Trying to check a part number for vacuum lines 1996 K1500 Suburban F engine

Or are there better different options?

The line going to the turbo is broken.

I have 3 numbers. I do not know that any of them are good 12559401 Looks correct on the picture on amazon but the application guide starts at 1998.

The other 2 numbers, I haven't been able to find a picture for or application info.

I thought I had vacuum lines but I got an email stating my order had been canceled for lack of availability. I ordered ACDelco 12559401 I still wasn't sure that was the correct part number, but it was the closest I could find

Any ideas on vacuum lines?

I know you hate going to town, but the next time you do, you can pick up any vacuum lines by the foot at the part store.

The gasser uses a lot of them for their emission system, they are rubber hoses with varying diameter and can withstand more than the max turbo pressure in this truck.

With the age of this truck, I don't think ACDelco are making those factory vacuum lines anymore. Unfortunately.
There may be left over somewhere collecting dust that nobody even know what to do with it or the purpose.

I'd go with Vac lines by the foot like stated above. It worked for me before deleting vac system. A vendor from the other site sells them for 45 clams, if you want to go that route. I don't think any supporting vendor have them here, but don't want to step on toes.

I do recall that it takes a good parts guy to find them, they aren't listed very well. Its been at least a year since I ordered some for the 99, so it very well could be NLA now.

I am finding more and more that it takes a very good GM dealer parts guy that knows how to look stuff up to help keep these old gals on the road. Mine is great, I make sure and buy some parts to make it worth his while, but I do have him look alot of PNs up and I hit Rockauto and ebay for many of them.

If you have time could you check and see if you can find anymore vacuum lines. For some reason I like to stay OEM on this. For some reason I never wrote down what vehicles I changed vacuum lines on , back when they were easily found

There is a parts list sticky on here with a part number for vac lines 12559401, but a ? mark as whether for S or F engine.
