Dear Half-Mast,
We have several -5 models of
the field deployable environmental
control units (FDECU), NSN
models 2, 3 and 4 are covered
by TM 9-4120-411-14 (1 May
2000) and TM 9-4120-411-
24P (1 Aug 2002). Are there
any TMs that cover the -5?
SSG D.L.G.
Dear Editor,
The 5-KW DED, NSN 2815-01-350-2205, and the 10-KW DED, NSN
2815-01-350-2206, tactical quiet generators need 10 feet of return fuel lines.
According to the 5-KW engine manual, TM 9-2815-252-24P, and the 10-KW
manual, TM 9-2815-253-24P, you make the return fuel lines from bulk stock.
The bulk stock they give you is part number 503-1052. You can find that as Item
3 in Fig 5.
Unfortunately, that part number does not bring an NSN on FED LOG.
Fortunately, we were able to find an NSN that brings the nonmetallic hose by
the foot. It’s NSN 4720-01-483-6467.
I thought you would like to put this in PS.
SFC Wayne Simmons

Editor’s note:
You thought right, Wayne!
Generator mechanics, if you’re doing
maintenance on these engines, check the
return fuel lines. If they need replacing, you
now have an NSN to order more hose.
To get a compressor/reversing valve assembly for the FDECU-5, use NSN 4130-
01-511-7193.
If you have an FDECU-2 or -3 and need to replace the compressor/reversing
valve assembly, you’ll need to order the assembly for the -5. To make it ±
t, you’ll
need to order the parts shown below. Use a DD Form 1348-6, CAGE 1SYQ5 for
part-numbered items.
Dear Sergeant D.L.G.,
The TMs have been updated by industry.
But this upgraded TM, which includes the
FDECU-5, has not been veri±
ed by the
Army. It is a “Commercial Draft”, which
can be obtained by contacting Mr. William
J. Pardy, ECU Branch, CCS Avionics
Directorate, at DSN 992-4256, or by
email:
william.pardy@conus.army.mil
The primary difference between the -4
and the -5 is the compressor/reversing
valve assembly.

The washers and hex nut come
in boxes of 100.
The FDECU-4 and -5 come
complete with the mounting
hardware for the compressor/
reversing valve assembly.
The FDECU is supposed to be
replaced in the future with the
60K IECU.
