[AT] fuel problems get expensive - perspectives and reactions

[Grant Brians]

Cecil, I understand what you are going through. The John Deere I just bought
has a similar High-Pressure fuel system and it has multiple sensors to
determine if there is any water there to cause any problem at all. The issue
I see is these modern high pressure systems. Any fuel tank can sweat some
water into the diesel, but I personally think the plastic tanks migh be more
prone to it especially if they have a crack.
     In the case of the John Deere design, I have heard they have far more
problems from false readings on the sensors than actual water in the fuel. I
believe it based on many factors....
     The primary filters on the John Deere I have and also the NH6610S (the
7610 is the predecessor to the TS110 and is just a turbocharged 6610S) are
anything but just a sediment bowl, but both DO have a bowl to drain off
moisture intentionally. The "low" pressure injection systems common in older
diesel engines such as the Detroit in our HD5, the Oliver Diesels, the
Caterpillar Diesels are all not prone to the same level of damage, but DO
have the ability to be destroyed eventually by water in the system. The
electronics are the real bane of all of the new equipment even though they
do give some pretty cool features....

p.s. I was on a business trip this last week in New Mexico and saw some
beautiful country, visited some interesting ag areas and was impressed by
how terribly we control useless ag and wildland destroying development
sprawl all over this country!

I know this is not an antique tractor, but this problem applies to all
diesels.  The late model diesels that are listed as emissioned are the
real problem ones.
My TS110 New Holland that I was so proud of died last Monday morning at
1:00 am while baling.  The fuel tank problem I had had allowed enough
water to get in and overload the fuel filter and ruin the injection
pump.   I have to buy a new pump, my pump is so destroyed.  Pump and
injector tips will be a little over $3000.00
The primary filter on this $60K tractor is a big sediment bowl!!!
I am installing a double filter assembly from a Ford.  My 500 gallon
tank is clear and We keep final filters on all pumps for fuel transfer,
and they are clean.  The tractor tank was the problem.
