[Vwdiesel] More Quantum Questions?

That middle banjo is like an overflow purge outlet that is only on the TD pump.  NA pumps are much simpler.  On my 1.6TD pump I have a short piece of injector fuel line that goes to the bottom of the pump body and hangs in mid-air, open.

I guess if some chain of events happens inside the pump it will dump excess fuel out of here but I have never seen or smelled anything coming out of this one.

Get a second Out banjo, because it is to hard to get the larger ard plastic return fuel line that goes back to the fuel tank off, and plug the small port that the injector return line connects to and put your mighty vac on the large port that would have the hard plastic return line on it.

This way you are sure to be pulling fuel into and thru the pump, not from the return line going to the tank.
I have made this mistake a few times.

Mark Shepherd, you may have solved my problem. My question was about the function of the middle banjo above outlet & it was capped so it couldn't breath. I saved the "steel wool fuzz" that I took out of that banjo bolt, will reinstall it, but use the banjo bolt that came with the rebuilt pump instead. In fact the middle banjo bolt that came with my rebuilt IP was not capped but the OEM one on my Quantum was.  Will try what you said tomorrow.
