Factory fuel line T block thread size question...
On my 98 T/A I have the returnless style fuel system. The main supply line goes into the fuel filter, out of the filter, and into an aluminum T block thingy. On one side of the T block the line comes out and goes up to the fuel rails. The other line goes back to the tank, and to the regulator. I am converting my fuel rails to a return style rail from a 97-98 corvette with the regulator in the rail so I don't need the return line that comes from the T block. Does anyone know what size/threads are of the line that threads into it for the return? I just want to get some sort of pipe plug to block it off and use the T block as a pass through. Thanks for any info, Paul M

BUMP!
Going to be doing this rail conversion this weekend and would still like to know if anyone out there knows the size of the threads. I figured maybe I am not describing it properly so here is the best picture that I can find. I know that the 2 spupply lines are 3/8 steel and the return line is 5/16 steel. Maybe the fitting is some sort of 5/16 inverted flare?

MeentSS02 thank you so much for that post. That is exactly what I have been looking for. I was hoping that I could just find a pipe plug to use, but the combination that you gave should be more than adequate for what I need. Thanks again!

is it really that big? i got mine in today and it looks just like a 6an threading? I got this:-6 AN Male To 14mm x 1.5 O-Ring Fuel, that is right, right? I got the cap too.

Sorry to revive this old thread. I just didn't want to make a new one. Plus anyone searching this will lead them to this thread so they can have the most information.
Please help!
So i have these two lines. I know one line is for the feed but what is the other hose for?
i know the fuel filter plugs in here and one of the plastic hoses from above attaches and goes to the fuel pump assembly. The other port in the tee is for the return and others ive seen a metal line comes out of here. Am i missing a metal line or fitting for the plastic hose?
The vapor and brake hoses running up.
what is suppose to bolt here?
