Been thinking more about the fuel supply for the 408 build in my fox capri.. Read thru the past posts and couldn't find the answer..  Right now I have the 5/16 stock line coming out of original tank. I compared prices and types of fuel lines and figured I'd ask the "pro's" before buying anything. I have the Holley electric HP 150 pump 140gph. I'm thinking i'll probably go with the Aeroquip lines considering i've heard lots of good things about Aeroquip. Still kinda undecided though. I'm going to run the line from the tank up the rear frame rail and most likely on the one side of the top of the trans. tunnel. Unless that doesn't seem like the safe spot to put it?? I can't really attach it to the sides of under car for the fact that it's too close to the elements from roads..I was thinking about going with 8AN line but not quite sure yet. Question I have is should I go with stainless braided, solid tube, or the synthetic elastomer runner type line? Again this is gonna be a street performance car with occasional track time and car won't see gravel roads or anything like that. Any help would be greatly appreciated!!!

No, the trans tunnel is NOT a safe place for fuel lines or brake lines. In fact, a sharp tech inspector at the track may just bounce you out if he sees a fuel line run in the trans tunnel. I'd recommend going with larger solid tubing until you get to the engine compartment, then go with SS-braid in the engine bay. Why not trace the same layout location as the stock line you're replacing? Invest in or borrow a tubing bender and with a little patience you can bend the solid tubing to look like it was OEM. Use enough tubing clamps to secure it adequately and use grommets to protect the tubing when you go through any framework. Good Luck!

The weird thing is the stock fuel line runs up around the rearend and up to about the middle of the car in the tunnel. Then it cuts over and goes up the driver side and behind the splash guard on the fender to engine compartment. Guess the engineers weren't too worried about a 4cy 4speed breaking a driveshaft in it!!Does everyone usually run solid tubing for the fuel lines?? Thanks again

CRC,
I don't know if the fuel line routing that you describe is OEM or not, but you're right - it does sound a bit weird to me too. Either way, I wouldn't follow THAT course. I think I'd consider running it down the left (passenger) side of the car, just to the outside of the frame rail, go thru the torque box and into the front wheelwell, up across the top of the wheelwell, then into the engine bay in front of the shock tower. I think most folks run solid tubing because it is much less expensive than SS-braid and their manditory high-dollar fittings (with tubing you can simply use a tube bender to make turns/bends). Secondly, solid tubing is easier to hang/secure & look good. SS-braid takes ALOT of hangers to keep it tucked up and not drooping down...... Just my 2 cents,
Ryan

Whats the best solid tubing? Probably alluminum so it doesn't rust?? I was thinking about goin with that rubber elastomer fuel hose but considering its a street driven car i was kinda deciding against it for the fact that something might puncture it. And yes SS braided is pretty pricey. You can get AN fittings that adapt the solid tubing to AN connections right?? Guessing 3/8 is big enough or should I go bigger?? Don't know if any bigger would flow good pressure with my pump or not?

I used Aluminum 3/8 fuel line. It's very easy to work with. I ran it from the tank tp pump and to the carb. I did use a lot of rubber insulated clamps to keep the line from moving. I ran it on the inside of the frame.------------------

The factory stock fuel line in our fox body stang is run in the same manner as yours. The previous owners ran aluminum line up the driver's side frame rail, just one of the numerous things they did that I dont care for. I ran aluminum line on my granada, but I used -10 AN braided on my 'stang. I got a helluva good deal on it, and I couldn't pass it up.

I ordered some 1/2" od aluminum line from summit yesterday when I ordered all my parts.. Was gonna just use the 3/8 line cuz my bro already had some in our shop but figured the wall thickness kinda reduces the inner diameter so decided to go with the 1/2".
Have no clue what i'm gonna use to adapt to the tubing though.. Prolly just use the adapters and run braided to finish it all up.While i'm thinkin about it.. is there any replacement sending unit/pickup tube I can get for direct replacement for my 5/16 one that's in my tank now??

Nope.
The 68 up Mustang senders were 3/8 but are long discontinued and the re-pops are 5/16.
You can remove your sender and have some new tubing brazed in.------------------
