New fuel lines on top of frame?

[jasonv]

So if I am running new hard lines would it be worth running them on top of the frame rails? Stock 302 dual exhaust, heat was never a problem but since the tub is off...

Also I have been reading about right side fuel supply for EFI engines. Someday I hope to put a 5.0L in here but it's not going in now. Would it be over kill to run a right side hard line for future use? Do I need a return or I thought I read that they went return-less in 98?

Thanks,
Jason

Overkill, I ran a supersingle exhaust just so I would have plenty of room on the drivers side. I have a cheap plastic filter, a low pressure pump pumping into a 3/4 gallon surge tank, then another cheap plastic filter, and a high pressure pump pumping out of it to a high pressure filter mounted on the drivers side front fender for easy acess. I just rerouted the fuel lines to the driverside.

The super single on the left and fuel on the right with plenty of room underneath to work on things.

It is very worth putting a hard fuel line on top of the frame. I say this because of something I saw happen one day while out wheeling with a buddy in his Bronco. As you know the stock fuel line runs along the inside of the frame rail. While on a very steep climb, we snapped a u-joint on the rear differential's pinion, at which point the driveshaft whipped around and cut the fuel line in the stock location, causing fuel to start leaking out at a rapid rate, spraying dangerously close to the exhaust pipe. We could have watched his rig burn to the ground that day.

Granted this is one of those "one in a million" type situations, I've seen it happen. I can think of other things happening with the fuel line in the stock location and to me, there's no more protected spot for it than atop the frame rail. Mine's all hard line except for short pieces of rubber connecting the tank and the fuel pump to my hardline.

So far so good.

Just food for thought, I ran mine on the top down the pass side since the mustang efi was on that side. Now I regret it for 2 reasons. Doing a 2 into 1 exhaust with a body lift I want the exit between the body and frame in front of the rear tire on the pass side but that may invite the vapor lock gremlin. 2nd the explorer fuel rail intake is on the rear driver side.

I dont know about fuel lines on top of the frame, but steel or stainless steel fuel lines are a good choice. I n my 67 and 65 Stang, I used ss lines from the tank to the carb. I have used a short piece of rubber from the tank to an electric fuel pump (near the tank) and ss fuel line up the side of the frame to the fuel pressure regulator, then to the car. Steel lines in my opinion area safe bet; however I do not know if on top of the frame is the best option for you. Some pics always help too.

On top of the frame rail is a great idea, especially while the frame is off. However I would caution you to think of the serviceability of that routing. It may or may not be very accessable to repairs depending on how it was done.
I use as much steel brake line as possible to keep maintenance at a minimum, and keep is clean under the body.

It will be all SS hard line up there.
