I'm in the middle of my resto project ('79 F150 4x4 SWB) and recently ran all new steel fuel line along the frame rail. Will someone post a picture of the fuel line where it emerges from the frame just above the brake proportioning valve and curves over the left engine tower? There is a factory drilled hole in the top of the engine tower. I'm speculating this is where the fuel line was once clipped but I'd love to have some pics of this area for reference. Much appreciated!

 

Here's a pic of the fuel line before it was removed from the frame. You can see that it comes up out of the frame rail and over the top of the left engine tower, but it's not secured by a clip. I have to believe the small hole on top of the tower was once used to secure the steel line with the typical plastic blue clip. Can somebody lift the hood of their 4x4 and confirm this? I'd appreciate it! I lack one final bend in my new line and depending on how it is supposed to be mounted, that will determine the final bend. Anyone that has ever bent their own lines knows what it's like to screw up an entire piece of steel line for making a "bad" bend.

 

Still needing some advice with this please...Here's a couple of pics showing the new line. You can see that I have one more bend to make to send it straight over the engine tower compared to the angle it currently takes. I believe the small hole drilled thru the top of the engine tower is where I should secure the line to. Please confirm this for me. When I removed the original line, it wasn't secured to anything. Thanks to everyone here!

 

I had the same problem with my set from Inline. I never figured it out and wound up putting a custom bend in it and after it ran along the top of the frame I cut that nut off and ran braided to the fuel pump.
