for the T that goes on the back of the block you will need a 3/8 to 1/8npt bushing so you can thread the an adapter into the T.

As for the turbo.....no idea what you have when you say 4an female adapter. The female end would be the braided linethat threads onto the 4an male adapter.

I thought the t25 used a banjo fitting when installed on a stock turbo car.
