I had this problem when I first put the rails and vortech on a couple years ago and used a 90° pipe fitting but I switched to a bigger return line and I don't wanna use a pipe fitting again. Basically I have the return line coming out the front of the rails and the fitting is hitting the coolant crossover on the passenger side. I have a -8 male union fitting on the rail and a 45° hose end connected to it. The crossover was dented in at the spot when I got it used and it sits right against the crossover now. Anyone else run into this? What fitting did u use that sealed up and cleared the crossover? I had a male to female 90° fitting on the rail but it doesn't have a lip on the side that threads into the rail so it won't seal up. I was thinkinh of just getting the coolant crossover delete from mmr but if I don't have to spend over $200 I won't.
