That is indeed the timing adapter, but not for a luminosity probe(hence the word PROBE), it's for a pulse adapter.
Line length is irrelevant to proper operation. The lines are NOT all the same length(anyone who's ever taken them all off knows that), and in a hydraulic system that is properly sealed, that line could be 10 feet long and it will still pop-off the injector with the correct timing as long as there is no expansion of the line or couplings. (which there won't be on the steel lines).
Since the vans are timed on a different cylinder, the PO must have switched it over to #4(?) just for ease of access. Try to get at the #1 injector for anything, it's a pain in the butt.
OR he didn't know what he was doing, and didn't use it for timing at all.
Either way the extra length doesn't matter and if it's not leaking I'd be happy. Having more lines IS a good idea however. I just had one crack on me the other day and had to drive home on 7 cylinders with the busted line pouring into a coke bottle, lol. Worked great. Crappy thing is that the only extra line I had wasn't bent right for that cyl so I had to bend it around to fit.
Runs perfect now, though, exactly like it did before.

Yes the line length matters.
And if you take that line off with the adapter and match it with the same line number for an engine without the adapter you will see they are different lengths, and I know this for a fact, you can't just take the adapter off and force the line to fit, it won't work that way.
The best thing to do is just leave the adapter alone, or replace it will a new line of the proper length.

Here's all the numbers you will need. No 1 line for the van doesnt have the pulse adaptor the f-series does. You would want the number 4 line for the f-series if you really want to replace it. Its really just fine where it is.
