Should the fuel pressure raise on a 99 dodge ram 1500 with 318 engine when you accelarate?
Yes, the fuel pressure should increase slightly when you accelerate in a 1999 Dodge Ram 1500 with a 318 engine. The fuel pressure regulator is designed to maintain a base pressure, but as you demand more fuel for acceleration, the regulator allows a slightly higher pressure to meet the increased flow needs of the engine. The increase isn't dramatic, but a measurable rise is normal.
