Thanks for asking your question. I will try and help you out.

To be honest. 35 psi is the correct fuel pressure for a 3408. Actually there is no way of increasing it or turning it up. A higher fuel pressure will not help the engine or give more power. All the fuel pressure has to do is fill the plungers and barrels. 35 psi is plenty of pressure to fill them.

Please reply back if you need more help or have more questions. I am happy to assist.
