Fuel Pressure Question
How much fuel pressure should I have on my '94 351. At idle, I have about 32-34 PSI and when I rev it up a little bit, it drops to around 30 PSI. Is this normal? I could not find the specs on my fuel pressure. Any help would be great.

Thanks, it jumped up to about 40 PSI with the vacuum line unplugged. It still drops about 4 or 5 PSI when I throttle it up a little bit and hold it. Is this a sign of my fuel pump dying? The pump in my rear tank is dead, and I would be concerned if the front pump was about to go T.U.. Also, I plan on replacing the pump in the rear tank in the next few weeks, anyone know of a good place to buy one?
