Question Fuel Pressure Gauge PSI?

Maybe someone can help me here. When I start up the car I see about 66psi. (Inline and intank pumps) After I drive the car for about 30mins, it will slowly drop to 61psi and hold, but if it is just a short trip, it stays on 66psi. Any ideas?

Thanks

what fuel pump do you have, sounds like your pushing more fuel through the regulator than it can bypass to keep the 58 psi its looking for

if you don't want to live with that problem, your probaly going to want to get a new regulator that will support the fuel needs your pushing.

look for nasty performance posts on here, they seem to be one of the most knowledgeable fuel related vendors.
