Advice needed re: Zetec fuel injection system

• Page 1 of 1
I wonder if anyone can could give me some more advice? I'm at the stage of plumbing in the fuel system, filters pump etc. How did others do theirs? - do you have any pics you could share. I'm using a mid-mounted tank sitting between chassis uprights.
I'm a bit confused as I have 4 outlets from the tank, I suspect the large bore one on the top left is the fuel return, the large bore at the bottom is for the feed to the first filter - pre pump, I'm adding a second filter after the pump.
I have a small outlet top right, which I suspect is a breather. But also have another one midway up front of tank. Do you think this would be another return from a swirl tank? - if so could I just seal this as tank has swirl chamber built in?
Where do people recommend for fuel unions? - need a couple of M16 x1.5 with 8mm outlet
Thanks for any advice you can give.

Yes you are correct, just blank off this union it will indeed be a return if you are running another swirl pot. For fuel unions and fittings try Think Automotive, they are very helpful.

Hi
I have just put another post out about the fuel tank system. I have fuel injection on my +2 running with the twink engine and it seems to work OK. I used a system from SpyderCars and the diagram they gave me to connect it up is attached. I have a small issue with minor fuel leakage from the filler tank when the tank is full and the car is driven for a few miles fuel seems to leak out and leaves a mark on the rear wing -- any ideas what might cause that would help !
hope this helps
Bob

Hi Folks
Following my first post I have modified my fuel system to include a second breather and the details are in a post I did on this subject and details are attached in a link to that post. It shows what I did to add a second breather and to seal the fuel cap to avoid the leakage. I guess starting from scratch only the new breather would be required and a sealed cap could be used. So far so good on my system !
Hope this helps best of luck
