Isn't there a minimum runway length to have an ILS, like 4000ft?

There might be a minimum but it doesn't appear to be 4000 feet.

Oh! I'm sorry for being incomplete there. I forgot to mention that
I was looking at runways with full ILS or just localizers. The FAA
groups everything under "ILS"
http://aviationtoolbox.org/old/ATA-1...ats/Apt_rf.txt

L AN 0010 00072 I22 INSTRUMENT LANDING SYSTEM (ILS) TYPE
ILS - INSTRUMENT LANDING SYSTEM
MLS - MICROWAVE LANDING SYSTEM
SDF - SIMPLIFIED DIRECTIONAL FACILITY
LOCALIZER - LOCALIZER
LDA - LOCALIZER-TYPE DIRECTIONAL AID
ISMLS - INTERIM STANDARD MICROWAVE
LANDING SYSTEM
ILS/DME - INSTRUMENT LANDING SYSTEM/
DISTANCE MEASURING EQUIPMENT
SDF/DME - SIMPLIFIED DIRECTIONAL FACILITY
DISTANCE MEASURING EQUIPMENT
LOC/DME - LOCALIZER/
DISTANCE MEASURING EQUIPMENT
LOC/GS - LOCALIZER/GLIDE SLOPE
LDA/DME - LOCALIZER-TYPE DIRECTIONAL AID

and I was examining anything with "ILS" or "LOC" in the type. Here's
a better list.
SXL, 04, 3015, 50, ASPH-F, SDF
VVS, 05, 3458, 100, ASPH-F, LOCALIZER
HIE, 10, 3495, 75, ASPH-G, LOCALIZER
PVC, 07, 3500, 100, ASPH-G, ILS/DME
DUT, 12, 3900, 100, ASPH-G, MLS
FCM, 10R, 3909, 75, ASPH-G, ILS
BTP, 08, 3998, 100, ASPH-F, ILS

Hmmm...looks like I should have just gone straight to the ILS file
instead of looking at airport/runway info.
