4500 Flatline questions

Can I put an elbow at the "out put" part of the tank and then the male end Quick D that it comes with? I wanna do this so it has a 90 degree bend up towards the valve.
I already have a screw in bottle going into screw in on-off. I wanna be able to take the on-off, off the drop, and slide the dove tail of the Flatline on using the same braided hose to the valve. Get it?
Next question. The drop forward is a Custom Products with a C.P. on-off. Will the dove-tail on the Flatline fit on to the drop forward dove tail? I know it was designed with shocktech in mind?

yes and yes

just make sure to drain the tank first when workin on it and then once done and ya get it filled gas up the gun and spray a little soapy water on the new connections you made.... if there are no bubbles, you are good to go....

pretty much all rails and rail mounts are standred size... i haven't run into any off size ones as of yet

Would teflon tape make sense on those threads

yup it should be fine....

just make sure to keep the tape away from the bottom one or two threads (side gettin screwed in first) to keep any unwanted tape debrie from gettin in the way
