You need to attach a gauge before the fuel pressure regulator, ie at the end of the fuel rail.

Im not sure if it should be same as a cosworth but cosworth fuel pressure should be 3.5 Bar

It should flow from the pump into the fuel rail then into the fuel pressure reg then back to the tank.

cheers mate good info, but where do you fit the gauge, do you need to cut the fuel pipe to fit it.

Is it aeroquip or is it just rubber fuel hose? If its aeroquip you can get a t piece that screws into the -6 fittings and then attach the gauge here.

If it is rubber, take the hose off the end of the fuel rail and get a t piece and join it in with another peice of rubber hose.

Or if you can with your pressure regulator depending on which type you have you can attach the gauge directly into a blanking plug on the regulator itself if it is easy to get too and see.

You only need to remove the blank on the top of you need to adjust the pressure. You remove the blank and there is a screw under there than you can adjust.

Check the pressure first tho as it may be ok.
