Re: Is it necessary to run rubber fuel line from the cab to the frame?
Sure you could. But I would use a short section (6" - 8") of rubber or braided stainless between the steel line and the fuel rail. I would think there needs to be a little something there to take up any twist and vibration, like an OEM setup is.
I don't remember if you are using the stock in-cab tank, and something in the rear. Does the in-cab tank have a threaded fitting on the fuel line into the sending unit?

My pre-filter, pump, and 'vette style filter/regulator is already mounted to the frame, just need to run lines to everything. I was planning on steel all the way from the sending unit to the firewall and running a short piece of braided to the fuel rail. But somewhere along the line, I remember seeing that the stock setup uses a short piece of rubber from the cab floor to the frame rail hard line in the even that the cab twists or moves/whatever...

Now that you mention it, I think I do remember my 68 being that way when I pulled then tank out. Although, it's really not a huge expense for the piece of mind to install a couple AN fittings and a short piece of braided hose there. But I follow your thinking; new mounts, should be little to no twist. But, in the future after you have a few miles on it........

![]() This would kind of defeat the purpose of me trying to not use ANY rubber line (except at the fuel rail...) |
