I've got a carbed 302 setup with a mechanical fuel pump. I just bought all the an fittings and adapters I need to install an in-line fuel pressure gauge (under the hood). Where is the best place within the fuel line to put the gauge? Does mounting it closer to the carb get a better reading? I have an in-line fuel filter, and I'd like to just put it right after the filter. Or would it be better at the carb inlet? Thanks.
