My frame is about 5 inches thick from the back forward until it starts to bend for the axle. Did your get the steel tank kit or the plastic tank? If you got the steel tank, the fill neck looks like it will unbolt from the tank. You could get one custom bent to clear your frame, I would think, but mine looks like it's in the perfect position. I bought 3/8 steel fuel line that came in a 25' roll so I'll have no splices from tank to pump. Do you have a picture of what's going wrong with your tank? Also, my tank had some "tabs" sticking up through the flange that I ground flush. These holes seemed to be where the bolts for the straps needed to go, don't know why they did it that way. I had to enlarge the holes some to get 3/8 bolt through them.
Good luck and let me know if I can be of any help,
Scott
