Jan 30, 2018 · An electric fuel pump provides the fuel at a constant fuel pressure. Electronic controls modulate the duty cycle of electronic fuel injection for the throttle position and other factors. While EFI has many more controllable features, at the same time, the cost and understanding of the technology for tuning is much greater. A vehicle derives its energy from a fuel injection system. That is, an injection pump is specially calibrated to pump fuel into an internal combustion engine. This is a high pressure environment, and such systems are designed to work smoothly for minimal loss of energy. PressureGuard routes air from the trailer air supply tank to the tires to maintain pressure at a pre-set level. If a tire’s pressure drops below the pre-set level, compressed air will replace the lost volume and return the tire to proper inflation levels, to reducing wear and improving fuel consumption. the spec for fuel pressure on a tbi is 9-13 psi. you will need an inline pressure checker as there is no port on the line. the exception to this is if the vehicle is a R or V body designation If you know how to use an ohm meter then you could also test the continuity of the whole fuel pump wiring at the relay also.Use a fuel line clamp or other smooth-faced clamp to seal the fuel line where it attaches to the carburetor.
