Default Help with EFI conversion

How have you guys sorted your induction system as I noticed the K&N cone off my metering unit does not fit?

Now that the metering unit has been removed how is the fuel return plumbed in?

Also what to do with the vacuum hose to the brake servo? Do I need an FRST one?

Hello mate,

Induction wise, I've gone for a Cosworth Group A cone filter and trumpet to fit a T3 turbo and fitted it on to the hose that went from the Turbo to the metering unit.

Fuel system goes:

Fuel filter > fuel rail > fuel pressure regulator > fuel return pipe

Brake servo pipe I've used an XR3i EFi pipe. But you can use any silicone hose suitable to draw a vacuum and use the original fittings and fire trap.

As above matey, I used a fiesta rst vac pipe though. A cosworth cone filter will fit. Just remember the fuel return goes on the regulator not the end of the fuel rail.

Well I picked this from Matt Lewis and I can't get it to fit;

http://www.mattlewismotorsportonline...?productid=338

cannot get a decent grip of the trumpet when fitted in the hose it just keeps popping off. Have tried three different clamps now of varying width and still no joy.

Tried cutting my boost hose to make it fit but the filter is so dam big!

What hose does everyone use cos I probably just cut up a perfectly good hose.
