That peaked my interest. The new Cobra does use 39lb returnless. Saw a set of 8 for $200 on Ebay (new) Also saw those "rare"  36lb FMS injectors on e-bay too they were at $85 for 8. (used but looked great) hmmmmmm...  Anyone have a set of 6 injector clips for the return style injectors??? I even have an extra set of returnless for trade maybe.

Yea there on there all day for that price. When you say "clips", you talking about the injector harness connectors. I can't picture what you talking about.

No, but I do have 2 return style clips, and 6 returnless clips! Maybe I could cough up all six and just give them to you when I do.

I already have 12 returnless clips.
6 currently being used even.
It was a tongue in cheek joke since I found 36lb FMS return style injectors.
At $100 that's half the price of the returnless 39's. Neither one I would ever max so...
...hence the comment.

So are there the return and returnless style clips? Those are the difference between the rectangle and oval?

Early 99 Cougars use a return fuel system and the later models use returnless sytems.
The return system sends fuel up to the injectors and any left over is sent back in the return line.
With the returnless system the computer monitors everything and the exact amount of fuel is sent to the injectors without any left over.
Thats how I understand it anyway.

Sort of.
Think of it as a water main down a city block with 6 small taps off of it, in principle really. The water main doesn't recycle the fuel.
The return system was designed to help prevent fuel vaporlock and hard cold starts as was experienced with carburetors and mechanical diaphragm fuel pumps.
The return system constantly cycled fuel under pressure so that air was bled out and vapor lock couldn't form.
With really high fuel pressure vapor lock is pretty much a thing of the past. The returnless sytem does recirculate fuel and get rid of air bubbles down in the pump itself.
