other Return Fuel Line Help

[gfairchild]

Does anyone know where I can get a new fuel return line for a 73 2002?

Hard line? I would email Blunt first. He'll either have it or know which direction to point you in. Super helpful.

marketted as aluminum fuel tubing...

Depending on your setup the return fuel line may not be needed

You can make one:  get some steel tubing of the desired diameter, then route underneath the car, keeping it tucked up against the frame rails.

     Or lift the carpet and run the tubing through the passenger compartment alongside the original plastic.  I just had this done by a shop in Ontario, CA

I think you are right but it is NLA.

Not the hard line.  I am looking for the somewhat clear plastic line that runs through the passenger side cabin to the engine compartment.

From your reply in post #7, I am thinking that you are looking for fuel supply line Call Steve @ Bluntech

Be sure you use the correct SPECIAL plastic line, which is self-sealing, in case of fire.

VERY Important!!!!

This is something you DO NOT WANT to replace with metal line.

RAS,

 

Please, I would very much like to know why metal line is a poor choice for the fuel return line.  This is all new info to me.

 

My reasoning for metal:  the fuel delivery line from the fuel pump to the KF is metal and rubber.  And that fuel is under high pressure.

 

Why would the return line be different ??  Simply because of the routing through the passenger compartment ??  Or is there something more beyond that ??

 

In terms of safety: if you get a fire under the hood, at some point all that rubber hose is going to melt away and you'll not get any return line flow through the passenger compartment anyway, be it plastic or metal.

 

Cheers,

 

Carl

I'm confused on this one.  There never was a return line routed thru the car by BMW.   The blue plastic line is a vent/vapor line.  The return lines were metal and routed under the car and it IS under some pressure because fluids won't flow unless the inlet pressure is higher than the outlet pressure and the tank is at atmospheric pressure.

 

Edit: I had my colors mixed up.  Clear - fuel, blue - vapor

gfairchild was actually looking for the plastic line that is routed thru the cabin.

" Not the hard line. I am looking for the somewhat clear plastic line that runs through the passenger side cabin to the engine compartment"

Gave him link on my reply (post #9) and later he replied ordering it from Blunt in the following link/topic.

Yeah, that's not the return line...

I'm definitely confused now, and my tii is in the shop so I can't look at it to see what is what.  And I don't have any pictures available to look at.

 

Cheers,
