Blundering around trying to find out info...could not find any...anyway my book is not worth a darn.


I am in the middle of putting a electric fuel pump on my 84 and this OEM fuel pump as a third line. Yes I know it has the inbound,outbound(engine side) and then the one in question is what my book is calling the vapor return?

So I need to figure out where I need to loop this line in with and in doing this when I need to consider future install of the Webber carb. Could steer me in the right direction?

:beer:
 
it should go to your charcoal or vapor canister under your hood. should not have anything to do with the fuel pump. off your canister you should have a line going to a vacuum port on either your intake or carb.
 
assuming the book is wrong or I am missreading this but they are calling this one port on this fuel pump " vapor return" I cannot use this line if I am going over to electric. My question is what does this line go to? Can I block this off or should I loop it into the fuel system somewhere else? I dont currently have the charcoal system......both of my canisters was shot.

My first thought with this third port was it was part of the fuel return? I have just never seen the fuel return or part of it return to the fuel pump before turning to the tank. After I went and just looked that is exsactly how it looks:rolleyes:
 
ok........Just like I thought it is a return line. A few months ago I had a problem with the gas coming out of the charcoal canister. Turns out my return line/canister and crap was hooked up wrong.:rolleyes:. How you mess that up....is beyond me.
