fuel line?

[shmed]

ok on the t  we've been messing with someone removed sections of the fuel line an line to the charcoal canister.
i have the line from the filter ran to the fuel rail now I'm trying to run the line from the regulator to tank ,  now the tank is  still installed an just before the motor on the passenger side are 2 lines one is 5/16   an the other is  1/4,  will it matter if i just tie into the 5/16 line?  considering thats what it is coming from the engine?
thanks

You should be fine. The orifice on the solid return line is nowhere near 5/16".

Luckily found this post. As my fuel hose got worn out and leaks, and I have to replace it (the one of those two I've got on the passenger side). I didn't have a chance to measure the right diameter, and looks like now I know what size I need. Will now try to find a brand-new hose online, and finally fix this leak!
