New Used TD IP, advice & input needed, reseal LDA? & part# help.

It was some what primed when I did it, i got a 2-3 inch long air bubble just below the bottle then I rigged it up, thats how I could see just a small trickle.
The return went back to the tank.

New Update:

Found the Vacuum leak. it's the throttle shaft bushing or seal, and it's huge!  If it was rebuilt it was a crappy job. I couldn't narrow it down because it was so big I couldn't get it to hold a large enough vacuum long enough to find the leak. Instead I used a small bike tire pump and some soapy water to look for bubbles and that's how I found it.

The weather was supposed to be awful today (and it's not!!)  and I ran out of time yesterday so slapped the old pump in one again with it's leak. I guess I'll pull it again to do the top cover seal, the upshot is I am getting to be a pro at R/R and static timing  .

I guess I could be pissed at wasting the money on a junk pump but, I needed a core IP for a TD anyway, plus I got the correct hard lines and 4 rebuilt injectors, while not a total score at this point still a good deal.

Thank You everyone for your help.

Good job finding the leak! In finding leaks, when soap and water is not practical, shaving cream works well.

Andrew,
Possibly, at this point that may happen, maybe I'll attempt a total rebuild.

I just want to get the leak fixed on the car for now and then possibly rebuild the TD pump as a winter project. I need to pickup a set of calipers so I can measure the shaft and busing.

I was thinking yesterday I wonder what using the Eco plunger and head would be like in the TD pump?  More HP with higher MPG?, Less HP?? or no difference especially with the new injectors. I can get a used Rabbit NA pump that "shouldn't" leak fairly cheap. Maybe put that in for the winter and make an Eco/TD Franken Pump. It would be the total opposite of what most build.

That Idea totally pointless?

Kind of pointless then.
