Hi

Sorry to revive an old thread.

The rubber tube that measures mpg is connected to the back of the speedo but the other end is not connected to anything...im getting a reading of 16mpg randomly but would much prefer to have it all put back together.

Someone posted a picture on this thread of which area the nib should be to plug it back in...anyone able to shed any light? tried yesterday but couldnt find anything obvious. I have an 89 8v digi.


Thanks

Gavin

If you look where the brave servo pipe goes to the inlet it should be there. Might be teed in might go straight on. It all runs on the same vac system so if you run through you vac lines and cant find any leaking or a t piece. Just tee it in

Cheers for that

So so the clear pipes from the inlet needs to go through the bulk head to behind the speedo or should something already be there?

The clear pipe should go through towards the clocks. From memory. I run a 16v but dont use mfa so its all deleted from the car.
Ill pull the old vac lines out and see if the old lines are labelled. It may help

Right. Mine came from the servi pupe to the ecu and is tead into there to go mfa. Dont ask where it goes through to the clocks because i dont remeber. I seem to think if you look in the scuttle maybe under the ecu tray or around that sort of area
