I removes the propane system from my 96 f-250 with a 460.
Now I've got a big gap with some missing pieces.
Can someone tell me what I need, I'm a long way from a junk yard.

 

Take pictures of the engine compartment so we know what IS exactly missing

 

I'm limited in my photo ability. All I have are the two tubes with about 8 inches cut out of the middle.
I can attach the tubes with some aluminum tubing, but there is a piece in the middle that a vacuum tube attaches to.

Attached to the throttle body is a piece that has 2 short rubber hoses and a plastic piece that looks like a fuel filter, but has nothing in it,
Part number >PA6=(M+G)40< .This piece attaches to something in the middle of the two tubes.
Can I just plug it off at the throttle body?
