Just did the R & R on the top middle seals and the head seal for the injection pump. My QA needed replacement, so i did the rest.
Ok I've read a bunch of threads on IP priming.
Attach the mityvac to the fuel return line that is coming from the top of the injection pump going into the ThermoTee on the fuel filter.
Cover the end of the end of the thermo tee that is now exposed.
All fuel lines are attached and on tight.
Pump the mityvac to keep vacuum, bringin fuel from the filter/tank into the pump and then into the clear line attached to your mity vac.
Now how long are you guys all pumping this freakin thing??? I was going 5 minutes, and MY ARMS ARE SO TIRED. left hand, switch, right. switch left. switch to double arm sqeezing, move to one hand with the other assisting. 10 minutes I heard from some of the posts...
How do you guys keep that vacuum up? I'm getting it up to 20psi but usually 15 psi. It drops slowly, about 5 psi every 2 seconds. Does that mean I have a leak somewhere? Does the fuel filter being "open" matter when I'm priming?
I checked the seals again, and the head seal was in place, the top and QA were fine. So I thought readjusting would be good. Still can't get that vacuum to pull the fuel hard enough. I can get a bit to move in the clear line, but I can't get it into the pump!!! ARGH
Wish I had a way to push the fuel into the pump, but no electric pump.
Lastly, having the pump not totally filled with fuel for a long period of time, is that bad? I mean it's glistening with fuel, but it's still not primed.
Thanks. Jeremy
