On a Tii, Where Does This Hook Go? Below #4 Intake Plenum, Right?

After reinstalling Otto's (the '74tii) head, I'm now buttoning up the intake manifold. In the bag of nuts for the intake manifold was this hook.

 

Am I remembering correctly that it goes on the bottom stud for the intake manifold at #4 cylinder and holds the fuel line as it connects to the plastic line that goes through the firewall? Or does it go on the plenum, not the manifold?

 

I would've sworn that's where it went, but I have two other tiis in my driveway and a spare motor under the porch, and none of them have this hook anywhere I can see.

 

Thanks. I'm 58 and I forget stuff :^)

Think it goes near cylinder #4 for the return line hose

Same on a carb car.  At least mine had it on there from new.

If I might offer a suggestion of a "safety upgrade" ......  

 

That plastic fuel line through the firewall .....  when I had my '74tii in the shop 2 years ago, I had that entire run of 40-yr-old plastic fuel line replaced with steel tubing.

 

Cheers,

I installed a new nylon fuel supply line in my 69. That stuff is thick and tough.

Not a safety upgrade, the plastic tubing collapses when heated, metal won't do that.

Hi 58 year old Rob :) this is 28 year old Raj chiming in...

 

When I saw that pic I thought to myself that I have def seen that clip before. So I went out to my garage where my motor is sitting on a dolly and I found the clip still attached to the engine block. I am pretty sure it is the one you are talking about. Here is a picture of me pointing to it....

 

I cannot see that sort of a clip on my intake at the #4 cylinder. 

 

However mine is a 72tii RHD

Here is another pic showing my starter wire running through that cable holder. (Not very clear due to poor lighting).... However my clip looks like it has 2 bends where as yours has only 1 bend, so I am kinda doubting myself.

adawil,

Yes, Carl, the BMW engineers used the plastic or nylon fuel line because it will collapse and seal if there is extreme heat or fire, so I have been told by Mike Self.

Hmmmm I think that is the one John. Looks like I need to hunt for that clip now.... 

 

Rob on is there any chance you could post some dimensions of that clip when u get a chance? I may need to bend it out of metal.
