charging cycle. Early Ford Simms pumps did not use the bleed orifice, but if a gulp of air entered the block the front two or three cylinders COULD start missing until the bleed bolt was loosened to get the air out. That problem went away on later tractors with the constant bleed orifice line was added.
