    Manometer Inquiry..327-375 H.P. F.I..

    I have a 1964 327-375HP F.I. roadster and would like to know if I can buy a good used (or new, I suppose) manometer to set the injection up. I had it set up by a retired GM mechanic that had a manometer, but he did not want to sell it.
    This was about 4 years ago, and sooner or later I will probably want to set it up again(the previous mech. has moved and I can not locate him).

    If anyone has some ideas, please advise.

    What pressure measurements do you want to check?

        I think that a manometer checks fuel and vacuum pressure so that you can get a proper balance, but I am not totally sure how it works as it has been some time since I had my engine setup using a manometer. It does connect in-line with one of the injector nozzles and also the vacuum, but not sure of where you pick up the vacuum pressure?

            The correct manometer shows up on eBay from time to time. I have also seen them advertised in the Driveline.

                Larry, If you can "get out of the box" I could propose a method that has 20 times the resolution of the mercury manometer. It is a straight forward method of measuring the fuel pressure and the parts required should cost less that $50. I have used it on more than a dozen units with sucess. talmadge

                        I would like to see a write up on you method also.

                        Thank you,

                            Thanks for all the response. Yes, I am interested in how you measure fuel pressure on the 327-375 F.I. setup.
