There is no relay logic or computer control involved in switching tanks.
Just standard relays turning off one pump and turning on the other pump.

I am replying to the list on this subject as well as personally to the
originator... I too am expieriencing problems with this seat. I have a 96
F-350, 4x4 and have only 23,000 very gentle miles on it. I mean "gentle" to
the point that I get geers from my buddies at work. I really take care of
this truck. On with the point, I am seeing a severe degradation of the seats
original firmness and seem to be sitting lower in the seat than I was just a
few short monthes ago. Now I only weight about 190 Lbs. and I do hoist myself
in and out of the truck correctly. One other point which I had presented to
the list members and did not receive much response, my truck is equiped with
the 460 and the block was never painted from the factory. Please if anyone
out there has a '96 with a 460 look at it and tell me if they have the same.
I really want to go at Ford about this, but if all are like this... What can
I do? I am a U.S Marine and it was no small thing for me or anybody in my
opinion to purchase an F-350, these two items are really discouraging.

My '94 Splash Ext. Cab (5 spd man. trans.) came with 3.27's with
235/75R15's stock. My first tire upgrade was to 31x10.5's with the stock
gearing; the truck seemed to lose a little gas mileage and performance
(always downshifting on western PA hills).
I just put a 4" lift, 32x11.5's and 4.10 r&p in the truck; IMHO, this
seems to be the perfect combination as far as final gear ratio goes -
better mileage and performance than even the stock combination and still
doesn't rev all that high at hiway cruising speeds (about 2,200 rpm at just
shy of 65 - plenty fast enough when dodging all these crazy deer).

Thanks. I'm gonna find somewhere that performs this method of injector
cleaning this weekend. I'll let y'all know if it clears up the idle.
Figure I'll try the temperature sensor, also.

Subject: 98 3.0
According to Ford's web site, the 3.0L V6 in the 98 Ranger makes 150hp
5000rpm and 185 lb/ft at 3750 rpm. My 94 3.0 makes 140hp 4800 & 160
lb/ft 3000. I read in some magazine's "preview" (don't remember what
magazine, I didn't buy it), that the only change was a new intake
manifold. I haven't found one in a local dealership yet, has anyone seen
one? If so, did you notice whether the throttle body is integral with the
upper manifold section like the old one (same as used on 3.0's in the
Taurus), or is it removable like the 4.0 & 5.0? I wonder what would be
required for a swap, beyond the manifold itself. The extra 24lb/ft would
be nice, although I'm not crazy about the 750 higher rpm. After all, this
is a truck we're talking about here.
Speaking of throttle bodies, I finally got around to measuring mine the
other day, and it is a "huge" (yeah, right) 50mm in diameter. Does anyone
know what the TB on a 4.0 measures? I have these strange thoughts about
putting together my own upper manifold with longer runners.
The MAF sensor measures 64mm on the engine side, and 66 on the air filter
side. I was surprised by this, as I believe that the 4.0 (at least in the
Explorer) has a 60 mm MAF. Does anyone know for certain? Have I used the
wrong technique in measuring the meter? I used inside dividers and set
them on a scale, so I'm confident about the accuracy of my measurements.
One last question: does anyone know what the 3.0 injectors are rated in
lb/hr? Are they the same basic injector as used on other Ford fuel
injected engines (4.0, 5.0, etc)?
Thanks for your help,

Subject: F350 w/ two batteries
I have a friend with an F350/PowerStroke (Deisel) Crew Cab who is
having trouble figuring out how to jump-start another vehicle given the t=
battery setup. (Doesn't seem to be anything in the manual and he's not
heard back from Customer support at his dealership.)
The questions are: Does anyone know the proper hookup for jumping? Wil=
one of those Cigarette-Lighter to C-L hookups work? Any worries on the
current running down the line to the target battery?
Any other info, tips, or caveats would be very helpful.

Has anyone had any experience with the Tornado air management system?
The following article was on the newswire:
SANTA FE SPRINGS, Calif.--(AutomotiveWire)--Oct. 13, 1997--
New Automotive Device Will Improve MPG!
Got a gas-guzzler in the garage?
Check out the TORNADO.
The aftermarket long ago figured out that if they could just make things
more efficient (intake runners, air filters, exhaust systems), there
always be a place to set up shop. One such company that is finding a
niche in the "small-but-significant-performance-gain" arena is TORNADO
According to an article in Four Wheeler Magazine and "ShadeTree
on TNN, "TORNADO is an air channeling tool that creates a swirling
in the air, allowing the air to move faster and more efficiently by
continuously whirling air around corners and bends -- imagine a
mini-tornado on its side moving through the intakes. It causes better
atomization, resulting in an increase of gas mileage anywhere from 7 to
24%. These figures are confirmed by road testing performed at an
lab licensed by the EPA. The product is easy to install -- 2 to 5
usually -- requires no maintenance, is environmentally friendly and is
affordable addition to most cars and light trucks."

i have a 96 ranger 4x4, and i had 31x10.50 goodyear tires mounted on

I am assuming you have the 3.73 gears, which are good for turning them.
You could go up to a 32 but you would need a body or suspension lift if
you didn't want to tear apart your fenders.

Subject: Re: 6.9/7.3 Questions
Good start Allen on the info. Here is some more with a bit more detail.
In general terms, the same Navistar 7.3L Diesel engine was used between
1987~88 to 1995. During the latter part of that time period, there was a
Turbo option. The Power Stroke, introduced in 1995, had a significant
makeover. The most significant change being that a COMPUTER runs the
engine. The older had no electronics running it. The second biggest
change was the switch from one injector pump supplying fuel to the
injectors, in a PRE-combustion chamber; to, a HEUI injection system (a much
better and more efficient system) that injects the fuel directly into the
combustion chambers. A Turbocharger is Stock.
The performance difference between a Power Stroke, and a pre 1995 model is
like night in day.
The 1998 (or 1999 depending on what dealer you talk to) will be
intercooled. Giving even more power, and effiency when you don't have your
foot in it.
My two cents worth.

Subject: Gas mileage...
I'm looking to improve the gas mileage on my F-250 351W. I have a K&N filter
charger on it and I'm looking to add headers at a later time. I was
basically looking at adding a high performance coil and 8.8 Accel plug wires,
but I was told at SuperShops that the engine was designed to burn at 100%
already. Now I know that this couldn't be true, but I am wondering what good
the coil/ignition system would do for my gas mileage. I don't really want to
spend more than about 200 bucks on the coil/ignition system. I know I can....
