5-KW,10-KW TQGs…
O
perators and unit maintainers, take a look at the main fuel pump, NSN 2910-01-
378-6025, on your 5-KW, NSN 6115-01-274-7387 and NSN 6115-01-274-7391;
and 10-KW, NSN 6115-01-275-5061 and NSN 6115-01-274-7392, tactical quiet
generators.
The main fuel pump will be either a
Purolator, part number (PN) 40193, or a
Carter, PN P61139S.
If it’s a Purolator, you’re in good shape.
If it’s a Carter, make a note of it and mon-
itor its performance. The Carter pump is
having a tough time doing its job when envi-
ronmental conditions are less than perfect.
If you’re already having fuel performance
problems with a generator that has a Carter pump, replace it with a Purolator. NSN
2910-01-378-6025 now only brings a Purolator pump.
One more piece of pump advice: Never use a main fuel pump in place of the
auxiliary fuel pump. You can make it fit, but it will not do the same job and could
cause a dangerous fuel overflow.
For more information on the main pump problem and for instructions on how to
replace a Carter with a Purolator, contact CECOM at DSN 992-4748 or (732) 532-
4748. Or e-mail them at:
donald.youll@mail1.monmouth.army.mail
.
CECOM will also tell you about an Airtex pump that new generator sets will
be using.
