    Yes! I got the darn fuel leak on the quick fuel connectors ( on top of the supercharger ) so I was wondering what would be the best and correct way to replace them. I have seen the O-ring replacement opting and the change the whole line option, but wanted to know which one is best.

    (Can someone dig up the tutorials please? )

    Also, my trans is not shifting into 2nd. When going into 2nd it just stays in 1st and it revs all the way. It eventually shifts into 2nd after a while. Doesn't happen all the time but seems like it happens more under heavy acceleration.

    Am going to be doing some pretty good work on this car and spending a load of money on it so I want to know how to do things properly before I start to wrench on it. Thanks .

    If you plan on going with fuel rails at some point, I would switch over to SS fuel lines now. I believe there are some writeups in the appropriate section of this forum. Otherwise, parts stores sell a fuel line fix kit with GM quick-fittings.

    As for the trans, first check to make sure you are at the appropriate fluid level. If you have a way to monitor trans temps, I would also check to see what the temp is when it acts up. Lastly, make sure your fluid is clean and not burnt. Might want to do a pan drop after these checks and see how much clutch material is on the magnet. But, these transmissions don't last forever so a rebuild may be in your near future.

    SS line FTW, you can replace the orings but its a real PITA. If you decide to replace the orings, be sure to use viton
