I wish I had a stock 85 close by I could crawl under...

Hang on.... I know a guy!


@limp - I got some answers for ya....

limp said:

Problem seems to be fuel lines only, From what I can see they need to be routed differently to work,, The loop in the exhaust that goes over the rear axle hits them.....

Viewing from the back of the car (and keeping in mind, at the time, I was only able to see forward of the rearend about a foot or so due to my point of view), the fuel lines run down the passenger side of the driveshaft tunnel, along the edge where the tunnel meets the floorboard (see 1st pic). Once the driveshaft tunnel ends and it transitions into the side-to-side rearend tunnel, the fuel lines continue rearward, hugging the upward curvature of the rearend tunnel, to the peak of that tunnel. At that point they turn 90° towards the passenger side for about 6". They then turn rearward again for less than a foot before they end and the rubber lines begin (see 2nd pic).

Looking more for a pic showing if the 85 fuel line routing goes into the tunnel, like the newer brake lines do, instead of down he frame rail

Yes, the fuel lines run down the driveshaft tunnel, at least under the rear seat area. They do not at any point (that I could see) run down the passenger side frame rail. I actually think coming out of the engine compartment that they run down the driver's side frame rail until somewhere around the middle of the length of the car. At that point they turn 90° inward, going to the driveshaft tunnel, then up and over the driveshaft while hugging the tunnel, to the passenger side floorboard of the tunnel. At that point they turn rearward and progress as detailed in the previous paragraph. Again, the route from the engine compartment to the passenger side of the driveshaft tunnel is just a semi-educated guess.... I haven't actually viewed that part yet.

Classic lines builds a 85 GT only line, but they have not been able to answer my questions
The picture of it they show does not look much different than what mine looks like and the front of the line in the engine compartment looks completely different..

I still think that particular 85-only line is what you need. But I can't say for certain.... just seems like it would be the needed answer.

Fk it... I might just order this on monday.. What the heck, I don't quite have 911 money or 67 Corvette money in this car ( probably close ) but another $100 or so is not going to wipe out the " spending my childrens inheritance fund"
I really want to get this car back on the ground and get it driving.........

Did you order it?

And don't look at it as spending their inheritance.... you're just re-allocating it, from a liquid state to a tangible asset.

Tried to start up my scoot... Crank no Start... spark to plugs, I smell fuel, plugs are dry... And its my favorite thing, fuel injection.... LOL....
Bought it brand new in 06 off the showroom floor and this is the first time the black b!tch has let me down....

Does hognet.com have a Cranks OK, but No Start Checklist?

limp said:

Some pics of my fuel tank.. The flange on the front right side is bent down and is in the way of the exhaust..
Looked at some pics and the fuel tanks I looked at either had a nice rounded seam with NO extra or if it had a flange it was bent up??

Click to expand...

Yea, my flange is definitely bent up.

I think the carbureted ‘85’s got this tank as well and they had dual tail pipes. Would need someone to confirms that though.

Got which tank?

limp said:

I have looked for exhaust and fuel line diagrams for 85's, and cannot find any on line....

Click to expand...

The fuel system exploded view actually shows the same layout for 1983-1986 V-8's (w/o CFI). So I question whether that fuel system diagram is 100% correct. (Note: I have found other errors in this particular exploded view manual before.)

After further research, it looks like the fuel line routing drawing I have may be correct. I came across the same pic in another source. So here's what I found...

"This" tank was the 79-85 carbureted tank that has that flange turned down. From the pictures of your car I am wondering if the '85 was a one year only. The odds of the aftermarket making a part for a one year only Fox is about zero in my experience. From that and what is offered it looks like they no longer make tanks for the 79 - mid '81 cars, lumped all the late 81-85 cars to one tank, and all the 86-93 cars to another tank.

limp said:

I will try hognet to see if I can find a checklist or at least the next direction to go...

Lol.... that site was just something I made up.... a play on StangNet.com and the No Start Checklist here. Careful, it may be a po rn site of fat chicks!

Gotcha. Yea, I think there's a good chance that tank may have been a one year thing. Makes sense when considering the unique combination of parts the '85 consisted of.

And I agree with your thought on the consolidating of replacement parts. I've come across several parts that have the '85 part being lumped into a multi-year listing, when I know for a fact that they were 1985 only.

limp said:

85 stang guy... Thanks so much for the effort you put in doing this....

Click to expand...

You're welcome. Glad to help. Bring on the next challenge (hope I don't regret saying that ).

Brought back a lot of memories, slithering under the car. The last time a floor jack (and myself too) was under that car was in 1999.... 25 frickin' years ago!

limp said:

Your exhaust diagram is not what I expected, Figured a single muffler and the split back to two tailpipes after the muffler,,,, TY for adding that...

Click to expand...

Again, you're welcome.

The exhaust arrangement is why an 86-93 h-pipe, combined with 86-93 headers, is a bolt-on deal on 85's. Waiting in the wings, I've got a set of 86-93 BBK shortys and a barely used 93 h-pipe. Flowmasters have been on it since the mid-80's, and since they were welded in where the stock mufflers were, everything should bolt together, theoretically.... fingers crossed.

limp said:

Hope to pull the fuel tank later today and see if I can bend it....

Click to expand...

I'd definitely give it a try. You said you had a heat gun, right? Those can get pretty damn hot. I'd heat the heck out of that corner, put some vice grips on it and I think it'll give way easily. It is relatively thin metal, so I think you'll be successful. Fingers crossed for ya.

limp said:

Got me on that one... It went nowhere,.....
And remember, Fat chicks need love too.....

Click to expand...

Haha.

And you can cover my slack on your 2nd sentence.

Looks good man!

@limp - I added a comment and the fuel line routing exploded view to my post # 42 above.... just so everything is together there. It doesn't quite match exactly what I observed on my car, but it's pretty close. It appears to show an extra bend before the partial-loop over the rear axle.... dunno.

limp said:

...... The additional diagram looks more like my fuel line rather than yours....
You can see where after it turns back along the tunnel for a bit, it turns 90 degrees to the sub frame, then 90 degrees again towards the back and rides along the sub frame where it dumps into the attached.. .....
I still have hope for the " 85 only" fuel line at Classic will be like yours...

Click to expand...

Yea, I agree. Mine definitely doesn't make that 90° turn to the frame rail.

That fuel line you're getting has gotta be it.... what else could it be?

limp said:

Looking at Late 84-85 fuel senders,,, I bet the clocking is different where the rubber line attaches to it... I would guess they are pointed more towards the center of the car than the 82-84 senders...

Click to expand...

That would make sense.
