I would not try to force it into place. They are designed to fall into place and if they are off slightly under pressure it can make a huge leak. Last year I redid my fuel lines with an lines and to keep them short they were nearly straight lines from my fender to the rail which seemed like the right thing to do. I turned the key on to pressurize it all and there were no leaks. Shortly after starting the car as I was walking around the front I saw a fuel start to spray from the back of the rails onto the firewall so I jumped through the window to shut it down. I was not sure what happened as there were no leaks when I would pressurize the system with the engine off and after removing/inspecting and then putting them back on it did nearly the same thing. After some thought I realized that the straight lines didn't allow for any give when the motor was running/vibrating and it only took the right vibration to knock it out of alignment and not seal. I fixed it by making new lines that were only 4" longer, but make a bend that would make the vibrations not be transferred straight into that 90 degree fitting. It was just a case of too much cool shtuff getting in the way of each other. If the 90 degree fitting isn't fitting see what fitting will fit and get it. This is one of the JOYS of AN fittings is that if you do NOT get one fitting that is off by a few degrees and will not fit your f'n lucky.... I have more then a few extras as does almost anyone that decides they like AN fittings let us know what you need and we might have one to help.
