Finished installing the rest of the fuel lines.
I'm pretty happy with how it turned out.
The one line going from the outlet of the lift pump to the filter is a bit short... but I didn't have enough line left to cut another one.
I'm still getting a few bubbles in the return line though... it seemed to get better after the 5 minutes of idling.
I don't see any bubbles in the line up until the injection pump.
I guess next up is see if there's a replacement copper washer available for under the bleed screw as that should be cheap.
I'm pretty confident that the injector shop that did the rebuild did a good job as they've got great reviews and have been in business for over 40 years.
Would something being wrong with the injector pump itself cause air getting in the lines from that point?
