I was wondering where can I find the gaskets for my T3/T4. I need the one that goes to the exhaust manifold, and the other one for the down pipe. Also i need this stuff quick cause im making the manifold right now.
On another note im doing my fuel system, I need to know what size fuel hose do I use. Is it 5/16 or 3/8. Im pretty sure we use 5/16 stock but I dont know if I should up size. Thanx guys

You can get the gaskets from a Ford parts center at a dealership (from an 86-88 T-bird). You should use 3/8" fuel line.
