Fuel Line question

[34fordy]

When installing a new fuel line, tank to pump, in a 36 pickup, which end is it best to start from, front or rear? Thanx

On my ‘46 Mercury (with the body off), I started from the rear. That was because the kick-up of the frame at the rear is boxed and that seemed to be the logical thing to get the hardest part threaded first. It was not difficult, and I’m sure that having the body off made it vastly easier. Good luck

Since the fuel line needs to be slid into the tank on a 1936 Ford pickup, start at the rear so you can get in fitted correctly.
If you purchased a fuel line from a vendor, there should be enough that when you are at the cowl, you will need to trim some off.

Rear without question.

Reading this thread because I just replaced the line in my '36 pickup. Nels would you explain "the fuel line needs to be slid into the tank"? I also have a new tank and I just cut the line close to the compression nut as usual and it seems fine. Oh by the way after considerable hunting I found cupronickel line not at an auto parts store (nobody had it) but at a hydraulic supply store in case anyone is looking for local stock.

It (the line) only needed to extend into the tank a short bit. You did it just fine

I just assumed that the female fitting at the tank had a tube running down near the bottom of the tank. Am I mistaken?

Ya know, I can't recall the inside of a tank as I haven't cut one open in decades.
What I do recall clearly are all the tanks I'd removed lines from and never was a line protruding more than a 1/2" or so beyond the fitting.

Hmmm... I just put in a Bob Drake tank and since the fuel gauge is not working yet I drove around with a 5 gallon can in the back. I did run out once and it took quite a bit of gas so I think it emptied out pretty good but now I want to run it dry and measure how much it takes to fill it up.

I looked inside a Drake tank for my 36 pickup just now. The angled female orifice attached to the tank has a tube that proceeds down to the bottom of the tank and across to the middle, then lengthwise to approximately the bottom center of the tank. To me this indicates that the fuel line would need to be just 1/4" beyond the ferulle that slides onto the line ahead of the male fitting. But the id of the tube that is inside the tank is larger than the id of the fuel line. I am unsure if this would affect the amount of vacuum required from the pump to suck the fuel to the pump. Possibly this is why someone determined that the 1/4" od of the line should be pushed to the bottom of the tank. I do not believe it was necessary or it would have been in directions at some date in time.
