LQ4 fuel pressure regulator vacuum hose I have an 01 Silverado with an LQ4 and the stock truck intake. I accidentally ripped one of the boots on the small vacuum hose going from the intake to the fuel pressure regulator, and am having trouble finding a GM/AC Delco part number online. Anyone know if off-hand?

Just to update, I did find the part number. It's GM 12578233. However, the price was ridiculous for a little piece of plastic and rubber, so I went and got one from the junyard. Looks like the same year 5.3 and 4.8 have the identical hose as the 6.0, for those of you that might go looking for one.
