TBI fuel line fittings

I'm new here so sorry if this question sounds dumb. I'm about to run a new fuel line on my 92 305 TBI. I'm wanting to do all braided Line but I'm not sure how to link the line to the TBI. Anyone know what size and thread I would need for the fitting to thread in like the original line did?

This is a very bad idea.

Never use more hose than actually needed. The remainder should be metal- or hard plastic tubing. Essentially the same stuff that the actual vehicle engineers use.

Either one--suitable metal or suitable plastic tubing will be cheaper, lighter, more durable, less porous, and have a longer service life than rubber-based "braided hose". PTFE (Teflon) liner hose isn't porous, but it's even more expensive.

Re: TBI fuel line fittings

its a temporary setup. I'm ultimatly pulling the gas thank to clean it then putting in new pump, sending unit, and lines. I simply don't have the time or money to do that all right now so I'm throwing a braided line on to replace a bent feed line.
