Working down the list of running changes that took place during 1967 production at San Jose as the title states this thread we're looking at the routing of the fuel line which changed during 67 production. The change meant that various panels, brackets and lines changed to support and make the change possible.
I'm using this first post as an introduction to the subject and reserving it for later findings and conclusions. The following posts are posted to illustrate the differences between the earlier and later versions.
As in the past I invite others to contribute data points for the survey so they can be added to what I've already collected.
Remember San Jose only in this survey. Need a real build date - style of version of fuel line routing. If no real build date then the first 4 digits or all of the sequential VIN so that the data can be charted for survey and change over dating.
Thanks

Way too long of a delay for this - Forgive me. The conversation about the change over date came up the other day and I realized I had never posted my findings. Like some other surveys I am some what surprised as to how well the data collected has helped narrow down these change over dates in this case to in this case to less than a wee in the spread between the last know of the first version and the first know of the second version. In some we have multiple of examples of this same completion date. SO here are my results as of the current date.
As usual did find examples that there were some cars that did not fit the pattern but these were always "orphans" (no other similar cars built near them) and restored cars that may have lost their original routing when the floors and other panels were replaced and the original patterns were forgot or ignored.

- Mustangs/Shelby's completed on March 16, 1967 had the earlier/first routing
- Mustangs/Shelby's completed on March 22, 1967 had the later/second routing
Leaving us with an unknown period of five completion days at San Jose during the 67 production period
This tightens up the dates from earlier by 2-3 weeks
Hope this information helps others

Earlier/First "inside" routing
I1- This picture illustrates a V8 equipped 67 Mustang. In this version the line is a one piece tube from this point (really the short section inside the engine compartment) to the rubber hose that attaches it, at the rear, to the fuel sending unit.
Arrows are placed in the pictures to help others follow the line along its route

I2- Along the drivers side front frame rail
(http://www.concoursmustang.com/forum/gallery/14/6-050620163739.jpeg)
I3- Under the frame rail
(http://www.concoursmustang.com/forum/gallery/14/6-050620163752.jpeg)
I4- Along the inner surface of the drivers side frame rail
(http://www.concoursmustang.com/forum/gallery/14/6-050620165640.jpeg)
I5- Past the transmission mount and aligns itself with the rear brake line and the drive line tunnel.
(http://www.concoursmustang.com/forum/gallery/14/6-050620163821.jpeg)
I6- Travels rearward down the driveline tunnel to just in front of the rearend
(http://www.concoursmustang.com/forum/gallery/14/6-050620163836.jpeg)
I7- Takes a bend out to the rear frame rail on the driver's side.
(http://www.concoursmustang.com/forum/gallery/14/6-050620163851.jpeg)
I8- Line takes a sharp bend where the floor and frail meet
(http://www.concoursmustang.com/forum/gallery/14/6-050620165704.jpeg)
I9- Follows the rear frame rail to the front edge of the trunk or gas tank drop.
(http://www.concoursmustang.com/forum/gallery/14/6-050620163904.jpeg)
I10- Takes a couple of bends to align with the gas tank mounting lip. The arrow shows that on this example the line has slipped out of the last retaining clip just before the sending unit connection.

Later/Second "outside" version.
O1- For consistency I'm using another V8 car for the comparison and to illustrate this section of the route.
(http://www.concoursmustang.com/forum/gallery/14/6-050620172950.jpeg)
O2- Rear wheel well picture
(http://www.concoursmustang.com/forum/gallery/14/6-050620172922.jpeg)
O3- Front fuel line enters and passes through the drivers side torque box
(http://www.concoursmustang.com/forum/gallery/14/6-050620173004.jpeg)
O4- Exits the rear of the torque box and travels down the exterior surface of the front driver's side frame rail.
(http://www.concoursmustang.com/forum/gallery/14/6-050620173016.jpeg)
O5- At the rear end of the frame rail the long rear fuel line takes a jog and aligns itself with the rocker panel pinch weld.
(http://www.concoursmustang.com/forum/gallery/14/6-050620173029.jpeg)
O6- Line travels down the pinch weld towards the rear of the car.
(http://www.concoursmustang.com/forum/gallery/14/6-050620173043.jpeg)
O7- At the rear spring front mounting plate in the unibody the line turns inward and passes under a fuel line guard. Marked by the blue arrow, then takes a turn parallel to the rear frame rail.
(http://www.concoursmustang.com/forum/gallery/14/6-050620173056.jpeg)
(http://www.concoursmustang.com/forum/gallery/14/6-050620173111.jpeg)
O8- To the rear of the emergency brake cable mount the line bends over to the inner frame rail surface and travels rearward to the gas tank drop section of the rear/trunk floor.
(http://www.concoursmustang.com/forum/gallery/14/6-050620173126.jpeg)
O9- Line finally bends towards the center of the car, following the lip of the gas tank floor opening to the sending unit.

This car in the pic has the earlier. So does the Shelby.
-
Mine listed in the subject line has the early inner style.
-
Mine has the early one piece style running in the tunnel.
-
Our 67 SJ GT convertible built 11-04-66 was the early one piece gas line.
-
Thanks got everyone's data entered.
So far I'm focusing in on the 7R188xxx-7R195xxx range. Approx Early March to Mid April period. So cars in that range are important if we have them.

Jeff,
7R03A193368 had the two-piece fuel line.

Thanks Pete. Do you happen to have a real build date for the car?

The VIN date falls in about the 21st (a Tuesday) to the 23rd of March per Vol 2 of the Mustang Production Guide.

Thanks but for a survey/study real build dates are what really helps place a car. Too many examples with small to big differences between scheduled and real ;)
Especially since we have that option given the available records for the 67 + years
-
The time frame I entered puts the VIN date in perspective, so further research may be used.

Jeff,
No, I never got the Marti Report. Although I think Charles did. The warranty plate date was March 21, 1967.

Should I have a one piece early "in the tunnel" style fuel line? SJ Build Date 2/28/67

Guess I need to update this thread and post the results of the survey.
My first suggestion would be for you to check for physical signs of installation but not know how much work you car has had and since we know information about your particular car I'm not going to do that in a public forum. If you want to discuss those we can take this to a PM
From what I've collected it appears that you car was built during a period when the fuel line was routed down the driveline tunnel

Jeff,
I was able go thru some of my pictures and compare them to those you posted.
1. I can clearly see there is no hole on back side of torque box and no holes along frame rail behind torque box.
2. I do see a hole for fastener for fuel line bracket in the floor pan inside of the back end of the drivers frame rail (a few inches in front of the seat access hole).
This seems to be enough evidence that the fuel line ran down the tunnel on #1341, SJ build 2/28/67. None of these areas were replaced as we were fortunate to have very little rust on the bottom side, no floor panels were required.
thanks Jeff your posted pics definately came in handy!

Great your cars clues match what shows in the survey. :)
Your car was built about a month before the change took place

Results of the survey have been posted in the first post in this thread.
