leaking injector line

[Finnegan1008]

I was working on the truck today and realized I have a single injector line that is wet where it joins the pump. The truck starts perfectly but has a miss when it's idling. I assume these two things may be related.

the rest of the pump is bone dry but there is now a mess in the valley

questions:

If I crack that line open at the injector and see no difference in idle quality is it safe to assume I have found my problem? Is there a better way to diagnose?

Would swapping in a clear return line also be useful? I've heard some say any bubbles and you've got a problem. Would air be telling mmy return lines are leaking?

Since its only leaking at the union should I try to re-torque the line? Or send the pump out for rebuild? New lines? I really don't want to get into this thing twice.

Lastly if I do need a rebuilt pump, who is a reputable source? Again I realllyyyy don't want to do this twice.

Suggest you tighten line first off and see if that resolves all your issues.

This where a set of crow foot wrenches come in handy for the lower lines. (it probably is a lower one )

You must be psychic! Yes it’s the on one the bottom.

I suppose to torque that line the manifold would have to come off? I think I already know the answer but I figured I’d ask before tearing into it

Nope, it can be done with the mani in place. It's not easy , you will need some crows foot wrenches (i don't remember size) and some 3/8 drive extensions a 3/8 drive ratchet and some patience. Remove the air cleaner and using the extensions, go in from the back, you can't get much of a turn at a time and it's awkward as hell and to keep from dropping stuff , tape the extensions together.
I couldn't find the correct size so I took a cheap Harbor Freight one and did some grinding on it to fit, I also ground some on the outside of the jaws to get a little more 'turn'. After all was down I stood there patting myself on the back for a job well done, I realized it would have been so much easier if I had've used 1/4" drive! HF sell a set of socket adapters and one is a 1/4" female to 3/8" male. Hope this helps, please let us know!

If you do remove the manifold to get to it the lines come off in pairs. Do not loosen the support clamps on the lines. If you remove in pairs you will not require any special wrenches.

Question is would it be easier to just remove the intake? My vacuum pump is also seeping oil all over my starter.
