HFCM module detachment?

just took the HFCM fuel module off of the frame rail to swap it out with a new one but could not get the pressure (engine side) supply and return lines to detach from the module, the tank side are simple quick connect, these are different and I assume there is a special tool to get them off, any help? I had to take the whole casing apart under the truck to get it out of there.

im assuming your talking about the metal fittings...

They are something ford has used for years... There is a tool that slides inside of that metal fitting...to push the tabs outward...then the line will pull off of it. You should be able to get a two sided (one is 3/8 the other 5/16) tool at any parts store..

thanks, that helps, I just hope that replacing the HFCM solves my problem! the pump was cycling but it wasn't pushing any fuel and was getting no suction from the tank side. But i'm no mechanic just know how to turn a wrench
