I think I am on the same page now. I have the lines already and have them bent up so I am okay there I am just trying to get it hooked up to the tank. I now know I need a 90 degree 3/8" and 5/16" IFF to a ?? NPT. The fittings I got (right or wrong) are the 1/4" into the tank they were supposed to be, but are too small. now I just have to figure out what size into the tank (those speedway ones say 1/8 which should still be too small) and double check the ones I previously bought are IFF to NPT and I will be okay. Thank you both very much!
