ok ive fitted a rs turbo metering unit but it seems to be not giving fuel out the injector pipes the unit recives the fuel but wen i took one of the 4 top pipes out they are dry? and can some one tell me wot the little black boxes are on each side wich plug in wires go to and wot they do cheers

 

i think one is a fuel cut off and the other is something to do with your ignition

 

ok cheers mate solved one bit for me i know the one on the right is the fuel cut off now i just need help on how to and wot i connect it up to along with the other one nli 2 problems left cheers mate

 

is it different to the 3i one then

 

its diffrent to the 3i one has the to extra bits with the wires i wil try give the fuel cut off power it myt not be opening and leting fuel through until i hook it up just want to know if the other unit with 3 wires in the plug is neccecery all the pipes off the 3i one went straight on thow

 

nothing will come out of the injector feeds until the plunger moves, without moving the plunger it should flow to the cold start valve and fuel return

 

Just to update an old thread, the block on the right is fuel pressure adjuster which connects to the fuel ecu along with the other box which is a position sensor. Unlike the XR metering head, the turbo one uses the flap purely for measuring airflow, it isn't directly connected to the fuel flow part of the head. It sends a signal via the box on the left, and the one on the right responds.
