II installed my fass last night and being too late to call anywher I am back at it today. Its all in but I am not getting fuel. If I turn my key it won't prime my system unless I bump the key. Now I have an in tank. pump but didnt put in a draw straw. Is that the reason its not pulling fuel.

 

need the drawstraw...cant pull fuel thru the OEM pump

 

did the same thing as you. i capped off the old pump with epoxy and left it in for fuel gauge and put in a draw straw

 

x3 needs a Draw straw. I got lucky and my truck had the factory pump mounted to the block and didnt need it.
