Some frames allow you to lift the tank up, I assume yours doesn't allow that?
Could you put a straight extension into the tank outlet then your elbow?

Thanks for replying sorry mines late if i am able to lift tank slight its in frame don't think it would be enough to give clearance i have a valve section straight in tank then Elbow it maybe i have to chisel out a strip of the ply wood base underneath the valve and if necessary grind metal out not what i want to do
