There may be some confusion, here.
States don't require catalytic converters; Federal laws do.
(Some states have inspections that check to see if the cats are
physically
present, others don't.)
There are *NO* states that allow you to remove a cat if the vehicle came

equipped with one from the factory, for on-road use.
There are *SOME* states (California comes to mind) that will not allow
the owner to alter the exhaust configuration from the original (as far
as
emissions are concerned), even to make it better (e.g., replacing a
single
cat system to duals).

Subject: RE: 1999 SD HUBS

The Hubs in the 1999 are either traditional manual hubs with "free" and
"lock" positions or if you order the optional electronic shift on the fly
you get the Pulse vacuum hubs like the 1998 Ranger (much better than the old
auto locking hubs). This has the knob on the dash instead of the floor
mounted "help me lever". The hubs have a "auto" setting that will lock and
unlock as you engage and disengage 4x4 and also a "lock" setting that
overrides the hubs and leaves the front end locked in.

As for trailer wiring 4 pin wiring is standard on all Super Duty's. If
you order trailer towing you get the seven wires but there is no plug
attached this year (4 out of 5 we sold previously had to cut this plug off
because they had different ones on their trailers) The wires are taped to
the loom off that 4 pin harness just behind the bumper.


Hope this helps

Please don't do this: the fuel pump depends on fuel passing through it to cool
itself. If you "suck air" with it, you'll be getting a new one soon.

Sorry, but I don't know why it's continuing to pump. Someone else might know.
Just make sure that you don't let your tanks run dry.

I had this happen to me with my '88 F-150 302. The problem turned out to be
the fuel pump relay. I was able to isolate the problem to the relay by
tapping the relay housing when the pump didn't turn off. I believe there is
a Ford TSB on this problem.

There are two relays right next to eachother just behind the air cleaner.
One is for the computer, the other is for the fuel pump. Sorry, but I don't
remember which is which.

and E4OD gets 15-17. Did someone say he gets 15 with a 460?! I want an
overdrive to help highway RPMs, and so I can lower my rear end ratio for
better acceleration :-) What OD will fit the 351M/400/429/460 pattern? And

I also have been disappointed with the mileage; I run mid-grade fuel,

I'll admit that I could go a little easier on the gas pedal. I don't

David....

I own a '94 with the 4.9L six and 83k. I have seen average 18 town, 22
highway. Just recently it dropped by a couple of gallons to about
15/18, but I am expecting that once I run some Fuel Injector cleaner
through it and do plugs, cap and rotor, air filter, et... it will clear
back up. I have almost the same truck you do and when my fuel
consumption has gone up in the past, once I do a good thorough tune-up,
the MPG corrects itself.

An interesting side note: Here in the Chicagoland area, the 4.9 six is
like gold. I am looking for an Explorer for my wife, and every time I
stop at a dealer, they always inquire how I like my truck. Once I tell
them I have that engine in the truck, they slobber all over themselves
trying to get me to trade that in instead of our '89 Probe. When the
4.9 is running in top condition, it's my experience that it's a horse.

Jimbo....

If I am correct, OD lowers the Rpm's when out cruising at higher
speeds... I would think this would definitely gain you some extra fuel.
Mine is the F150 with the "push-button" OD on the E40D, and there is a
distinct fuel economy difference when it is on.

It sounds to me like the fuel pump relay. I am surprised that it hasn't
drained your battery yet. The relay is located aft of the air cleaner. It
is a standard SPST relay, w/ 4 connections ground, switch, 12V IN, and 12V
OUT. I had a problem with water getting into my relay (89 F-250) and
shorting it out, this may be your problem. Since the FORD relay cost $25 +
I installed a $5.00 radio shack relay, which is sealed much better and is
cheaper. Contact me off the list if you want the part #'s of both relays.

Good Luck,

I have a friend that had a F350 with a 460 and a 5 speed. He got 14MPG with the
stock tires. Although his mileage did go down to 5 with 38 inch tires 14 seems
pretty good seeing as though I get only 11 with my 351w.

Subject: Cat Converters

I must comment on your willingness to put a pipe through your Catalytic
converter for the performance gain. Remember this list service covers
the entire USA and many areas do emissions testing, and that could cause
it to fail. A replacement Catalytic costs about $500, so think carefully
before you do any damage to it. Pay attention to what changes are coming
up in your local vehicle laws. The Catalytic Converter doesn't cause a
lot of resistance, but some. I would bet that a quality set of headers
could do more for the system than ramming a pipe through it. Also check
on a performance Cat. My 351 Y'ed into one pipe then into the Catalytic
Converter, then exited it into dual exhausts. If your engine is running
clean and the Oxygen sensor is operating properly (no check engine
light) than the chances of the cat being plugged is minimum. The exhaust
shop will drill a small hole before and after the catalytic converter
and do a pressure differential check to see if it is clogged. If I had
to do it over again, I would leave the Catalytic converter in place and
not mess with it at all.

