when Air gets into the Fuel Injection lines between the Fuel Injection Pump and the Injectors it is hard to bleed out because the Injector is a spring loaded valve and the Aire wants to compress instead of moving past the Injector.
To bleed the Air from between the Fuel Injection Pump and the Injectors loosen the Injector nuts until fuel comes out from under them and then tighten them.

Send a pic of the Fuel Supply/Lift pump you now have on your Engine. You may be able to put a hand prime on that is already there.
(If there is a screw in Cap where the Hand Primer on the other Lift Pumps would be you can most likle add on a primer by removing the cap and replacing it with a primer.)
A way to find out is to copy the numbers that are on the little plate on the Lift Pump and take it to a Fuel Injection Shop and ask them if a Hand Primer is made it.

The Primer bulbs will last for 3-4 months and start leaking fuel and Air as they are not well made.

If you find a Hand Primer you might consider going to the Junk Yard and getting a newer style fuel filter housing as the old leaking Hand Primer will be a problem later.
