Well of course you wouldn't need any of Ford's emissions workarounds.

Scott knows exactly what he's doing and has the machine to tune them.

I got to say that steering box is heavy!
Even heavier doing it on your back, using 1 hand to hold it in place and the other to get bolts started.
I went with the Blue Top box if anyone wants to know.

Pulled the box, flushed the pump, install box and bleed the air out of the system.
Just bleeding the system the box felt tighter.

The road test went great, cant believe how much a box could change how something steers.
There is still a hint of darting but I can live with it as it is no where near what it was and could go away once the kingpins loosen up some.

Now to run the rear tank dry so I can see what is up with the new sender reading empty!

Yes, the box is HEAVY! And when you have a nicely painted frame and box and are not wanting to bang one into the other it makes it even harder to get in place.

But glad you got it in, and certainly glad it made a huge difference. I do hope things loosen up a bit with driving.

I am trying to get it to loosen up took it to work today even calling for showers.
The intermittent wipers worked great.
I am looking out for a ZF5 for the truck. A rebuild kit is $130 for the T18 and still no overdrive so thinking putting that money to the ZF5 is the way to go.

This post was updated on .

I have driven the truck to work all week, mileage said 125 but think that may be low?
Truck has run great, steering is getting better, darting left & right, but I could also be getting use to it.

Some mornings we had misting and the intermittent wipers worked great.
Friday coming home and Saturday going back in to work it was raining pretty good.
I am happy I have not installed a rug yet. The windshield is still leaking even after I added more sealer so need to look deeper into that.
But when I got in Saturday morning I saw other areas that were wet. Don't know if the firewall seams did not get sealed, did not leak when I washed the truck 2 weeks ago?
1 was behind the drivers kick panel so the "duck bill" may not be letting water out? And yes both sides are clean as that was done when I first started the rebuild.

I also need to replace the HVAC vacuum check valve because when you pull away from a light you can hear the doors moving.

The only other thing is after driving for a bit when you come to a light and stop you can feel the brakes stay locked.
I think it may be the front but not sure as it does not do if when the truck is cold and if it rolls back just a little or the pedal up a short time it is ok.
I am going to try and shorten the rod between booster & master to see if that does anything.
And for the ones thinking it could be a rubber hose all 3 have been replaced, new booster & master also but I did play with that rod at some point.

So in the 125 miles I am getting 12.49 MPG, first fill up when taking mileage.
That is 65-75 on the high way going to work (4 miles going to/from high way) and the home trip on back roads with stop lights at 45 mph.
I was hoping for better but the truck just got on the road so guess not bad for a start?
Oh got my first thumbs up yesterday at a light

I agree the rod is probably too long. As the brakes warm up they expand and drag, getting warmer and larger.

On the mileage, maybe the choke isn’t coming off quickly enough? That will kill mileage on short trips.

As for the duck bill, I wouldn’t think water would come in there. But maybe?

You've got a lot of 👍 right here. 😉

Gary, I don't have any duck bills in my truck and it seems ok.
If the windshield is still leaking it can go right across the 'shelf' and end up in the corners.

As for the mileage, you really have to consider how much energy is being turned into heat by the brakes dragging.

Another big advantage of electric, is most stopping is recoverd, back to the battery instead of being lost as heat to the friction pads.

Re: 81 F100 flare side custom with 300 six & T18

Yea I have to make the rod a little shorter to see if that will fix the sticking.

They don't seam to be dragging as I don't feel, see smoke or smell them when moving.
It is the last 3 or 4 feet to the stop and you let off the pedal and the front just dips a little but as soon as the truck might roll backwards they release.
I also cant get them to do it if I just move it a few feet and try again, it is strange?

On the choke I will have to check but I know once the motor is running I can drive it with no problem with an OAT of 34*f to 40*f.
It also is not short drives, 30 to 35 miles each way to work a good 30 min drive on the high way at 1am.

I do have more tuning to do as all I have done so far is gas and go LOL
Will see if I can check it over the holidays.

We didn’t feel the brakes on WelderScott’s truck dragging initially, but they apparently were as they eventually locked up.

However, it might have been the rears, which self-energize. So if they drag any they’ll heat up, expand, drag more, and finally lock up. But rolling back would tend to unlock them

Not if you have a 460 and a heavy foot!

My driving to work with the parking brake on (and subsequent need to adjust) attests to that.
And I have the big 12x3 1/2 shoes.

Thanks guys I am on stand by for work, read no work unless they call me, so I will get out and adjust the rod before I do some running around for the honey do list before family shows up Thursday.

Yesterday I used the truck for what I got it for .......... trash run.
Loaded the trash in the bed and my brother & son in the cab and off we went.
They were busy so did not get a picture so I guess it did not happen right LOL

Marry X-Mass everyone :-partybud

My family was here earlier in the week so today was just the wife and I so spent an hour or 2 in the garage.
The rear tank sender stopped working shortly after I get it on the road so I worked on that toady.

Know what it's like to drop the rear tank even empty?
I checked to make sure the wiring was good by shorting out the wires so knew it was the new sender.
Once out I knew what it was, the float was full of gas.
I did test the sender and it works great.
Swapped float from the old sender, drop unit back in tank and tank back up in place.
I hope it dose not leak once I have fuel in the tank.

Yes, even an empty tank is a pain to drop. But good job with the float. Does the new/old one have an obvious hole?

Depending on the truck and it's condition, it's sometimes easier to just lift the bed off.

Glad to hear that you're finally getting to drive the old girl Dave!

I'd say a lot of Bullnose Flaresides have been saved from the crusher these past few years.

Yes you can see where it weeps out and before I removed it from the arm I shook it and could hear the gas in it.
Because I had 2 old senders / floats I used 1 of the floats other wise I would have picked up a new one.

I did not want to remove the bed and risk hurting the paint on the bed or cab.
I also don't have a good way to attach straps to lift it. If I was to use the stake pockets it may bend them.
I would have had to undo the fuel fill doors & hoses, again may hurt the paint on them.

The only thing doing it the way I did is if the vent / fill got hurt as I was able to fill the tank at full blast before this and hope I still can.
The only other thing is hope it does not leak or I will have to drop it again

I did my part on saving a flare side even if I did add "my touches".
I am going to try and get the truck out this weekend, I started yard work the other day I have to finish, and et some good pictures and up date the picture for my avatar.

Re: 81 F100 flare side custom with 300 six & T18

I spent a little time with the truck today.
I have had 2 head light relay harness from LMC for years I was going to use on another projects.
My son used 1 on his YJ Jeep till he swapped to HID head lights and did not need the relays.
I have had them out to add to the truck before I got it on the road but never got to it till today.

Went pretty easy as it is mostly plug-n-play.
Because the harness was used I had to clean up the eye lets for a good ground.
The kit also did not come with a fuse so I went thru my electrical bin and found a 20 amp breaker and wired it in.
There is only a 3" 10 ga wire between the battery hot & breaker so no fear of a short on the "hot" wire to the breaker.

I also gave a few turn up on the head lights as they were a little to low for my liking.
I will take the screw driver with me next time I have it out at night to do a better job of aiming them.
I may also take a wrench to see if I can aim the fog / driving lights but have a feeling I may have to get creative as I don't have the adjustment I thought I built into them.

The relays should make a big difference on the amount of light awa peace of mind that the wiring nor switch will burn up. Let us know how much diff you see.

On the fogs, did you go with oversized holes in the brackets? Or what was the plan?
