V8 over heating

<< < (6/6)

Range Rover Blues:
If I knew of one cheaper, I would have bought it :cry:

As for the vac test, diconnect the pipe to the fuel regulator at the back of the plenum and connect a vac guage to it.  Halfruads used to sell the Gunson's one which is callibrated (honest) with the results you would expect to get in various situations, expect it to read a little lower than callibrated though.

disco-v8:
is that the pipe that goes to the fuel recirculating valve????

or the othere one that goes some where else along the bulk head?????

nigel purnell:
