I've never taken the fuel rails off a series II before, I've always just put them over the windshield. But I need to remove the fuel rail from my car

I'm guessing there is a specialty tool but the guys at schucks (only store open on a sunday evening) knew anything about it.

So what size/kind of tool do I need?

Isn't it the same as the quick clips on a fuel filter? Just pinch the tabs and pull?

I know I've done this before, with no special tools, but I can't remember the exact method.

On the series one motors they use quick disconnects, identical to the fuel filter location. On the series 2 it is much different.

you need one of these

go down to your local auto parts store, they sell little plastic ones in a set (covers most fuel rails). cheap

You either take the tool Haro posted or the plastic tools Sonoma mentions and side them in to the line while pushing the line further onto the rail..then wiggle the lines gently off. There are tabs inside the edge of the lines that hold the line on the rail. The tools push then up gently and don't damage them.

The car I'd taken them off from was a Series II. Still pretty sure it was done without specialty tools, too. Probably easier with the right tool though.

Every S2 SC that I've done has the type that need a tool. Your point is valid in that I believe all the NA motors, at least to a certain year have the squeeze type.

Oops, my bad. I knew in the back of my mind that his was boosted, but I failed to take that into account that the fuel fittings could be different.

JMFC.. I think you did a great job of answering the titled question. And you also reminded us that certain things are different between the different motors.
