I was looking around on my '99 454 magnum yesterday for the tap to attach a fuel pressure guage. Not a permanent mount guage, only a hand held guage for a quick check of pressure. I only had a little while to look because winter sucks and it gets dark at 5:00. Anyway, I didn't find it. Anyone know where it is?

Thanks

EFI/MPI or carb ?

I found it today. It was difficult to see because it is buried behind my closed cooling heat exchanger. It is on the fuel rail in front of the #1 injector. Not a good accessible spot at all. I also found a plug in the rail in back of the #8 injector. I will be mounting a small guage to that plug for ease of checking and adjusting pressure.