I get 20 mpg with my 87 Ranger 2.9 5spd od and you want 20 with a 4.9
fullsize? There has to be a trade off somewhere. I would prefer the fullsize
and bigger engine but opted for better milage and live with the smaller truck.

Subject: EEC tests

I wrote to you guys about testing my EEC III ignition system, and somebody
replied with a page for me to check out, but it was for the EEC IV. Are the
two systems very similar? Or is their a page for the EEC III that anyone
knows about? I am having problems with my choke. When I first start up the
truck, it seems to race, so I kick it down, and then the choke opens right
back up (or is it closes?) to make the engine race again. The only way to
keep it from racing is two drive it are keep slapping the pedal, which
probably isn't the best thing to do... Is the choke computer controlled, or
could it just be "sticking"? Again it is an 83 351 W with the 2 barrel VV
carb and EEC III.

Thanks
Casey

Not realy shure could find out in a few weeks whwn he gets back from
School. Not shure if it was stock or not. Try to find out for you.

Subject: gears Vs horsepower

I am thinking about lifting my F250HD and puting 36-38in tires on it.
What would be a better option to keep it from bogging down. Swiching in
4.10 gears or trying to get more horsepower and torque out of my
351wHO. It is putting out about 250hp and ? torque. Which of these two
options would get my tires turning better?
Thanks in advance.

Jake

HEY!! I want free cake tooo!!!
Can I get 25 mpg in my 6X6 Duece and a half with the 460 when I am
finished doing it?
Just joking, my 77 f-150 with the 351M mated to the 4speed gets about
twelve towing a load and about 14 regular.
My 89 F-350 twin cab with the 7.3 normally asspirated Diesel engine gets
17 sometimes at 55mph but when I go to 65, it drops drastically to about
14 But I can load it to the hilt and pull 15K lbs and it will get
about 12mpg. I know this is about gas engines but wanted to get my two
cents in!!!

Jake,
Both options would be great if you can afford it, but if you have to
choose, then don't mess around w/the engine...yet, swap out your
gears. A simple formula for calculating what the new gear ratio
should be is: New tire size/Stock tire size (not necessarily the
current)=% of change. Multiply that times the original gear ratio =
new gear ratio. I would imagine you have metric size tires so you'll
have to convert them to SAE. Let's say you have (since I don't know)
265/75/R16's on now. 265/25.4 (conversion) = 10.4" of section width.
Multiply that times the second number (percentage of width in
sidewall) = 7.82", the height of the tire sidewall from rim to tread.
You double that for the diameter and add the wheel diameter so: 7.82 +
7.82 + 16" = 31.6 for your overall tire diameter. Now we have a
starting point for the first formula. Keep in mind if you want to be
more accurate you should physically measure the tires on the rims
since rim width and mfg. rounding off can make a difference, but this
usually isn't necessary.

38" / 31.6" = 1.202%
New / Old = difference

1.202 * 3.73 = 4.48 (I used 3.73 as example here)
% of difference * current = new gear
ratio ratio

If you have the Dana 60 or the Ford 10.25" axle, I think that 4.56's
would better suit your needs rather than 4:10's, unless you frequent
the highway with your truck. There are other ways to calculate this
too, including checking RPM's at highway speed and using tire size
among others, but this is one of the simplest. Basically it should
keep the truck performing in the same power band you have now, so if
you're happy w/that, that's the way to go. I know there's alot of
info here, so sorry to those not interested, but hope I could help you
out Jake. Btw, a friend has a set of Gumbo Mudders for sale 38.5 x
15.5 x 16.5" so e-mail me off-list if interested.
Take care,
Randy

You should be able to find that on the emissions tag under the hood.
Usually near the engine displacement. You can't just clamp on the gun
and shoot though, when ADJUSTING depending on your ignition system.
If you have an EEC system (TFI-IV or Duraspark III) you have to follow
a procedure in order to be sure of accurate timing adjustment. The
proc. bypasses a module so you can adjust it. I have a manual that
will have the procedure. If you don't have a manual or won't be
getting one anytime soon (Haynes in this case) then e-mail me off-list....
