HELP! Fuel rails 302/351
 

I have a 351 I'm putting in my 93 but I will need to use the 302 fuel rails. How do you get the lines that join them off? What do I replace them with?

You need a special tool. It is very inexpensive and easy to use. I forget what it's called but you can get a set at your local discount or autozone. It looks like a small plastic donut with a slit in it. The slit allows you to slip the proper sized "donut" over your rail. You then simply press the rim of the donut into the corresponding circular slot in the spring loaded fitting. While the spring is depressed, pull the line apart.
