You could let the truck sit for a while and the fuel pressure will bleed off or there is a port with a schrader valve in it thats used to check the fuel pressure mounted on the fuel rails. CAREFULLY with a rag wrapped around it push in the pin on the schrader valve the same way you would let air out of a tire. But remember there will be fuel coming out of it under high pressure so I don't recommend it unless you are comfortable doing this. Good Luck.
