I am needing the know the inside diameter so I can put a permanent T fitting on it to check the fuel pump pressures.
I am going to cut the fuel line into for this T fitting.

This fuel line is a 5/16 of an inch fuel line. So you need to get a T fitting for 5/16ths line. The diameter will match the inside diameter of the line but if your fuel line is a hard line then you will need to get a rubber line that will go over it.

If you have a soft line that you are trying to put a T fitting on, then I would just get an assortment pack of T fittings for a couple dollars and then you will be able to find the one that works. However, the rubber lines are almost always 5/16 inside diameter.
